Abstract The distinction of squid species in the genus Doryteuthis is not easy due to their morphological similarity, lack of conspicuous specific characters, and overlap geographical occurrence. This difficulty has leading to an almost exclusive molecular approach, and a premature neglect of the morpho-anatomy. To emphasize that the squid phenotypic features can be useful to identify, as well as to perform any comparative analyses (such as taxonomy and phylogeny), two close species were selected as outset. Doryteuthis pleii and D. sanpaulensis are common sympatric squids in Brazilian waters, commonly used in fisheries, not so difficult to distinguish by external features of the adult specimens. The samples were analyzed from biometric data to dissections, and the found most expressive characters to distinguish them are the mantle-fin ratio; morphology of the tentacle club, its ratio compared to the mantle length; hectocotylus morphology and nidamental gland morphology.

Abstract With a big territory and variety of biomes, Brazil is one of the most diverse countries in the World, with insects massively contributing to this diversity. Although presenting impressive numbers, many groups are poorly known concerning their diversity and distribution. Also, the knowledge of the species diversity is very heterogeneous when comparing Brazilian states and regions. With a recent review of part of Lawrence Quate’s collection deposited at Natural History Museum of Los Angeles County, more than 70 new geographical records for Psychodidae species were found on the Neotropics, including one genus (Eurygarka) and seven species first recorded to Brazil. The complete known distribution of these species was compiled and is presented along with new records for other 11 countries of the Neotropical region. On the Brazilian territory, most of the new records are for the state of Rondônia, on the northern region, followed by Minas Gerais, on the southeastern region.

Abstract Taxonomic notes are provided in some Acanthoderini genera. Three new species are described: Scythropopsis intricata Santos-Silva, Botero and Wappes from Mexico, Aegomorphus robustus Santos-Silva, Botero and Wappes and Eupromerella boliviana Santos-Silva, Botero and Wappes from Bolivia. The following synonymies are proposed: PsapharochrusThomson, 1864 as synonym of Aegomorphus Haldeman, 1847; Acanthoderes (Psapharochrus) albomaculatus Fuchs, 1963 and Acanthoderes griseomaculataZajciw, 1971 as synonyms of Symperasmus alboniger (Bates, 1861); Pteridotelus contaminatus Thomson, 1865 as synonym of Scythropopsis melanostictica (White, 1855); Psapharochrus jameswappesi Tavakilian, 2018 as synonym of Aegomorphus wappesi (Galileo, Martins & Santos-Silva, 2015); and Psapharochrus histrio Casey, 1913 and Psapharochrus guatemalensis Casey, 1913 as synonyms of Aegomorphus circumflexus (Jacquelin du Val, 1857). Acanthoderus circumflexus Jacquelin DuVal, 1857 is proposed as nomen protectum and Acanthocinus rusticus Klug, 1829 as nomen oblitum. Aegomorphus contaminatus (Thomson, 1965) is revalidated. Scythropopsis Thomson, 1864 and Symperasmus Thomson, 1864 are herein elevated to genus rank. The geographical distribution of ten species is expanded and a key to differentiate Acanthoderes, Aegomorphus, Scythropopsis, and Symperasmus is provided.

Abstract The genus Mytilus comprises a large number of bivalve mollusk species distributed throughout the world and many of these species are considered invasive. In South America, many introductions of species of this genus have already taken place, including reports of hybridization between them. Now, the occurrence of the Mediterranean mussel Mytilus galloprovincialis is reported for the first time from the Brazilian coast. Several specimens of this mytilid were found in a shellfish growing areas in Florianópolis and Palhoça, Santa Catarina State, Brazil. Morphological analysis of the shells and molecular analysis through sequencing of the cytochrome oxidase subunit 1 (COI) confirmed the taxonomic identification. The species is known for its great invasive potential and can become a major environmental problem for seafood business and coastal communities, as it can compete and even hybridize with local species.

Abstract The rio da Dona is an important water body in the Recôncavo Sul basin used as a water supply for the neighboring towns and for agriculture, recreation and subsistence fishing. The knowledge about the ichthyofauna of this river is scarce. In this paper, an inventory of the fish fauna from rio da Dona basin and an identification key for the species recorded are presented. Additionally, taxonomic and conservationist issues are discussed. The specimens were collected in different sites along the upper, middle and lower courses of the rio da Dona. The fishes were anesthetized, fixed in formalin, conserved in ethanol, and identified. In addition to the material collected, specimens previously deposited in the ichthyological collection of the Museu de História Natural da Bahia were also analyzed. Twenty species, distributed into 16 genera, ten families, and four orders were recorded. One of these species, Aspidoras kiriri, is endemic to the rio da Dona. Four species, Cichla pinima, Coptodon rendalli, Poecilia reticulata and Serrasalmus brandtii, have been introduced into the river. Higher richness of native species has been recorded in the upper course of the rio da Dona, while in the middle and lower parts non-native species were also representative. Along the river, a series of anthropic impacts were observed, such as deforestation of native forest including the riparian vegetation, silting and dams, which can probably compromised the resident ichthyofauna.

