She has been dedicating the last six decades to the study of adults and immatures of Coleoptera. Dr. Costa is the pioneer in collecting and rearing immature beetles in Brazil, being responsible for establishing the most extensive Latin American collection of reared immatures Coleoptera. We discuss central aspects of her personal history, as well as career landmarks and achievements. A compilation of taxa introduced to science by her, taxa named in her honor, and a full list of her scientific, educational and cultural production are provided in chronological order. More than a biographical account, this publication is an acknowledgment of Dr. Cleide Costa’s legacy to entomology. <![CDATA[A new <em>Brachypsectra</em> LeConte from Australia (Coleoptera: Brachypsectridae) with comparative notes on adults and larvae]]> Abstract A new species, Brachypsectra cleidecostae Lawrence, Monteith &amp; Reid sp. nov., is described from Australia on the basis of one reared adult female from inland Queensland and larvae from the type locality and two other widely separated semi-arid localities in South Australia and Western Australia. Two of the four larval collections were from under tree bark and one was from ground litter. The species is differentiated on both adult and larval characters. The broader mandible with retention of a retinacular tooth may indicate a sister relationship with species of the genus from other continents. <![CDATA[Description of larva and pupa of the weevil <em>Hybolabus amazonicus</em> Voss (Attelabidae: Attelabinae), a leaf roller on Brazil nut (<em>Bertholletia excelsa</em>)]]> Abstract The last instar larva and the pupa of Hybolabus amazonicusVoss, 1925 are described and illustrated, based upon adults and immatures collected in the Amazonian Region (Acre and Amazonas, Brazil). The larvae live and develop inside a leaf-roll made by the female weevil. Although the species has already been reported damaging leaves of the Brazil nut (Bertholletia excelsa Humb. &amp; Bonpl., Lecythidaceae) in the states of Acre and Amazonas, the preimaginal stages have not been formerly described. These are the first descriptions of larva and pupa of a species of the genus Hybolabus Jekel, 1860. <![CDATA[A new species of the genus <em>Canthon</em> Hoffmannsegg (Coleoptera, Scarabaeidae, Scarabaeinae, Deltochilini) from central Brazil]]> Abstract A new species of Canthon is described, illustrated and the morphological similarities with related species are discussed. The species Canthon cleidecostae was named after Dr. Cleide Costa a great beetles specialist. The subgeneric category of species is considered incertae sedis until the taxonomic revision of the genus Canthon is fully addressed. Also, we provide a key for genera, subgenera and isolated species-groups that can be confused with the genus Canthon. <![CDATA[Descriptions of larval and pupal morphologies of <em>Macrohyliota militaris</em> (Erichson) (Silvanidae: Brontinae: Brontini)]]> Abstract The mature larva and pupa of the Australian silvanid species, Macrohyliota militaris (Erichson) are described from laboratory reared material. This is the first description of immature stages of Silvanidae from Australia. The larva of M. militaris conforms to the general body shape and apparent morphological features of known Brontini and is very similar to the Asian M. sculptus Yoshida &amp; Hirowatari. Larval and pupal features of M. militaris are compared with other known larvae and pupae of Brontini described in the literature. <![CDATA[A new genus of Phengodidae (Coleoptera) from the Neotropical Region]]> Abstract Cleicosta, a new genus of Phengodidae containing two new species, C. equatoreana sp. nov., and C. monaguense sp. nov., are described. Additionally, a new combination for Cenophengus breviplumatusWittmer, 1976 is included. Cleicosta gen. nov., is the thirty-eighth genus assigned to the beetle family Phengodidae in the new world and is also the most morphologically similar to Cenophengus LeConte, 1881. Both genera exhibit clearly separated tentorial pits, vertical frons and simple tarsomeres. In Cleicosta gen. nov., however, the antennal rami are 1.5 times longer than the corresponding antennomere, the pronotum is subquadrate and the elytra are short, reaching the first or