Abstract in English:Abstract The humpback whale (Megaptera novaeangliae) is distributed among most oceans and seas of the globe (except Mediterranean Sea). These whales migrate from feeding regions in the Antarctic waters to breeding areas in tropical and subtropical seas. Here we report the stranding of a female young humpback whale, which was founded dead in the vicinity of the Talavera Island, in the Paraná River Delta, Buenos Aires Province, Argentina. From the analysis of mitochondrial cytochrome c oxidase subunit I gene sequences, two novel haplotypes were found, totalizing four haplotypes described for the species. In the La Plata River Basin this species was found only twice at the end of the XIX century. Thus, the new finding constitutes an important addition to the list of cetaceans that occurs in Uruguay, Paraná and La Plata Rivers.
Abstract in English:Abstract Some aspects of reproduction in two species of Mimagoniates, M. microlepis (Steindachner 1877) and M. rheocharis Menezes & Weitzman 1990 are herein described. Samples were taken monthly from January 1998 to February 1999 in two streams in the locality of Maquiné, Rio Grande do Sul, Brazil. Results from the analysis of hundreds of specimens of M. microlepis and M. rheocharis in two investigated sites indicated mature specimens and peaks of the gonadosomatic index (GSI) along the year. There was a negative and significant correlation between M. microlepis male’s GSI and water temperature. Females of the latter species and both sexes of M. rheocharis, in turn, showed no correlation with any of the tested parameters (relative stomach weight, day length, rainfall). Absolute and relative fecundity are lower than in externally fertilized species of Characidae. Maximum oocyte length was 1.14 mm for M. microlepis and 1.02 mm for M. rheocharis and both species were characterized as total spawners based on the type of oocyte development estimated through oocyte size analysis. Features like non-seasonal reproductive period, low fecundity, and insemination may indicate adaptive advantages, which may enhance the chance of survival even with low energetic investment and improved fertilization.
Abstract in English:Abstract We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data.
Abstract in English:Abstract In this study we perform an inventory of the insect galls in savanna and forest sites of Hidrolândia, Goiás, Brazil. We found 150 insect gall morphotypes, distributed on 39 botanical families and 104 plant species. Among the insect galls, 81 gall morphotypes were recorded in the savanna site and 73 in the forest site. The plant taxa richest in insect galls were the family Fabaceae with 22 gall morphotypes, the genus Bauhinia (Fabaceae) with 15, and the species Siparuna guianensis (Siparunaceae) with seven gall morphotypes. We found gall-inducing insects belonging to orders Diptera, Coleoptera, Lepidoptera and Thysanoptera. The galling insects of family Cecidomyiidae (Diptera) were the most common inducing 48.1% of the gall morphotypes. This is the first systematic survey of insect galls realized in the city of Hidrolândia, being this the site with the higher insect gall diversity already cataloged to the Central region of Brazil.
Abstract in English:Abstract. The amphibian fauna of the state of Rio de Janeiro, in southeatern Brazil, is characterized by high species richness and rates of endemism, and is still insufficiently known. A first list of amphibian species with occurrence in the state was published in 2004 and reported 166 taxa, but since then many new records, descriptions of new taxa, and revalidations and synonymizations of species have consistently improved the knowledge about the state’s amphibian biodiversity. Thus, a review and update of that list was deemed necessary. We herein present an updated and commented list of amphibian species occurring in the state of Rio de Janeiro based on a survey of the literature. We recorded the occurrence of a total of 201 species of amphibians (197 anurans and four caecilians) in Rio de Janeiro, with 54 of them (ca. 27%) considered to be endemic of the state. Our study presents an increase in species richness of 21% since the publication of the previous list, indicating a consistent advance in knowledge of the composition of the amphibian fauna in the state. In spite of its relatively small territorial extension (total area ca. 43,800 km²), the state of Rio de Janeiro contains nearly 20% of the amphibian species known to occur in Brazil and around 40% of those occurring in the Atlantic Forest biome. Thus, that state constitutes an important reservoir of amphibian biodiversity in the Atlantic Forest biome and in Brazil, as a whole.
Abstract in English:Abstract A checklist of the family Chelodesmidae Cook, 1895 (order Polydesmida) from state of São Paulo, Brazil has been performed based on literature and examined material from the collection of the Instituto Butantan, São Paulo (IBSP). A total of 15 genera (7 tribes and 5 genera considered incertae sedis) with 64 species are listed. Among these species, 30 presented a single one record in the state, 19 with more than one record and four recorded for the first time for the state of São Paulo, and 11 species occurring in other Brazilian states. The most distributed species is Brasilodesmus paulistus paulistus (Brölemann, 1902) with 52 records of occurrence. In addition, a complete bibliography list of the chelodesmidan fauna from the state is compiled, as well as distribution maps for all species are provided.