Abstract This study aimed to verify variations in the form of the sagitta otolith of Menticirrhus americanus as to their ontogeny, sex and stage of such structure. Ontogenetically were found significant differences (p < 0.05) for all shape indices (aspect ratios, shape factor, rectangularity, ellipticity, relative surface of sulcus acusticus) and also in the wavelet of the otolith. The CVA presented a 98.6% correct reclassification of the otolith between interval class. Sexual variations were found in the wavelet and in the relative surface of sulcus acusticus index. Between adult females and young females, differences were not detected in the wavelet and rectangularity, but significant differences were found in all other shape indices. The CVA presented a 79.6% correct reclassification of the otolith of the sexes and stages of life sampled. Young females and adults females showed highest correct percentage of classification. The results of this study demonstrate for the first time the influence of the ontogenetic variation and sexual in the form of the otoliths.

Abstract The Little Chachalaca (Ortalis motmot) is a widely distributed species in the Amazon basin, typically found in riverine habitats. There are two disjunct populations: the northern O. m. motmot and the southern O. m. ruficeps (known as Chestnut-headed Chachalaca). Here we performed a vocal, morphological and plumage comparison between these two taxa. Birds present differences in tail coloration but are otherwise undiagnosable in terms of plumage. Ortalis m. ruficeps is, however, markedly smaller and lighter than O. m. motmot, with no overlap in size or weight. We also found vocal differences between O. m. motmot and O. m. ruficeps, no overlap in geographic distributions and no signs of hybridization across its range. Based on the available data, Ortalis m. ruficeps thus must be considered a valid species, endemic to Brazil.

Abstract Ophryotrocha is the most speciose genus within Dorvilleidae, with species occurring in a great variety of environments around the globe. In Brazil, records of Ophryotrocha are scarce and no specific identification is provided for any of the records. Herein we describe a new species of Dorvilleidae, Ophryotrocha zitae sp. nov. Adult and larval specimens were found in the axis of a fragment of the cold-water coral Lophelia pertusa, sampled off São Paulo’s coast, at a depth of 245 m. Both forms are described and illustrated. This new species resembles O. puerilis, O. adherens and O. eutrophila, but can be distinguished based on differences in its mandible and on chaetae shape and arrangement.

Abstract Piauí, a Brazilian Northeast state, has been considered one of the most important regions for the presence of new taxa in ants globally, especially considering the ecosystems’ diversity formed by the transition of the three biomes in the state, the Cerrado, Caatinga and the Atlantic Forest. Despite the recent increase in studies of ant diversity in the Neotropical region, Piauí still represents a major knowledge gap regarding its ant fauna. Therefore, this study aimed to increase the knowledge about the ant fauna of the state by generating a list of species with data obtained from the literature, online repositories and collection expeditions to the Serra da Capivara and Serra das Confusões National Parks. A total of 152 species in 52 genera and nine subfamilies were registered from 24 localities in Piauí. Fifty-eight out the 152 species recorded represent new records for the state, eight are new records for the Brazilian Northeast Region, and one consists of a new record for the country. Eleven species are here recognized as new for science. Considering the field expeditions carried out here, this work represents the first standardized study for the ant fauna of Piauí. The species list presented considerably exceeds the current number of species registered for the state so far. From the present 48 records, the number of species for Piauí raises to more than 150 with a tendency to increase with the accomplishment of future field endeavors and advances in the study of the local ants.

Abstract The Volta Grande region in the Brazilian state of Minas Gerais is classified as of “High Biological Importance” for the conservation of birds in the state. Despite this, the avifauna of the region has yet to be adequately sampled, as evidenced by the few papers on the region in ornithological literature. The results of an avifaunal inventory conducted between March 2013 and January 2014 in five sites located throughout the region of the Volta Grande Hydroelectric Power Plant in Southeast Brazil are presented. Point-counts, ad libitum observations and mist-nets recorded 224 species for the region, with insectivorous and omnivorous being the predominant feeding habits. Species that are “independent” of forest habitats comprised 52% of the recorded species. Three species are endemics of the Cerrado, 85 are migratory and 33 are under some degree of threat of extinction. These findings demonstrate that the region of the Volta Grande Hydroelectric Power Plant is important for bird conservation. Additional inventories, adequate management plans and public policies aimed the preserving species are needed for more effective conservation of the biodiversity of the studied region.

Abstract In Colombia, the taxonomical understanding of ectoparasites (Diptera: Streblidae and Nycteribiidae) of bats is scarce, despite the high diversity of hosts. This fact reflects the lack of important information on the group and poses the need for studies that expand the knowledge on bat ectoparasites in different regions of the country. The aim of this study was to contribute pioneer knowledge on bat ectoparasitic insects in the department of Caldas, located in the Central Andes Mountain range of Colombia. We assessed 318 bats from four eco parks in the city of Manizales, and collected 234 ectoparasitic insects. We provide the first report of the family Streblidae for Caldas, with seven genera and eight species: Anastrebla caudiferaeWenzel, 1976, Anatrichobius scorzaiWenzel, 1966, Exastinion oculatumWenzel, 1976, Megistopoda proxima (Séguy‚ 1926), Paratrichobius longicrus Ribeiro, 1907, Paraeuctenodes similisWenzel, 1976, Trichobius longipes Rudow, 1871, and Trichobius tiptoniWenzel, 1976. In addition, we report the species Basilia ferrisi Schuurmans Stekhoven, 1931 and Basilia sp. for the family Nycteribiidae.