second abdominal segment. In addition, it presents an aedeagus with lateral lobes slender, parallel exteriorly, narrowed medially to toothless apex. <![CDATA[Review of the genus <em>Hovorestenia</em> Santos-Silva (Coleoptera: Disteniidae)]]> Abstract HovoresteniaSantos-Silva, 2007 is a disteniid genus differentiated from other Neotropical Disteniini by the metatarsomeres II and V subequal in length, in contrast with the metatarsomere V distinctly longer than II in the other genera. So far, the genus is known only from male specimens. The discovery of new Hovorestenia species, represented by both sexes, shows that such current diagnostic character is sexually dimorphic, with metatarsomere V distinctly longer than II in female. The genus Hovorestenia is therefore reviewed and redescribed and two new species are described: H. cleideae, from Colombia and Ecuador, and H. espilota, from Colombia. It allowed to describe the hitherto unknown females and to appoint out sexually dimorphic characters for the first time in the genus. The genus is now composed of four species distributed from the central region of Colombia to Ecuador. Photographs of Hovorestenia species are included and a key to differentiate them is provided. <![CDATA[Description of the larva and pupa of <em>Apion brevicorne</em> Gerstaecker, 1854 (Coleoptera: Brentidae: Apioninae) with biological information]]> Abstract Apion brevicorne Gerstaecker, 1854 (Coleoptera: Brentidae: Apioninae) is an ecologically and economically important weevil that feeds on seeds and tissues of trees in the genus Copaifera L. (Fabaceae). Although the genus Apion comprises 16 species restricted to the Paleartic region, the Neotropical species A. brevicorne is still considered as incertae sedis due to the absence of a systematic study about it. The first descriptions and illustrations of Apion brevicorne are provided here. Diagnostic characters of larva and pupa are included and compared with 13 species from other biogeographic regions. Details of immature Apioninae species associated with host plants from the Neotropical region are described for the first time. <![CDATA[First species of <em>Laselva</em> Furth from Brazil (Chrysomelidae: Galerucinae: Alticini)]]> Abstract Laselva cleidae sp. nov., the first species of LaselvaFurth, 2007 found in Brazil is described and illustrated. Species of Laselva are compared with those of DeciplatusLinzmeier &amp; Konstantinov, 2009 and AndersonalticaLinzmeier &amp; Konstantinov, 2012. This is the first species of Laselva recorded to South America. <![CDATA[A new genus of railroad-worm beetles from the Atlantic Rainforest from Brazil (Coleoptera: Phengodidae, Mastinocerinae)]]> Abstract Here we describe a new genus, Cleidella gen. nov., and two new species, C. picea sp. nov. and C. silveirai sp. nov., all from Rio de Janeiro State, Brazil. The new genus is characterized by the interantennal distance subequal to scape length, antenna with 11 antennomeres, IV to X with two long symmetrical branches; mandibles long, projected and not crossed, pointed forward obliquely from head; maxillary palpi 4-segmented, last segment digitiform; labial palpi 2-segmented; posterior tentorial pit consisting of a single small fossa; elytron surpassing from the fourth to fifth abdominal segment, 3.3-3.9× longer than wide; first tarsomere of protarsus with a ventral comb as long as the tarsomere length; wing with radial cell closed and transverse, vein r4 interrupted; aedeagus with paramere symmetrical, apex unevenly round, toothed inward, with short and scarce bristles. We provide a key to Mastinocerinae genera with 11 antennomeres, as well as illustrations for the diagnostic features for this new genus and a key to its species. <![CDATA[Description of the late- or last-instar larva of <em>Ischyomius</em> Chevrolat, with comments on the family placement of the genus (Coleoptera: Tenebrionoidea: Pythidae)]]> Abstract Study of recently collected larvae of two species of Ischyomius Chevrolat, 1871 from Napo and Pichincha, Ecuador, tentatively identified as I. denticollis Champion, 1916 and I. singularis Chevrolat, 1871 confirm the classification of the genus Ischyomius within the family Pythidae. Salient larval characters which solidify this placement are: 5 stemmata arranged