Abstract in English:Abstract Specific and efficient methods for capturing tinamous are scarce in the scientific literature. Here we tested the effectivity of two methods for capturing the Yellow-legged Tinamou Crypturellus noctivagus (Tinamidae): a bell-trap adapted with a nylon cast net and a type of fall-trap. In a forest remnant in Rio Grande do Sul state, Brazil, we applied 120 hours of sampling effort using the traps, resulting in the capture of six individuals (two females and four males). These capture methods are an efficient tools and useful for forest tinamous studies, although it can be also used for capturing other forest bird which use the forest floor.
Abstract in English:Abstract The morphology of the fifth pereiopods was studied under scanning electron microscopy in ten species of porcelain crabs for chaetotaxy and setal diversity, namelly Megalobrachium pacificum, Megalobrachium roseum, Pachycheles grossimanus, Petrolisthes armatus, Petrolisthes tuberculatus, Pisidia brasiliensis, Pisidia longicornis, Polyonyx gibbesi, Porcellana platycheles and Porcellana sayana. Six setal types were identified: simple, pappose, sickle-shaped serrate, straight serrate, club-shaped and tooth-like cuspidate. Porcelain crabs can differ in the fifth pereiopod setal morphology, chaetotaxy and setal density, even among species within the same genus. The absence of sexual dimorphism of the grooming legs in porcelain crabs suggests that grooming eggs requires no particular grooming apparatus in females and that male and female are equal in grooming efficiency.
Abstract in English:Abstract Parasitoids manipulate the host metabolism for their own benefit by influencing its development and the direct or indirect result of it is the host death. This study aimed to observe the influence of parasitoidism of Paravilla sp. (Diptera, Bombyliidae) on the development of antlion larvae Myrmeleon brasiliensis (Návas, 1914) (Neuroptera, Myrmeleontidae). The specific objectives were to verify in which larval instars the parasitoid oviposition occurs, the influence of the parasitoid on the larval and pupal development time of M. brasiliensis, the differences in body length of the antlion larvae, as well as of the sex ratio of M. brasiliensis adults. For this, the larvae were differentiated in 1st, 2nd and 3rd instar and measures on body length (head-abdomen) and accompanied until the emergence of the adult. It was observed that the parasitoid Paravilla sp. attacked only the 2nd and 3rd instar larvae. The parasitoid Paravilla sp. oviposited only in 2nd and 3rd instars larvae. No significant differences were observed on larval development time, in the larval body length and in the adult sex ratio between groups of parasitized and non-parasitized M. brasiliensis larvae, however, was observed differences in the pupal development time of these two groups. Thus, we can conclude that the parasitoid Paravilla sp. influences the development time of M. brasiliensis pupal.
Abstract in English:Abstract We report the first record of the Choco broad-nosed bat (Plathyrrhinus chocoensis Alberico & Velazco, 1991) in Santo Domingo de los Tsáchilas province in northwestern Ecuador. This voucher specimen represents the southernmost record of the species and expands its distribution ca. 120 km south. The animal was caught at a farm, specifically in a live fence consisting of several tree species. Preservation of bat species occurring in agricultural landscapes requires local policies and environmental education.
Abstract in English:Abstract A review of Enaphalodes Haldeman, 1847 is presented. Descriptions of four new species of Enaphalodes are included: E. antonkozlovi, sp. nov. from Costa Rica, E. bingkirki, sp. nov. from Nicaragua, E. monzoni, sp. nov. from Guatemala, and E. cunninghami, sp. nov. from Mexico. Enaphalodes senex (Bates, 1884) is revalidated and it is newly recorded from Nicaragua and Guatemala. A key to the 15 currently recognized species of Enaphalodes is included.
Abstract in English:Abstract Despite the large number of studies investigating ant diversity in Brazilian biomes, no ant-related studies have been carried out in Campos Gerais, a grassland physiognomy in Paraná state. The present study is the first inventory of the ant fauna in one of the few conservation units protecting the Campos Gerais landscape, the Guartelá State Park (PEG). Sixty samples were collected from different habitats within PEG using pitfall traps. Qualitative samples of leaf litter were collected from forest fragments and submitted to Winkler extractors. In addition, manual qualitative sampling was carried out in the various physiognomies within the PEG. A total of 163 species was collected and sorted into 43 genera and nine subfamilies. Five genera and 28 species were recorded for the first time in the state of Paraná. Out of these, 17 species were also recorded for the first time in the Southern Region of Brazil and two were recorded for the first time to the country. The significant species richness in the PEG and the high number of new records is a strong sign of this ecosystem’s potential to reveal taxonomic novelties. These results suggest that PEG, and the Campos Gerais as a whole, should be the target of greater conservation efforts to preserve native remnants.