Abstract Although a recent revision of the genus Glyphidops Enderlein covered most its known, some of the Brazilian forms were not surveyed. Here we take advantage of the excellent morphological work available in the literature and redescribe Glyphidops (Glyphidops) filosus, based on 91 specimens (43 males and 48 females) from the States of Amazonas and Goiás, including Brasília, Brazil. We also provide a study of male genitalia using scanning electron microscopy (SEM) and female genitalia and spermathecae, using light microscopy (LM). We present descriptions of the following structures in male genitalia: epandrium, hypandrium, surstyli, cerci and sections of aedeagus, and in female genitalia: oviscape, bursa copulatrix, ‘S’ bend and spermatheca. An update list of Brazilian species of Glyphidops Enderlein is also presented.

Abstract in English:

Abstract Cascudinhos are a group of small benthic fishes included in the Hypoptopomatinae subfamily, inhabiting small to moderate streams and rivers within the Neotropical region, from Venezuela to Northern Argentina. Until now, Otothyropsis piribebuy originally described from the rio Paraguay basin, in Paraguay, is the only species of the genus not recorded in Brazil. Recent samples in the rio Tererê, rio Paraguay basin, Brazil, revealed a population of Otothyropsis with uncertain taxonomic identity. Therefore, the study aimed to unveil the distribution of Otothyropsis within Brazilian territory. External morphology, osteology, measurements, and counts (plates, teeth, and rays) of these specimens from rio Tererê were compared to data from the original description of O. piribebuy, and also with specimens of O. piribebuy sampled in Paraguayan territory. Observations indicated no differences among the analyzed specimens. Furthermore, a Principal Component Analysis (PCA), carried out using log-transformed measures from Brazilian and Paraguayan specimens, showed no separation of these populations, also indicating that all analyzed specimens pertain to the same species. Based on this, a prediction map of distribution, using Maximum Entropy, was produced. The correct identification of spatial range of occurrence is an essential step to ensure the conservation of species, and the extended distribution of Otothyropsis piribebuy was confirmed, enhancing the list of neotropical fish from Brazil.

Abstract The feeding habits of the cougar have been scarcely studied in Colombia, despite its importance in the ecosystems it inhabits. In this study, we analysed the diet of the cougar using 53 feces samples collected from several sites in the Central Andes of Colombia’s Coffee Growing Region. To identify prey species, we examined and compared bone fragments and hairs found in each sample with descriptions published in relevant literature and with specimens from the Natural History Museum of the Universidad de Caldas, Colombia. We found that rabbits (Sylvilagus sp.) provided half of the relative biomass consumed by the cougar (50%). Other preys identified belong to representatives of medium and large mammals such as marsupials (Didelphis: 10%), sloths (Choloepus: 9%), rodents (Coendou: 10%, Cuniculus: 9%), and deer (Mazama: 9%). Of the preys, Coendou rufescens has not, to our knowledge, been previously included in cougar diet literature. The curve of accumulation of species indicated that the number of samples obtained in this work fully describe the diet of this feline. Neither domestic species were recorded in this work, nor were there any relationships between the dry or rainy seasons and the consumption of prey species. The comparison of the information reported in this study and others carried out in the Andes may indicate the general nature of this feline’s diet and its adaptability to the prey species found in each area, since these vary in each one of them. It is probable that the obtained trophic niche value (0.33) is due to the abundance of rabbits present in the study area. It is also probable that the cougar has not consumed domestic species since, although it is close to cattle ranches, it has enough of wild prey in the area to supply its needs. The results of this study may help to improve our understanding of the feeding habits of this predator and its interaction with other species in this important region of Colombia. This will, in turn, promote major comprehension of the role of cougars in the Colombian Cordilleras and lead actions for their conservation.

Abstract We assessed the current knowledge on non-avian reptile species composition in the state of Rio de Janeiro (RJ), southeastern Brazil. We used published data in indexed journals and verified voucher specimens housed in the herpetological collections of the Museu Nacional (UFRJ), and the Laboratory of Reptiles (ZUFRJ). We also confirmed vouchers from Instituto Vital Brazil (IVB) and from the Museum of Comparative Zoology (MCZ). We compiled a list containing 149 species of reptiles, distributed among Testudines (N = 15), Crocodylia (N = 1) and Squamata (N = 133; six amphisbaenians, 38 lizards and 89 snakes). Our results add 20 species to the previous list known for the state. Four species recorded are endemic to the state of Rio de Janeiro (Anolis neglectus, Glaucomastix littoralis, Leposternon scutigerum, and Liolaemus lutzae). We identified that 21 reptile species recorded in RJ state (nearly 15% of the total) are included in some threat category either in the IUCN, Brazilian (ICMBio) or state lists of endangered species. We also report that seven of the reptiles recorded are non-indigenous to the state: Cnemidophorus aff. lemniscatus (= Cnemidophorus cryptus), Anolis sagrei, Trachemys scripta, Trachemys dorbigni, Hemidactylus mabouia, Crotalus durissus terrificus, and Rhinoclemmys punctularia. The checklist presented here provides a comprehensive database for further research on the herpetofauna of the Brazilian Atlantic Forest.