into an anterior column of 3 and posterior column of 2, parabasal ridges along anterior margins of abdominal tergites, prominent urogomphi with inner urogomphal teeth and various dorsal tubercles, and transverse row of dentiform asperities along anterior margin of sternite 9. Important features of the larva are illustrated with photographs. A key to larvae of world genera of Pythidae is provided as well as natural history information on Ischyomius. <![CDATA[<em>Austrolimnius cleidecostae,</em> a new species of riffle beetle (Coleoptera: Elmidae) from Brazil with habitat notes and updated key of the Brazilian species of the genus]]> Abstract Austrolimnius cleidecostae sp. nov. is one of the smallest species of Elmidae from the Neotropical region. The new species is described and illustrated based on male and female specimens. This species represents the first record in Elmidae of mandibles with an articulated, sclerotized process on inner subapical edge. The specimens were collected from streams in the Atlantic rainforest of São Paulo and Santa Catarina, and habitat notes are given. An updated key for the AustrolimniusCarter &amp; Zeck, 1929 of Brazil is provided. Austrolimnis browniHinton, 1971 and A. musgraveiHinton, 1939 are recorded for the first time from Brazil. <![CDATA[Morphology of immature stages of <em>Paraegidium costalimai</em> (Coleoptera: Scarabaeidae: Orphninae) and remarks on egg-busters in Scarabaeidae first-instar larvae]]> Abstract Studies about the immature stages of Orphninae (Coleoptera: Scarabaeidae) species are scarce. The subfamily includes 214 species, but only 5 have the immature stages described: Chaetonyx robustus liguricus Mariani, 1946, Hybalus benoiti Tournier, 1864, H. rotroui Petrovitz, 1964 and Triodontus nitidulus (Guérin, 1844) from Old World; and Aegidium cribratum Bates, 1887 from the New World. The Neotropical genus ParaegidiumVulcano, Pereira &amp; Martinez, 1966 encompass five species, mainly recorded from Brazil. Herein, the immature stages of P. costalimaiVulcano, Pereira &amp; Martinez, 1966 are described and illustrated, along with remarks on the presence of egg-buster in Scarabaeidae first-instar larvae. A key to the third-instar larvae of known Orphninae and a comparative study of chaetotaxy are also provided. <![CDATA[A new species of Neapion (Neotropion) Alonso - Zarazaga from Paraguay (Brentidae: Apioninae)]]> Abstract A new species of the genus NeapionAlonso-Zarazaga, 1990 subgenus NeotropionAlonso-Zarazaga, 1990 (Brentidae: Apioninae) is described and illustrated. Neapion (Neotropion) cleidecostae sp. nov. (Type locality: Paraguay, Misiones) is the second Apioninae species from South America with dense, thin vestiture and raised areas on the elytra. In addition to these characters, vestiture color pattern and male genitalic characters such as penis shape, length of the tuning fork-shaped sclerite in the internal sac (the largest found in Apioninae), and shape of the tegminal plate are diagnostic of this new species. <![CDATA[A generic key to the known larval Elmidae (Insecta: Coleoptera) of French Guiana]]> Abstract An identification key is provided for 21 larval types of Elmidae (riffle beetles) known to occur in French Guiana. Not all elmid genera known to occur in French Guiana are known in the larval stage. Nor are all the known larval types assigned to known elmid genera. <![CDATA[A revision of <em>Peltariosilis</em> Wittmer (Coleoptera: Cantharidae), a surprisingly diverse Amazonian radiation]]> Abstract PeltariosilisWittmer, 1952 is a South American Silinae genus characterised by the highly modified male pronotum and scutellum with a remarkable lamellar projection. Six species were previously recognised. The study of numerous specimens from previously unsampled localities and the revision of previously studied material shows that Peltariosilis is far more diverse than previously recognised. 