Abstract in English:Abstract Cerrado dry forest enclaves have been treated as an endemic bird area. In the last years, some avifaunal surveys have been conducted in dry forests on the left bank of the São Francisco River, eastern Brazil. Nevertheless, there is a gap of detailed ornithological surveys in the Cerrado dry forest enclaves on the right bank of this river. Here, we present the first avifaunal survey of a Cerrado dry forest enclave on the right bank of the São Francisco River. The study area, named “Curral de Pedras”, comprises a dry forest enclave and other associated habitats in central Minas Gerais state, southeastern Brazil. We recorded 172 bird species; nine taxa have their ranges strongly associated to the Caatinga; six present their ranges associated to the Atlantic Forest and one is typical of the Cerrado. Important records are those of Campylopterus calcirupicola, a recently described species associated with dry forests of central Brazil, and Celeus ochraceus, collected in its southernmost range. Furthermore, we obtained specimens that present intermediate phenotypes between the following woodcreeper species: Lepidocolaptes squamatus / L. wagleri and Xiphocolaptes albicollis / X. falcirostris. Those records reinforce the need of further sampling and collecting activities in those dry forest enclaves aiming future researches in taxonomy, geographic variation, and phylogeography.
Abstract in English:Abstract Forest fragments in urban areas have many habitat resources that frogs use for refuge, reproduction and growth. Knowledge of an anuran assembly is the first step towards understanding the importance of these forest fragments in areas highly threatened by anthropogenic actions. We sampled anurans during the day and night from November 2012 to August 2013 through visual and acoustic surveys. We found 333 individuals belonging to 19 species. The highest richness and abundance were recorded in January whereas the lowest richness and abundance were recorded in June. Most species were found in open areas. Our results highlight the importance of well-studied urban fragments for the anuran community. The conservation of these habitats may ensure the viability of the ecological functions of this anuran community for the future.
Abstract in English:Abstract Two new records of gynandromorphs in Xylocopa Latreille, 1802 (Hymenoptera, Apidae). Gynandromorphs are deviant morphological individuals with genetically distinct male and female tissues. Records of sex anomalies seems to be important to better understand the mechanisms regulating phenotypic expression. Herein, two new cases of gynandromorphs in carpenter bee species of Xylocopa from Brazil are described and figured: a mixed gynandromorph of the X. (Neoxylocopa) brasilianorum (Linnaeus, 1767) from São Paulo and a bilateral gynandromorph of the X. (Neoxylocopa) ordinaria Smith, 1874 from Sergipe.
Abstract in English:Abstract The genus Jupoata is redescribed and Jupoata antonkozlovi, a new species from Costa Rica is described. An updated key to species of the genus and a new geographical record are provided.
Abstract in English:Abstract Loneuroides is registered for the first time in Brazil. A new species from the Brazilian state of Bahia, is here described and illustrated. It differs from all the other species in the genus in details of the female ninth sternum and by number of primary branches in vein M of fore- and hind- wings. A map with the distribution of the species of Loneuroides is included.
Abstract in English:Abstract Heterelmis Sharp, 1882, comprises 22 species and subspecies with 3 species assigned to Brazil so far. Here the forth species, Heterelmis debilis sp. nov. from Brazil, is described and illustrated. The type material is deposited in the Museum of Zoology of the University of São Paulo, São Paulo, Brazil (MZSP) and Natural History Museum, London, UK (NHMUK). Additionally, an identification key with distributional data for Brazilian species is proposed.
Abstract in English:Abstract Triplocania umbrataoides sp. nov., from the Río Tambopata Reserved Zone, in Madre de Dios, Peru, is here described and illustrated. Triplocania magnifica Roesler and the male of Triplocania spinosa Mockford are redescribed and illustrated. The female Triplocania spinosa is here described and illustrated. The original combination of Belicania cervantesi (García Aldrete) is revalidated.
Abstract in English:Abstract Herein, we present the first record of the nymph of Nanomis rasmusseni Chacón, Pescador & Segnini, 2013, from two biogeographic regions in Colombia. This species was originally described for the Venezuelan Andes. Both Colombian and Venezuelan populations occur at high elevations, in streams with similar altitudes. We also found that both populations can be distinguished from each other by the terga II, VII, and IX coloration, in addition to the branching pattern of the abdominal gills.