Abstract The Pampa biogeographic province covers a mere 2% of the Brazilian territory (176,496 km²). However, it stands out as a complex and diverse ecosystem, although its mammal communities are still scarcely understood. Human activities are transforming the territory into a mosaic of agroecosystems, native and exotic forest fragments, and grasslands. Here we conducted the first investigation to determine the richness of small mammal assemblages in the region based on extensive analyses of owl pellets (Tyto furcata). Craniodental remains were studied from samples collected from 12 Semi-deciduous Seasonal Forest sites in the municipality of São Lourenço do Sul, State of Rio Grande do Sul, Southern Brazil. A total of 2,617 individuals belonging to 18 taxa were recorded, including 2 marsupials (Didelphidae; 0.42%), 2 chiropterans (Molossidae, Phyllostomidae; 0.12%), and 14 rodents (Cricetidae, Muridae, Caviidae; 99.46%). The rodent genera Oligoryzomys, Mus, Calomys, and Akodon were the most common taxa. Large samples also included poorly known taxa, such as the cricetids Bibimys, Juliomys (recording here its southernmost occurrence), Lundomys, and Wilfredomys. From a biogeographical point of view, the recorded assemblage embraces a mixture of Platan, Pampean, and Atlantic Forest elements, highlighting the role of the southernmost Brazilian hills as a wedge favoring the penetration of forest micromammals to higher latitudes. Our findings testify to the great diversity of the Pampa, but also point to a growing homogeneity and dominance of rodent species that are widespread in agroecosystems. Rapid inventories based on owl pellets emerge as a suitable, economic, non-invasive tool to document these community changes.

Abstract A new species of moth-fly, Tonnoira igrapiunensis sp. nov. (Psychodidae, Psychodinae), from the Brazilian Atlantic Rain Forest is described. The new species can be distinguished from other species of the genus by its eye bridge separated by 0.5 facet diameter, R5 ending slightly posterior to apex of the wing, gonostyli bifurcated with long arm shorter than length of gonocoxites, aedeagus bipartite and asymmetrical, and two asymmetrical parameres. The gonostylus is similar to that of Tonnoira andradeiSantos, 2014, but in the latter species the aedeagus has only one shaft and not two as in the new species. Tonnoira bifidaBravo & Chagas, 2004, Tonnoira brisolaiiSantos, 2014, and Tonnoira galatiaeSantos, 2014 have their distribution expanded.

Abstract The puffbirds (Bucconidae) are relatively poorly studied birds whose intrafamilial relationships have not yet been explored within a phylogenetic framework in a published study. Here, we performed a parsimony analysis of osteological data obtained following the examination of all the genera and 32 out of the 36 species recognized in Bucconidae currently. The analysis yielded eight equally parsimonious trees (426 minimum steps). Ambiguous relationships were observed only in Notharcus ordii, Malacoptila fusca, and Nonnula rubecula. Notably, Bucco was polyphyletic, leading to the resurrection of Cyphos and Tamatia. In addition, the osteological data provided a well-resolved phylogeny (topological dichotomies) and the support indices indicated that most of the nodes were robust at all hierarchical levels. We thus propose the first revised classification of the Bucconidae.

Abstract The puparium of Dactylodeictes brevifacies was described based on fifty-eight specimens reared in laboratory until the emergence of adults. Larvae were collected under the bark of fallen trees in a Cerrado vegetation, Gallery forest; Palm swamp (Vereda) and open grassland (Campo Limpo) in States of Goiás and Tocantins, Brazil (New Record). The puparium was compared with that of Brachyodina lopesi, the most closely related species with a described puparium. Despite this species clearly shared the larval pachygastrinae features it has a remarkable character not know before for this subfamily: the presence of four pairs of ventral setae (V) in the eighth abdominal segment in ventral view, while in other larvae and puparia of this subfamily, there are five pairs of ventral setae. The adult male and female were described and figured.

Abstract The Andean bear (Tremarctos ornatus) population density and relative abundance within the Chingaza Massif were assessed between September 2015 and May 2016. One hundred seventeen (117) camera traps were installed at 9 grids: 13 cameras per grid, each camera separated 750 m from the other; the sampling effort was 17,057 days-trap. Two thousand seven hundred eighty-four (2,784) native fauna records were obtained, 1,456 corresponding to mammals, 183 records for Andean bear specimens, 158 of them independent bear records (at least one hour between records), and 106 effective-independent bear records (also permitting individual recognition). Fifty-seven (57) Andean bear individuals were identified according to key external morphological features. Sixteen (16) adults were recaptured (12 males and 4 females), with a maximum mean distance of 27.22 km. Bears population density was 2.9 bears per 100 km². Based on this density and the buffer area of the sampling grids, we estimated an overall number of 122 bears in 4,215.15 km². The estimated density is the first for the species in Colombia and the lowest regarding previous reports from other countries. Thus, it is necessary to better understand how integral habitat quality and the anthropic impacts on habitat quality, availability, and connectivity may affect the Andean bear population densities in Colombia, as a useful tool for assessing populations` state and focus future conservation actions.

Abstract Bee populations are declining because of various synergistic threats, and therefore bee survey and monitoring programs are needed. Several techniques have been developed to survey bees, but the most cost-effective and suitable methods to sample bees in several sites at the same time are passive approaches, such as methods involving colored pan traps (also known as Moericke or bowl traps). Several bee surveys using pan traps have been conducted in North America, Europe, and Australia, but only a few such surveys have been done in tropical regions. We used colored pan traps (blue, yellow, and white) to assess the bee community in the Brazilian savanna ecosystem in Rio Preto State Park. Sampling was conducted in October 2013 and March 2014 along permanent trails. We also characterized the local habitat of each trail, and then we compared bee abundance with habitat complexity. In total, 187 individual bees (n = 15 species) were collected, mainly using blue and white traps. Although we were not able to sample most species that were previously recorded in this park, the pan trap method can be used to survey and monitor bee assemblages in combination with another sampling method. Habitat complexity also affected the numbers of bees sampled using the pan traps, and more bees were collected at open sites.