15 species are here recognised as valid, nine of which are described as new: P. brancuccii, P. brunneoapicalis, P. cleidecostae, P. diversicollis, P. flavicornis, P. gracilicornis, P. major, P. orientalis and P. parviscutellaris spp. nov. A comparative study and new morphological terminologies are introduced for pronotum, scutellum and male genitalia. All Peltariosilis species are described and illustrated, including the first illustration of a female pronotum, and an identification key is provided. A map is given, including records of all known Peltariosilis, showing a distribution confined to the Amazonian subregion (Suriname, French Guiana, N Brazil, E Peru and NE Bolivia). The identity of the type species P. scutulata (Wittmer, 1952), hitherto considered as broadly distributed and highly variable, is addressed through study of their type series and additional specimens from widespread localities. <![CDATA[<em>Laccodytes costae</em> sp. nov., and new records for the genus from Brazil (Coleoptera: Dytiscidae)]]> Abstract Laccodytes costae sp. nov., from Brazil, is described and illustrated; the new species is the third known member of the Laccodytes apalodes species-group. New records for Brazil: Laccodytes americanus Peschet, 1919, new for the country and Laccodytes rondoniaToledo, Spangler &amp; Balke, 2010, new for the state of Pará. A modified version of the key from Toledo, Spangler &amp; Balke (2010) is provided with new couplets to allow the identification of the new species as well as L. cobreinaeToledo, Megna &amp; Alarie, 2011. <![CDATA[To be or not to be a tibial comb: A discussion on the (past) use of tibial armature in tribal/subtribal organization in Cholevinae (Coleoptera: Leiodidae)]]> Abstract Detailed studies of microstructure have recently been shown to provide phylogenetic signals at several supraspecific levels within leiodid coleopterans, as well as in other insects. The tribe Ptomaphagini (Leiodidae: Cholevinae), with a Holarctic-Neotropical-Oriental distribution, has been characterized, among other things, by having a comb of equal-sized, flat spines around the apex of the tibiae of all legs, with a row of spines extending along the outer edge of the protibiae in the subtribes Baryodirina and Ptomaphaginina (but not in Ptomaphagina). A pattern similar to the one in Ptomaphaginina also occurs in the Neotropical cholevine tribe Eucatopini, and this has been used to indicate a phylogenetic relationship between the two tribes (but recent phylogenetic studies have not supported such a close relationship). We here review and revise the presence and structure of periapical (here called an ‘apical crown’) and marginal (here called an ‘external comb’) combs of spines on tibiae in Ptomaphagini, using other cholevines (with and without apical tibial combs) for comparison. We find a phylogenetic signal in an apical crown of tibial spines not interrupted at the outer spur, which seems to be an additional synapomorphy of Ptomaphagini, differing from the pattern in Eucatopini and remaining cholevines with an apical comb of spines, in which the comb is interrupted. We highlight differences not previously noticed between the apical protibial armature of Ptomaphaginina and Eucatopini. <![CDATA[Two new species of <em>Passalus</em> Fabricius (Coleoptera: Passalidae) from the western Brazilian Amazon with comments on the taxonomic limits of the subgenera]]> Abstract Passalus Fabricius, 1792 is the largest genus of Passalidae and presents great diversity in South America, mainly in the Amazon region. Currently this complex and heterogeneous genus is subdivided into three subgenera: P. (Pertinax) Kaup, 1869, P. (Mitrorhinus) Kaup, 1871, and P. (Passalus). Herein, two new species of Passalus from the western region of the Brazilian Amazon, a diverse but poorly studied area, are described and illustrated. The new species Passalus (Pertinax) deuterocerus sp. nov. and Passalus (Passalus) cleidecostae sp. nov. are compared with similar species occurring in nearby regions. Also, the diagnostic characters used to define the subgenera and sections of Passalus are summarized. <![CDATA[Two new genera of Desmiphorini (Coleoptera, Cerambycidae, Lamiinae) with description of a species with non-retractile parameres]]> Abstract In this study, two new genera of Desmiphorini (Lamiinae) are proposed: Cleidaria gen. nov., to include Cleidaria cleidae sp. nov. from the state of Chiapas in Mexico, and Obscenoides gen. nov. for Desmiphora (D.) comptaMartins &amp; Galileo, 2005. The shape of tarsal claws of Cleidaria cleidae sp. nov. (abruptly narrowed from basal half) is so far, not found in any current genera