Abstract in English:Abstract Arene lychee sp. nov. is described from Canopus Bank, a seamount located ~190 km off Fortaleza, Ceará, NE Brazil (02°14’25”S, 38°22’50”W), based on shell morphology. The species is characterized by a large, trochiform shell; color ranging from intense reddish to white (darker on spiral cords, lighter at base) with a yellow apex; sculpture of 3-8 wide spiral cords with large scale-like spines; cords separated by deep interspaces with similar width, and interspaces sculptured by closely-packed, thin axial growth lines.
Abstract in English:Abstract Insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). Galls are changes in the pattern of growth and development of plant tissues or organs in response to the action of an inducing organism, usually an insect. The goal of the present study was to inventory the insect galls of the Floresta da Cicuta (Volta Redonda, RJ, Brazil). The collections were carried out along all the trails, totaling 16 hours of sampling. Forty-three morphotypes of insect galls were found in 24 plant species (18 genera and 15 families). Sapindaceae and Euphorbiaceae were the most richness host plant families. Six new records of host plant species are presented: Senefeldera verticillata (Vell.) Croizat. (Euphorbiaceae), Inga acuminata (Fabaceae), Ocotea elegans (Lauraceae), Ouratea stipulata (Ochnaceae), Psychotria nuda (Rubiaceae) and Cestrum intermedium (Solanaceae). Most of the galls occurred on leaves (n = 21) and stems (n = 18), followed by buds (n = 2), two gall morphotypes occurred simultaneously on leaves and stems. One-chambered galls were more frequent (n = 31), as well as glabrous galls (n = 33). The gallers belong to three insect orders: Diptera (Cecidomyiidae), Hemiptera, and Lepidoptera. The associated fauna comprised parasitoids (Hymenoptera), inquilines (Hemiptera and Coleoptera) and successors (Isoptera and Acari).
Abstract in English:Abstract Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork and on secondary data (from institutional collections and from the literature). We report the occurrence at Ilha Grande of a total of 74 species, being 34 amphibians (all of them anurans) and 40 reptiles (27 snakes, 11 lizards, one amphisbaenian and one crocodylian). Our survey added 14 species to the herpetofaunal list of Ilha Grande (three of amphibians and eleven of reptiles) and removed one species (the amphibian Cycloramphus fuliginosus) from the previous list. The data indicated that Ilha Grande houses a considerable portion of the Atlantic Forest amphibian and reptile diversity (ca. 6% and 19%, respectively, of the species occurring in this biome) together with high occurrence of species endemic to this biome plus a few amphibian species endemic to this island. Ilha Grande is thus an important reservoir of both biodiversity and endemism of amphibians and reptiles of the Atlantic Forest of Brazil, which highlights the importance of the conservation of the island and of its different habitats along the insular landscape.
Abstract in English:Abstract Muscidae (Diptera) comprises one of the most important taxa in medical, veterinary and forensic entomology, especially due to their association with decomposing carcasses and cadavers. Yet, knowledge on their distribution and behaviour is still incipient in several biomes, which is the case of dry tropical forests. This study aimed to evaluate the attractiveness of different organic substrates to species of Muscidae in areas of seasonally dry forests (Caatinga) in Northern Brazil. Sampling was carried out in five Caatinga areas between 2015 and 2017, using suspended traps baited with bovine spleen, fish or human faeces. When all samplings were combined, 3,176 adults of nine species were collected. The assemblages of muscids had higher richness and abundances on bovine spleen, which attracted 66% of all specimens, when compared to the other substrates. Musca domestica was the most abundant species, and it was dominant in assemblages associated with spleen and fish. Assemblages attracted to spleen and fish had higher similarity, differing from those associated with faeces. Differences in food attractiveness are presented for species of medical interest as pathogen vectors (e.g., Synthesiomyia nudiseta (Wulp, 1883)) and of forensic relevance as colonizers of human corpses (e.g., Ophyra aenescens (Wiedemann, 1830)).
Abstract in English:Abstract Following a recommendation of the International Code of Zoological Nomenclature, this paper provides a catalogue of the type specimens of Bibionidae (Diptera: Bibionomorpha) held in the collection of the Museu de Zoologia da Universidade de São Paulo, Brazil (MZUSP). Label data and the condition of 21 type specimens (two holotypes and 19 paratypes) of two Neotropical species is provided. Photographs of the male terminalia of the holotypes are also presented.
Abstract in English:Abstract Pantophthalmus pictus (Wiedemann, 1821) (Diptera, Pantophthalmidae) has been reported to occur in south and southeastern Brazil, Paraguay and Argentina. Here we report the first occurrence of these rare flies in the Cerrado vegetation of central Brazil. We also provide an updated list of the geographical distribution of the 20 species of the genus Opetiops Enderlein, 1921 (1 species) and Pantophthalmus Thunberg, 1919 (19 species) in the Neotropical region.