Abstract Several plant-related factors can influence the diversity of gall-inducing species communities. In the present study we performed an inventory of gall-inducing arthropods and we tested if the plant species richness and the abundance of super-host plants (Copaifera oblongifolia) influenced positively in the diversity of gall-inducing arthropod species. The study was realized in an area of Neotropical savanna (cerrado sensu stricto) in the Environmental Protection Area (EPA) of Rio Pandeiros, Minas Gerais, Brazil. Host-plant species and gall-inducing arthropods were sampled in 18 10 × 10 m plots distributed in the vegetation. In total we found 40 arthropod gall morphotypes, distributed on 17 botanical families and 29 plant species. Cecidomyiidae (Diptera) induced the most arthropod galls (85%), and the plant family Fabaceae had the greatest richness of gall morphotypes (16). The plant species Copaifera oblongifolia and Andira humilis (Fabaceae) were the most important host species with five and three morphotypes, respectively. Galling species richness was not affected by none of explanatory variables (plant species richness and abundance of super-host plants). On the other hand, galling species per plant species was negatively affected by plant species richness and positively affected by abundance of super-host plants. This is the first study of arthropod-induced galls conducted in EPA of Rio Pandeiros, Brazil. Our results corroborate previous studies that highlight the importance of super-host plants for galling arthropod diversity on a local scale.

Abstract Several deep-water mollusks collected during the Marion Dufresne MD55 expedition off SE Brazil have been studied in recent papers. The present work focuses on eight species belonging to the cerithioidean families Cerithiidae, Litiopidae, Modulidae and Planaxidae. Three species have their geographic distributions greatly expanded: Bayericerithium bayeri Petuch, 2001 from Pernambuco to Rio Grande do Norte and Ceará states (north) and to Bahia and Espírito Santo states (south), Brazilian coast; Ittibittium oryza (Mörch, 1876), from the Caribbean to the SW Atlantic; and Angiola lineata (Costa, 1778), from Trindade Island, Brazil to the Abrolhos Slope, nearly 870 km westward. Four species reported herein had their bathymetric ranges greatly expanded: Alaba incerta (d’Orbigny, 1841) from 0-40 m to 300 m; B. bayeri from 0-2 m to 120 m (live specimens); Litiopa melanostoma Rang, 1829 from 0-805 m to 1,550 m; Fossarus orbignyi Fischer, 1864 from 0-40 to 830 m (shells only).

Abstract Pisidia longimana (Risso, 1816) and P. bluteli (Risso, 1816), both described from Nice, France, have been considered each other’s synonyms or have been validated depending on successive taxonomic opinions. The validity of both in respect to P. longicornis (Linnaeus, 1767) has also been contradicted a number of times. The current lack of clarity in the use of the names P. longicornis, P. longimana and P. bluteli has resulted in nomenclatural instability, but also in unreliability and miscommunication as regards the available ecological and distributional information. The validity of P. bluteli and P. longimana is revisited herein based on a large number of specimens (241 males, 190 females and 33 juveniles) from many different localities. The latter species is confirmed as a junior synonym of the former, whereas P. bluteli and P. longicornis are herein considered separate species. Diagnostic characters and morphological variations are discussed and illustrated.

Abstract Seven species of the genus Chiromyza Wiedemann are recorded in Brazil: C. brevicornis (Lindner, 1949), C. enderleini (Lindner, 1949), C. leptiformis (Macquart, 1838), C. ochraceaWiedemann, 1820, C. stylicornis (Enderlein, 1921), C. viridisBezzi, 1922 and C. vittataWiedemann, 1820. Herein I describe a new species, Chiromyza raccai sp. nov., based on 88 specimens (41 males, 47 females) from the Atlantic Rain Forest mountains of State of Rio de Janeiro, Brazil, in the city of Miguel Pereira. The new species is distinguished from the related species C. ochracea and C. vittata by the structure of male terminalia. Chiromyza raccai sp. nov. has the distal region of the phallus rounded with two conspicuous apical setae, C. ochracea has the distal surface of the phallus wide and flatness, and C. vittata has the distal surface of the phallus rounded with outer margin rugose.

Abstract The ability of an individual to withstand random perturbations during its development is considered a good indicator of environmental and genetic stress. A common means of assessing developmental stability is through analysis of fluctuating asymmetry (FA) in bilateral traits. Tortoises, with their large, solid plastron, allow for measurement of body geometry. Their bilateral shell scutes are ideal candidates for asymmetries researches. With this issue in mind we assessed, as a preliminary study, levels of plastron scute asymmetry in a sample of 46 red-footed tortoise Chelonoidis carbonaria from Arauca, N Colombia. We found significative fluctuating asymmetry (FA) but no directional asymmetry, the former not increasing with carapace size and thus indicating that tortoise shells do not become increasingly asymmetrical with age, or in other words, signaling that FA is not being influenced by pholidosis (variability of scale cover mosaic according to the development of the scutes). Asymmetry in plastron shape, although not necessarily apparent at first glance, varied, with gender with males exhibiting higher levels of FA than females. Although we can not identify the potential sources of variation responsible for the observed patterns of developmental instability, we consider this detected form of asymmetry due to unfavorable environmental conditions.