of the tribe. With respect to Obscenoides compta (Martins &amp; Galileo, 2005) comb. nov., the genitalia of males have an unusual shape with non-retractile parameres. The character combination related to this genital structure is unknown to us in other species in the family, and hypotheses about its function are suggested. <![CDATA[New species and morphological notes on the termitophilous genera <em>Fonsechellus</em> Silvestri and <em>Oecidiophilus</em> Silvestri from Brazil (Staphylinidae, Aleocharinae, Corotocini, Termitoceina)]]> Abstract Fonsechellus Silvestri and Oecidiophilus Silvestri consist of two Neotropical genera of termitophilous rove beetles, which have been poorly characterized due to the scarcity of material for studies. Herein, based on material collected in the seventies and housed in the Museu de Zoologia da Universidade de São Paulo, two new species associated with Atlantitermes guarinim Fontes and Diversitermes sp., are described and illustrated: Fonsechellus heterosetosus sp. nov. and Oecidiophilus cleidecostae sp. nov., respectively. The latter represents the first record of the genus to Brazil. Also, Fonsechellus fragilis and F. fontesi are redescribed, and a key for species identification is provided for the genus. The condition of the membranous wings of Fonsechellus is addressed and discussed, and the definition of both genera is expanded. <![CDATA[Contribution to the knowledge of <em>Podischnus</em> Burmeister, 1847 (Coleoptera: Melolonthidae: Dynastinae) with the description of two new species from Brazilian Amazon Forest]]> Abstract Two new Podischnus Burmeister, 1847 species are described here: Podischnus limeirai sp. nov. from Gurupi region, Maranhão state, Brazil, the easternmost distribution of the genus; and Podischnus cleidecostae sp. nov. from the Acre state, Western of Brazilian Amazon Forest. New diagnostic characters are illustrated and discussed for the genus. An illustrated identification key for all Podischnus species, and an up-to-date distribution map for the Brazilian species of Podischnus are provided. Moreover, we propose the inclusion of P. limeirai sp. nov. in the Red List of Threatened Species (IUCN) due to the fast loss of the Oriental Amazon Forest remnant fragment in that region. <![CDATA[Elaphidiini (Coleoptera, Cerambycidae) from the Caribbean region of Colombia: New species, taxonomic notes and new geographical records]]> Abstract Two new species of Elaphidiini from Colombia are described: Sphaerion costae sp. nov., and Mephritus costae sp. nov. The keys to species of Sphaerion Audinet-Serville, 1834 and Mephritus Pascoe, 1866 are translated and modified to include the new species. Chromatic variations of Mephritus apicatus (Linsley, 1935) are reported. Moreover, the geographical distribution is expanded for 12 species of Elaphidiini. <![CDATA[Morphology and life cycle of a new species of <em>Psilocladus</em> Blanchard, 1846 (Coleoptera, Lampyridae, Psilocladinae), the first known bromeliad-inhabiting firefly]]> Abstract Fireflies (Coleoptera: Lampyridae) are soft-bodied beetles usually associated with mesic and hydric habitats. As such, terrestrial firefly larvae are commonly found in marshy environments and stream banks, while aquatic larvae might dwell in ponds, streams, mangroves, and even brackish water. Larval biology is especially important in fireflies, as the majority of species are extremely semelparous - that is, adults rely on resources gathered during larval stages. Despite their crucial relevance in firefly biology, larvae of only near 1% firefly species have been studied, and the majority of species remain known only from adult stages. That is especially true in the Neotropical region, where they are most diverse. Here, we describe Psilocladus costae sp. nov. after the study of adults and immature stages, the latter reported for the first time for the monotypic subfamily Psilocladinae McDermott, 1964. Interestingly, adults were first obtained by rearing the larvae, the former usually fly fairly high (ca. 10 m) and are therefore seldom collected at ground level by conventional methods (e.g., active search, Malaise traps). The new species is found in the Brazilian Atlantic Rainforest, inhabiting canopy bromeliads, an unprecedented habit for fireflies.