Abstract in English:Abstract Over the last few decades, the systematics and evolution of carcharodontosaurids, a group of large predatory dinosaurs, from North Africa have been better understood mainly due the discovery of new species. We review this record here and discuss its importance for understanding the evolution and ecology of these dinosaurs. North Africa has one of the best records of carcharodontosaurid species. These species show dietary specializations and paleogeographic distributions similar to other top predatory theropods such as Abelisauridae and Spinosauridae. However, carcharodontosaurids have a wider distribution than other large theropods. The middle Cretaceous of North Africa was characterized by the niche overlap between large predators. This evidence increases our understanding of the evolution of Carcharodontosauridae in a highly competitive region, a conjuncture rarely reported for large top predators.
Abstract in English:Abstract Coastal lagoons and their surrounding habitats often harbour high biodiversity and some of the most threatened ecosystems in the world. However, in the Neotropics the biodiversity is often poorly described, lacking even inventories of species which therefore limits the assessment of threats and the stablishment of efficient conservation measures. We present here lists of bird species recorded at ten sites along the under-studied coastal lagoons of southern Santa Catarina, Brazil, collected mainly from October 2012 to March 2018. We present quantitative data for endemic and threatened species, identify migratory status and highlight distributional novelties. In total, we recorded 229 species encompassing 63 families, including twelve species of conservation concern, 11 endemic to the Atlantic Forest or Pampas zoogeographical provinces and 38 migrants. We provide new records of seven rare species in Santa Catarina (Larus atlanticus, Calidris pusilla, Aramides ypecaha, Bubo virginianus, Limnornis curvirostris, Phacellodomus ferrugineigula and Pseudocolopteryx flaviventris) and report the first evidence of occurrence of Schoeniophylax phryganophilus for the State. Based on our findings, we discuss the regional diversity and conservation of the avifauna.
Abstract in English:Abstract Helicina variabilis Wagner, 1827 (Neritimorpha, Helicinidae) is redescribed based on a sample collected in Nanuque, northern Minas Gerais, Brazil. The species description, previously based only on the shell, is expanded to the phenotypic features. The study revealed absorption of the internal shell whorls; a diaphragm muscle connected to the floor of the pallial cavity; a monoaulic pallial oviduct, with the female genital aperture inside the anal aperture, and the lack of a seminal receptacle and provaginal sac; and the pleural ganglia of the nerve ring connected with each other. The significance of these findings is discussed in the light of current taxonomic and phylogenetic knowledge.
Abstract in English:Abstract Museu Paraense Emilio Goeldi (MPEG), situated at Brazilian state of Pará, houses the third largest South-American mammal scientific collection, being a primary source of information for the study of Amazonian and Neotropical mammalians. The collection holds 245 felid specimens, comprising 210 skulls, 53 skins, 10 skeletons, and two anatomical pieces, representing 90% of wild Brazilian cat species, mainly from localities of Northern Brazil. We presented a list of this material, indexed by the genera and species. We also provided craniodental measurements of all the specimens with skull, and comment on the conservation status of the species and other remarkable data, including the first record of Leopardus tigrinus in the Brazilian state of Rondônia.
Abstract in English:Abstract The first systematic studies on insect galls in Brazil date to the early 20th century, after which research on insect galls remained dormant in the country, with interest not reviving until the 1980s. The aim of this study was is to document historical trends in publications about insect galls in Brazil over the last 30 years. Papers about insect galls and galling species in Brazil published in peer-reviewed journals from 1988 to 2017 were compiled. A total of 1,378 papers were analyzed, of which 182 addressed insect galls in Brazil. The results showed that the number of publications on the subject has been increasing over the last 30 years, and especially in the last decade. The diversity of journals that published on the subject has also been increasing. The studies were concentrated on the following topics: ecology (94 papers), inventory (29) and taxonomy (27). Most of the insect gall inventories in Brazil took place in the Southeast Region (29 papers), followed by the Central-West and Northeast regions, with eight papers each. This study documents a trend toward increasing scientific production on insect galls in Brazil, but with significant geographical bias: the researchers involved are concentrated in the Southeast Brazilian region.

The genus is recorded for the first time for Goiás State. Additions and modifications in the previously published key to Brazilian species are provided.
Abstract in English:Abstract Glyptoscapus letiziae, a new species of Hexoplonini Martins, 2006, is described from Brazil (Minas Gerais). Glyptoscapus cicatricosus Aurivillius, 1899 and G. vanettii Martins, 1959 are synonymized with G. pallidulus (White, 1855). A key to species of Glyptoscapus is provided. New state records are presented for Thoracibidion io (Thomson, 1867) (Neoibidionini), Coleoxestia rafaeli Santos-Silva & Wappes, 2017 and C. denticornis (Gahan, 1892) (Cerambycini). The female of C. rafaeli is described for the first time.