Abstract The lack of information on the occurrence of species in a region limits the understanding of the composition and structure of the local community and, consequently, restricts the proposition of effective measures for species conservation. In this study, we researched the reptiles in the Duas Bocas Biological Reserve (DBBR), Espírito Santo, southeastern Brazil. We analyzed the parameters of the local community, such as richness, composition, and abundance of species. We conducted samplings from August 2017 to January 2019, through active search. We performed the samplings in nine standard plots of 250 meters in length. All individuals located in the plots or occasionally on the trails were registered. To evaluate sample effort to characterize the reptile community, we performed an accumulation curve of species, and to update the DBBR reptile list, we used as secondary data specimens deposited in collections and previously published studies. Considering primary and secondary data, we recorded 38 species, one chelonia, 13 lizards, and 24 snakes. Our study showed a richness of 15 additional species to the previous list of reptiles, increasing by about 40% the known richness to the area. We concluded that the DBBR holds a high richness of reptile species, representing 12% of the richness of reptiles of the Atlantic Forest and with a considerable number of endemic species in this biome. This suggests that the DBBR is an important forest fragment constituting a reservoir of the biodiversity of the reptiles of the Atlantic Forest.

Abstract The largest feline in the Americas and the third largest in the world, the jaguar is an apex predator in the food chain and a key species in the ecosystems where it occurs, developing important ecological functions in maintaining ecosystem balance. In Brazil, the Pantanal is considered an important refuge for the species, and protected areas such as the Taiamã Ecological Station (TES) are relevant for conservation of pristine ecosystem where the species persist. Thus, considering that this area is located in one of the regions with the highest concentration of this large cat in the Pantanal, the objective of this study was to evaluate the effectiveness of the protection given by the TES for the jaguar population. The station is a flooded island in the middle of the Paraguay river and surrounded by extensive wetlands. We monitored ten jaguars using GPS collar at the TES and its surroundings. The samples were separated into high-water season (January to June) and low-water season (July to December), and the estimated home ranges were grouped as: 1) residents only and 2) all monitored individuals. The stabilization of the home ranges of eight jaguars, considered residents, was determined through variograms. When all jaguars were analysed together there was 55% overlap between the clustered areas of the two analysed seasons. In the analysis excluding non-resident individuals there was 72% overlap between the clustered areas. The type of land cover inside these areas was very similar between these periods. The range of this protected area is not sufficient to effectively protect these jaguar populations, since the grouped home ranges of the resident animals studied are 3.5(wet)/2.5(dry) times larger than the area of the TES. However, the surroundings of the TES have low human impact and no deforestation and, in this way, the landscape context of the station may have a significant effect on the persistence of a large carnivore like the jaguar. However, it is necessary to create more protected areas in order to prevent possible future environmental changes in the areas surrounding TES.

Abstract Urban areas, as cities, are frequently overlooked as refuges for the native fauna. However, these places may support several species and house relevant biodiversity contributing to important ecosystemic functions. Wasps and bees (Hymenoptera: Apocrita) are important faunistic elements acting as predators/parasitoids and pollinators, respectively. Therefore, they must be surveyed and inventoried for conservation purposes, especially in cities located in the Atlantic Forest domain, a ravaged Brazilian biome. Accordingly, this study presents a species list of trap-nesting bees and wasps that occurs at the Jardim Botânico do Rio de Janeiro. The survey was conducted using the trap-nest method. Three types of trap-nests were offered totalizing 1,038 traps: rubber hose, bamboo cane and plastic straw. The plastic straw traps were the most effective followed by the bamboo cane ones at attracting nesting wasps and bees. Between April/2017 and February/2019, 12 foundress species built nests: Tetrapedia curvitarsis (Apidae) (33 nests), Hylaeus sp. (Colletidae) (6), Auplopus cf. rufipes (Pompilidae) (5), Trypoxylon sp. (Crabronidae) (4), Pachodynerus nasidens (Vespidae) (3), Auplopus cf. brasiliensis (Pompilidae), Megachile benigna and Megachile sp. (Megachilidae), Euglossa pleosticta, Euglossa sp., and Eufriesea sp. (Apidae) and Penepodium sp. (Sphecidae) all with one nest. Also, four natural enemies were recorded: Chaenotetrastichus neotropicalis (Eulophidae), Gasteruption brachychaetum (Gasteruptiidae), Caenochrysis crotonis (Chrysididae) and Amobia sp. (Diptera: Sarcophagidae). Most bee nests were restrained to the matrix forest and nearby areas, whereas wasps built their nests predominantly in open areas. Regarding seasonality, bees tended to nest in the summer and early autumn influenced by mean temperature, in contrast of wasps that nested in late autumn, winter and spring, influenced by pluviosity. Besides many rare species, which suggests environmental disturbance, the Jardim Botânico do Rio de Janeiro showed a fairly diverse fauna and shows how forest fragment in cities may harbour important representatives of the native fauna.

Abstract The genus Leptodon encompasses two Neotropical raptor species. The more widely-distributed Gray-headed Kite (Leptodon cayanensis) occurs in a vast area of Neotropical region, while the White-collared Kite (Leptodon forbesi) is endemic of the Atlantic Forest of northeastern Brazil, but there are some questions about the extent of its geographic distribution and about its sympatry with its congener. Here we present a review of the geographic distribution and the diagnoses of L. forbesi, correcting recent records based on misidentifications. We also clarify the main features of juvenile and subadult plumage of Leptodon raptors and describe new phases of juvenile plumage.