Abstract in English:Abstract This paper describes and illustrates Trichomyia muiraquita Araújo & Bravo sp. nov. from the state of Amazonas, Brazil. Furthermore, with the aid of a scanning electron microscope and light microscope, we report for the first time the presence of two small sensilla in flagellomeres of the Trichomyia species.
Abstract in English:Abstract Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985 and 2015, we searched for documents in the ISI Web of Science, Scopus and SciELO databases. A total of 979 works were evaluated from 184 periodicals. The United States is the country with the most publications about aquatic oligochaetes, followed by France, Germany and Italy. Works related to the ecology and ecotoxicology of these organisms are most abundant. Studies carried out in the laboratory are most frequent, consisting of investigations involving bioassays, morphology, genetics and molecular biology. The results also show that spring, cave water bodies and swamps have been studied less than any other aquatic habitat and that countries of the Southern Hemisphere are under-represented in the studies of aquatic oligochaetes. Hence, there is a need for increased efforts to fill in gaps in the knowledge about these oligochaetes.
Abstract in English:Abstract The Hymenoptera collection of the Museu de Zoologia da Universidade de São Paulo, Brazil (MZSP) houses one of the most important collections for the Brazilian and Neotropical wasp faunas. The present catalogue lists the type specimens of Pompiloidea, Thynnoidea and Vespoidea (Insecta, Hymenoptera) deposited in the MZSP. The collection includes a total of 422 type specimens (66 holotypes, 28 lectotypes, 278 paratypes, 45 paralectotypes, and five syntypes), being 91 Pompiloidea (40 Mutillidae type specimens of 10 genera and 25 species, 51 Pompilidae type specimens of 4 genera and 27 species), 191 Vespoidea (15 genera and 86 species of Vespidae), and 18 Thynnoidea (eight genera and 12 species of Thynnidae). All information written in labels was compiled and is presented along with additional data from the original descriptions, MZSP records and other sources. We provide Specimage links to high-resolution photographs of holotypes and lectotypes at the Hymenoptera image database of the Ohio State University.
Abstract in English:Abstract The state of Mato Grosso is the 3rd largest Brazilian state, is covered with three major Brazilian biomes, including the Pantanal, Cerrado, and Amazonia. To date, 449 ant species are recorded in literature for the state. In the present work, we documented the ants sampled along a fragmented landscape, in the municipality of Juara, in the Cerrado-Amazon transition zone in the state of Mato Grosso, Brazil. The ant species were captured with Pitfall traps installed in 20 trails with 10 traps in each (totaling 200). Our results show 151 species, belonging to 43 genera and eight subfamilies, of which 28 species were recorded for the first time in the state and five species recorded for the first time in Brazil. Most genera collected were Pheidole Westwood, 1839 (45 species) followed by Crematogaster Lund, 1831 (11 species). By highlighting species recorded for the first time in state of Mato Grosso and Brazil, we hope to encourage new discoveries and increase the general knowledge of the ant fauna of different biomes in the region.

Abstract in English:Abstract The brain gross morphology of Rhamdia quelen is described and compared with seven species of six genera of Heptapteridae. Interspecific variation in shape, size, and position of brain subdivisions was observed in all examined species. The posterior position of the hypophysis on the hypothalamus and presence of a lateral subdivision on the lobus facialis are shared by all examined heptapterids. Rhamdia quelen and Pimelodella gracilis, currently considered closely related within the family Heptapteridae, exhibit the anterior and posterior area of the telencephalon with equivalent widths, and the lateral line lobe reaching the anterior area of the lobus vagi. Members of the so called Nemuroglanis sub-clade (Cetopsorhamdia iheringi, Heptapterus mustelinus, Imparfinis mirini, and Phenacorhamdia tenebrosa) share the lobus vagi proportional smaller than the lobus facialis; the lateral line lobe reaching the half length of the lobus facialis; the tectum mesencephali in contact with the telencephalon, and thinner anterior area of the telencephalon. The results reveal several features that are phylogenetically informative among the heptapterids examined, and corroborate previous hypotheses based on other non-neural anatomical characters.
Abstract in English:Abstract The unknown female of Brasineura diamantina Silva-Neto & García Aldrete is described and illustrated, with new records and comments on variation in the fore-hindwing venation, based on 27 females and 113 males collected in five localities in the Chapada Diamantina, Bahia, Brazil. Thirty four types of variation and anomalies in the fore-hindwing veins were found. A revised diagnosis of B. diamantina is also presented.