Abstract Spirobranchus are abundant and diverse serpulids in tropical regions, with three species reported in Brazil, which occurrence is questionable, due to their distant type localities. In the present work, we describe a new species of Spirobranchus from the Brazilian coast and report the other species of the genus occurring off Brazilian shoreline, based on specimens from different locations. Specimens were collected in the states of Alagoas, Rio de Janeiro, and Santa Catarina, sorted and analyzed under a stereoscopic microscope. Then, the animals were anesthetized and subsequently fixed and prepared for the scanning electron microscopy. Specimens from the Caribbean and other Brazilian states were loaned from Museu Nacional of Universidade Federal do Rio de Janeiro, Universidade Estadual do Rio de Janeiro and Universidade Federal de Alagoas. Morphological analyzes differentiated the three species and provided details of the morphology that can be used in the future taxonomy of the family. The species S. giganteus and S. tetraceros are more similar to each other, but can be readily separated based on the spiral radiolar crown in the former; S. minutus differs from the other species for the tube, operculum, and type of uncini. Spirobranchus lirianeae sp. nov. nests within S. kraussii-complex, with a concave operculum, absence of collar chaetae and paired compound eyes on the radioles, differing by being a solitary rather than a gregarious species, by the funnel-shaped operculum, fringed tonguelets and tube with single keel, distally pointed.

Abstract South American racers of the tribe Philodryadini are a widespread and diverse group of Neotropical snakes with a complex taxonomic and systematic history. Recent studies failed to present a robust phylogenetic hypothesis for the tribe, mainly due to incomplete taxon sampling. Here we provide the most extensive molecular phylogenetic analysis of Philodryadini available so far, including 20 species (83% of the known diversity) from which six were not sampled previously. Our results reveal that Philodryadini is not monophyletic, but instead includes a central Andean clade formed by Philodryas simonsii, P. tachymenoides, and P. amaru, and a southern and cis-Andean clade including all remaining philodryadines. This discovery requires resurrection of two genera as well as erection of a new tribe of Xenodontinae for the central Andean clade. Within the southern and cis-Andean radiation, our analyses resolve a basal dichotomy separating two main lineages: Clade A, containing the Common Green Racers P. laticeps and P. viridissima and the South American Vine snakes P. georgeboulengeri and P. argentea; and Clade B, including the remaining species of Philodryas sensu stricto. We resurrect the genera Chlorosoma and Xenoxybelis to better represent the monophyly of lineages within the southern and cis-Andean clade.

Abstract There are few studies dedicated to the natural history of Neotropical spider wasps (Pompilidae). When it comes to urban areas, the knowledge on these wasps is even scarcer. This study sheds light on the natural history of Auplopus cf. rufipes and A. cf. brasiliensis (Hymenoptera: Pompilidae: Ageniellini) from an urban Atlantic Forest fragment in the Jardim Botânico do Rio de Janeiro, Rio de Janeiro City, Brazil. Auplopus cf. rufipes displays a multivoltine pattern and frequently nests in bamboo canes scattered in the open areas, whereas A. cf. brasiliensis is a rare sight, with only a single nest collected from a hose trap-nest. Females of the former species show aggressive behaviour, which suggests a solitary lifestyle. Their nests were partly enveloped in a complex structure, similar to other species that build free-standing, unconcealed nests and display some degree of sociality. Such behaviour could not be observed for A. cf. brasiliensis. Despite that, nests of both species were built using mud pellets, though the brood cells differed regarding arrangement and position in the trap. Two parasites were found attacking the cells: Caenochrysis crotonis (Chrysididae) in a cell of A. cf. rufipes, and Chaenotetrastichus neotropicalis (Eulophidae) in two cells of A. cf. brasiliensis, both recorded for the first time. Auplopus cf. rufipes was found to prey on Frigga cf. quintensis (Salticidae), the first record of this genus as a host of Auplopus.

Abstract The uncertain identity of Hyla x-signata Spix, 1824 has been a pervasive problem in the taxonomy of the genus Scinax. A species supposedly distributed from northeastern Brazil northwards to Colombia and Venezuela, described in a few lines without much information and with an accompanying figure, and its type specimen lost during World War II, combined to produce a curious situation. Twenty-one of the 39 species of the S. ruber Clade described in the last 50 years were considered to require a diagnosis from S. x-signatus by their authors. In most cases these had no other alternative than to gather information about this species from indirect sources, frequently pointing out the problems associated with its uncertain identity. In this paper, we review the taxonomic history of Hyla x-signata, designate a neotype, provide a redescription including advertisement call and sequence data, and diagnose it from all other species of the S. ruber Clade.

Abstract The new bulimulid species, Drymaeus currais sp. nov., is described based on shell and anatomical features. It is endemic of Guapirá Island, belonging to the Currais Archipelago, a small protected area off Paraná coast. The species is thus, based at least on endemicity, endangered. It has as closest species D. castilhensis, another endemic species of Castilho Island, ~70 km northwards. Its main exclusivities are a banded shell (except for periumbilical area); a ureter ~1/3 opened (furrow); an external anus; a slightly different buccal and intestinal arrangement; a penis lacking internal chambers; a small receptacle with a genital appendix.