Abstract in English:Abstract Osteologic collections are used as an aid to scientific and teaching activities, to provide information on specific vertebrate characteristics, such as body support, posture, mode of locomotion, feeding habits and ecological niche. Known techniques for cleaning entire skeletons or mammalian skulls vary according to the destination of the material, the objective of the study, the taxonomic group, and the size of the specimen. The objective of this study was to test three different methods of maceration for cleaning bat skulls (traditional biological maceration, controlled biological maceration using Dermestes maculatus and controlled biological maceration using necrophagous fly larvae). The methods were carried out during five consecutive months, and the minimum and maximum times taken by each method were recorded and documented. Cleaning by fly larvae was the least costly method; the whole process was carried out during the preparation of the osteologic material. The flies ovulated directly on the pieces and the time spent was relatively short. Cleaning by dermestid larvae also resulted in clean parts in a short period, however, its culture needs specific maintenance conditions, since the size of the colony oscillates according to environmental temperature.
Abstract in English:Abstract Studies on fecundity and embryo size have been frequently used to infer about the reproductive potential, embryogenesis, and the energy investment in embryo production in crustaceans. These parameters are relevant to the knowledge of life-history and diversity of reproductive strategies developed by this group. This study addressed the embryo production by the estuarine shrimp Salmoneus carvachoiAnker, 2007, a poorly known caridean shrimp. We investigated whether there was (1) a correlation between fecundity and carapace length, (2) an increase in embryo volume along the embryonic development, and (3) loss of embryos along development. In addition, we investigated whether the esternite length and height and width of the pleura of the second abdominal somite were good predictors of fecundity. A total of 53 embryo-carrying individuals were collected in December 2016 and February 2017 in a tidal mudflat from the estuary of the Paripe River, Ilha de Itamaracá, Pernambuco, Brazil. The carapace length ranged from 3.23 to 4.64 mm (3.78 ± 0.26 mm). Among those, 25 individuals had embryos in initial stage, 5 in intermediate stage and 15 in final stage. Fecundity ranged from 14 to 67 (33.65 ± 12.51 embryos) and was weakly correlated with carapace length. However, fecundity was strongly correlated with the width of the second sternite and width of the pleura of the second abdominal somite. Embryo volume increased markedly (93%) from the initial to the final stage of development. This increase might be due to water uptake to facilitate the membrane rupture at the onset of larvae hatching. There was significant loss of embryos only between the initial and intermediate stage. Future studies on the embryo production by other species of Salmoneus Holthuis, 1955 are necessary to understand and compare these aspects of reproductive biology.

Abstract in English:Abstract The Neotropical species of Curtonotidae are updated and catalogued. A total of 33 species names are listed, including two fossil taxa and one nomem dubium. Valid and invalid names and synonyms are presented, totaling 45 names. Bibliographic references are given to all listed species, including information about name, author, year of publication, page number, type species and type locality. Lectotype and paralectotypes are designated to Curtonotum punctithorax (Fischer, 1933). Curtonotum simplex Schiner, 1868 stat. rev. is recognized as a valid name.
Abstract in English:Abstract Specimens of Pegantha laevis H.B. Bigelow, 1909 and Pegantha triloba Haeckel, 1879 were found in oceanic waters off the northern Brazilian coast. The former species is clearly distinct due to the thickness and shape of peripheral channels, while the latter is recognized mainly due to the exumbrellar furrows and long otoporpae. This study represents the first actual record of P. laevis inside the Brazilian Economic Exclusive zone, since previous reports were far away from the coast, and clarifies the presence of P. triloba off Brazil.
Abstract in English:Abstract Many gall-inducing insects have been reported as pests in the Old World and North America, although few such examples are known from South America. A list of gall-inducing insects of potential economic importance, with a focus on those of restinga environments, was compiled using Maia (2013a) as starting point and updated with the database “Thompson ISI”, using ‘Insect (title) and gall (topic)’ as keywords. Botanical names were updated using the site “Flora do Brasil, 2020”, while potential economic significance of host plant species was acquired from Santos et al. (2009) and the site “Useful Tropical Plants”. Fifty-eight galling species were associated with 29 economically important plant species of 18 families in Brazilian restingas. The gallers were found to belong to Diptera (Cecidomyiidae and Agromyzidae) and Hemiptera (Eriococcidae and Psyllidae), among which Cecidomyiidae were the most important, with 55 gall-inducing species distributed among 28 genera. Six of the found genera are endemic to the Atlantic Forest and, until now, have been exclusively reported in restingas. About 78% of the gallers have been recorded only in Southeast Brazil and about 64% only in the state of Rio de Janeiro. Most gallers were found to be mainly associated with edible and/or medicinal plant species. Data on natural enemies are scarce with most records having been published at the taxonomic level of family or genus. Natural enemies were found associated with 43 gall-inducing species and included parasitoids, predators and inquilines. The first were the most diverse, being represented by 13 hymenopteran families, but the impacts of all of these guilds on galler populations are poorly known. Although 58 gall-inducing species were identified in the present study, the number of insect galls associated with plants of economic interests in restinga environments is about three times greater, since a total of 186 gall morphotypes have been reported. Nonetheless, many gallers are still undetermined, thus revealing how deficient their taxonomical knowledge remains.
Abstract in English:ABSTRACT Studies in remnants of semi-deciduous seasonal forest of the Cerrado are needed to fill sampling gaps and improve basic knowledge of biodiversity. This study presents data on the herpetofauna of Parque Estadual Altamiro de Moura Pacheco, one of the last protected areas of seasonal forest in the core region of the Brazilian Cerrado. Fourteen sites were sampled between March 2007 and April 2008 using pitfall traps and active searches. A total of 35 anuran species were recorded, most of which were found in hygrophilous environments near forest fragments, open areas and riparian or gallery forest. A total of 29 reptile species were recorded, most of which were found in semi-deciduous forest and riparian or gallery forest. Fourteen of the amphibians and five of the reptiles are endemic to the Cerrado. The richness of amphibians and reptiles found in Parque Estadual Altamiro de Moura Pacheco is regionally representative, with communities typical of forest environments.

Additionally, we present new records of Trichomyia (Brachiotrichoyia) armata Barretto, 1954, Trichomyia (Brachiotrichoyia) quatei Bravo, 2001, Trichomyia (Brachiotrichoyia) inermis Barreto, 1954, and Trichomyia (Brachiotrichoyia) plumata Bravo & Araújo, 2013 in Brazil. An identification key for males of the subgenus was updated to include the three new species.
Abstract in English:Abstract A new species, Asphondylia cipo sp. nov. (Diptera: Cecidomyiidae) causing stem and petiole galls on Lessingianthus warmingianus (Baker) H. Rob. (Asteraceae) is described and illustrated from Serra do Cipó, Minas Gerais State, Brazil. A key is provided to separate species of this genus associated with host plants in the Asteraceae family from the Neotropical region.
Abstract in English:Abstract A systematic review of the Neotropical Lauxaniidae genus Neopachycerina Malloch, 1933 is presented. The genus is characterized mainly based on some features of the head, like the anterior pair of fronto-orbital setae conspicuously shorter than posterior one and rather close to them; face with a distinct elevation between antennal bases; antenna slightly elongate, first flagellomere tapered to tip and about three times as long as its basal width, arista thickened by dense black short hairs both above and below, with some longer outstanding hairs on upper side basally. Although some authors have grouped it with some other genera based on chaetotaxy of the head, it was considered closer to Parapachycerina Stuckenberg. Other authors, on the other hand, noted very important differences in the male terminalia, shape of the syntergosternite 7+8 and phallic complex, stressing a view that there are many convergent similarities in unrelated Old and New World lauxaniid genera. This shows that there is some conflicting evidence about the position of Neopachycerina within the Lauxaniidae, but a precise affiliation of Neopachycerina to any genus or group of genera still depends on a global cladistic analysis of the Lauxaniidae genera. In the present paper, Neopachycerina nigra sp. nov., from Argentina, is described and N. aristata Malloch, 1933 is redescribed, with illustrations of both species.
Abstract in English:Abstract Based on material recently collected in Peru (Loreto department) the female of Poeciloxestia plagiata (Waterhouse, 1880), and the male of Iuati spinithorax Martins & Galileo, 2010 are described and figured for the first time.

Abstract in English:Abstract Pupae of chafer beetle (Melolonthidae) Cnemida retusa (Fabricius, 1801) (Rutelinae, Rutelini) were collected in October and November of 2017 in a decaying log at Reserva Florestal Adolpho Ducke, Manaus, Amazonas, Brazil, and are described and illustrated. The pupa description is the first to the genus and a key to known pupae of Rutelini is added.
Abstract in English:Abstract Philornis larvae and pupae were collected in nestlings of Neothraupis fasciata (Lichtenstein), the White-banded Tanager (Passeriformes, Thraupidae), in three breeding seasons, between October and November 2003-2005 in a reserve in central Brazil. Here, we present biological data, diagnosis to the recognition of the species and a key to the segregation of species occurring in the Cerrado. The larvae were intradermic in the nestlings and the pupae were collected in the nests after the birds have abandoned them. The immatures collected were taken to the laboratory and reared under laboratory conditions, until emergence. The species identified as Philornis torquans (Nielsen), is here firstly recorded from the Brazilian Cerrado, and firstly recorded its association with N. fasciata. With this record, the number of Philornis species occurring in the Cerrado rises to three.