Abstract Agroforestry systems represent the integration of agricultural crops with native vegetation. These systems are of great importance to minimize the agricultural impact in the land through intercropping of these vegetations. Despite of the importance of Chrysidoidea as parasitoids wasps associated with different groups of insects, there is no study comparing the assemblages of these hymenopterans in conventional and agroforestry systems in southeastern Brazil. The “Pontal do Paranapanema”, located in the extreme west of the state of São Paulo (Brazil), has historically been occupied by coffee crops and some small areas of agroforestry systems. Therefore, this study aimed to verify the abundance and composition of Chrysidoidea wasp fauna in different conventional coffee crops and agroforestry systems located in this region. To do so, we collected in six different localities in the “Pontal do Paranapanema” using a Malaise trap in each locality, with collections occurring monthly between June 2011 and July 2012. A total of 3,623 Chrysidoidea specimens of three families were collected: Bethylidae, with four genera and 3,396 individuals, representing 93.73% of the total collected; Chrysididae with 11 genera and 151 individuals (4.16%), and Dryinidae with five genera and 76 individuals (2.09%). In terms of abundance, the agroforestry was responsible for most of the individuals collected (n = 2029), followed by the conventional systems with 1,406 individuals and the transitional with 188. The most abundant genera were Epyris and Dissomphalus, responsible for about 92% of the total of Chrysidoidea collected. Most of the genera of Chrysididae were collected in the conventional systems alone or in both conventional and agroforestry systems. For Bethylidae and Dryinidae, no genera were found exclusively in the conventional system. It is expected that the structural complexity of each one of the different ecosystems impact directly in the fauna of Chrysidoidea parasitoids associated.

Abstract Specimens of the rare amphi-Atlantic epitoniid Opaliopsis atlantis have been recorded in the Strait of Messina (central Mediterranean) from a hydrozoan stylasterid-rich habitat. The record, which adds a new site to the sporadic occurrences of this prevalently deep-water species, may be considered the first contextualized report from Mediterranean Sea. Opaliopsis atlantis displays a planktotrophic larval development functional for long-range colonization of favorable habitats. Its discontinuous distribution all over its broad geographic range highlights the potential role of Atlantic seamounts as stepping-stones for transoceanic dispersal. Although no conclusive information is yet available upon the feeding requirements of O. atlantis all over its range, we suggest that this cnidarian-ectoparasitic prosobranch could adapt to different hosts, as a strategy that may enhance its wide biogeographic distribution.

Abstract The Gray-hooded Gull (Chroicocephalus cirrocephalus) is a seabird distributed in almost all South American countries. However, breeding information on the species in Brazil is scarce. In this study, a literature review and searches in online databases (WikiAves and eBird) were carried out to gather breeding information on the species in the country and new records of nests of the Gray-hooded Gull were registered on the northern coast of the Rio de Janeiro state. Literature review indicated breeding records in Rio Grande do Sul, Rio de Janeiro and Rio Grande do Norte states. On WikiAves, 19 records of the species with nests, eggs, chicks and breeding colonies were reported between 2009 and 2020, in Macau, Rio Grande do Norte and one adult hatching at Rio Grande do Sul. In August 2019, two nests were recorded at Ubatuba lagoon (22°09′S and 41°18′W) in the Restinga de Jurubatiba National Park, in the Quissamã municipality in Rio de Janeiro. The nests were described and monitored during five weeks. Each nest contained two eggs and was built with the grass Paspalum vaginatum. Over time, the eggs were degraded and disappeared from the nests, without signs of hatching and possible predation. This study compiles for the first time all the breeding information on the species in Brazil and contributes with data about nests and egg biometry.

Abstract Local fauna inventories provide primary key information on diversity and distribution of species for conservation purposes. The Atlantic Forest holds 50% of anuran species in the country and the main threats to the conservation of this fauna are habitat reduction and fragmentation. The present study brings information on the local richness and species composition of four anuran taxocenoses from the subtropical Atlantic Forest of Paraná and Santa Catarina states, Brazil. Data collection included breeding sites surveys (N = 56) and literature review. Richness and beta diversity were compared through rarefaction/extrapolation curves, local contribution to beta diversity (LCBD), beta partitioning and cluster analysis. Anuran from 46 species were registered and local richness differences were observed on the rarefaction/extrapolation curves and on asymptotic analysis. Nevertheless, the LCBD did not detect differences in species composition among the four taxocenoses. The turnover was the predominant component of beta diversity. The geographical distances explain species composition for all localities compiled in this study. The differences among local richness may be related to environmental impacts, emphasizing the need for conservation of biodiversity in the remnants of Atlantic forest.

Abstract The Indo-Pacific edible swimming crab Scylla serrata is reported here for the fifth time from the western Atlantic including a failed attempt of introduction to Florida for aquaculture purposes in the years 1960’s. The species had been recorded from Brazil in the early 1980’s and in 2011 and from the Caribbean coast of Colombia in 2013. The capture of a third specimen in southeastern Brazil on 24 August 2020 is discussed here. On all occasions individuals found in Brazil were adults captured alive near port areas. The occurrence of S. serrata in disparate time periods in the western Atlantic (1983, 2011, 2013 and 2020) is regarded as an indication of low inoculation pressure.

Abstract Recent findings of ommatids from mid-Cretaceous Burmese amber have greatly increased our knowledge on the Mesozoic diversity of Ommatidae. Here, we report the first distinctly miniaturized ommatid species, Miniomma chenkuni gen. et sp. nov., entombed in mid-Cretaceous amber from northern Myanmar. This new fossil species is characterized by its small body size (less than 2 mm long) and subglobular metacoxae. Our discovery of miniaturization in extinct Ommatidae suggests a high ecological diversity of this family in the Mesozoic.
