Abstract One new species is described in Ectenessini: Ectenessa monnei sp. nov. Five new species are described in Rhinotragini: Eclipta monnei sp. nov.; Ecliptoides pepemujicai sp. nov.; Ischasia carlosgardeli sp. nov.; Odontocera monnei sp. nov.; and Odontocera susanae sp. nov. New country records are reported for Eclipta taraleaphila (Tavakilian & Peñaherrera-Leiva, 2003) and Ecliptophanes chacunfrancozi (Tavakilian & Peñaherrera-Leiva, 2003). New Brazilian state records are reported for Ecliptoides pilosipes (Peñaherrera-Leiva & Tavakilian, 2004), Phygopoda fulvitarsis Gounelle, 1911, and Pseudophygopoda subvestita (White, 1855). Panamapoda Clarke, 2014 is synonymized with Pseudophygopoda Tavakilian & Peñaherrera-Leiva, 2007. Therefore, Pseudophygopoda panamensis (Giesbert, 1996) is a new combination. The differences between Pseudophygopoda Tavakilian & Peñaherrera, 2007, Paraphygopoda Clarke, 2014, and Paramelitta Clarke, 2014 are reported. The correct sex of the holotypes of Bomarion anormale Thomson, 1867 and Ectenessa ornatipennis Tippmann, 1960 is reported in the remarks of Ectenessa monnei sp. nov.

Abstract Except for Eligmoderma politum Nonfried, 1895, all known species of Eligmoderma are illustrated, some of them for the first time, with notes on them. Eligmoderma spinicolle Aurivillius, 1924 is revalidated. Although it was not possible to locate the holotype of Eligmoderma ziczac Nonfried, 1895, and we do not know whether the specimen still exists, we identified two specimens that we believe belong to this species, based on the details provided in the original description. Eligmoderma convexicolle Aurivillius, 1924 is synonymized with E. trifasciatum Aurivillius, 1924. Eligmoderma monnei sp. nov. is described from Venezuela.

Abstract We present the first comprehensive survey of Cerambycidae (Coleoptera) from the Parque Estadual de Porto Ferreira, São Paulo, Brazil. A total of 349 specimens representing 101 species in five subfamilies were collected. All the species are illustrated, as well as others used for morphological comparison. We provide taxonomic, morphological and/or distributional information on all the species. Two species are described as new: Eclipta migueli sp. nov. and Olivensa ferreirensis sp. nov. Seven species are recorded for the first time from São Paulo State: Cosmocerus strigosus Guérin-Méneville, 1844, Alcidion ludicrum (Germar, 1823), Lophopoeum kawense Roguet, 2022, Polymitoleiopus nutrix (Nascimento, Santos-Silva & Flechtmann, 2021), Macronemus analis (Pascoe, 1866), Macronemus filicornis (Thomson, 1861), and Adesmiella cordipicta Lane, 1959. For the first time, we report and illustrate the male of Aegomorphus geminus (Galileo & Martins, 2012) and the females of Hesycha jataiensis Galileo, Martins & Santos-Silva, 2015, Polymitoleiopus nutrix, and Adesmiella cordipicta, the latter described and designated as neotype. Hyperplatys canus (Bates, 1863) is proposed as a new synonym of H. argentinus Berg, 1889. The genus Criopsis Thomsom, 1861 is transferred from Acanthoderini to Acanthocinini. Additional nomenclatural notes include corrections to the species-group name of Probatiomimus signifer (Thomson, 1865) and remarks on Pentheochaetes mysticus var. mediomaculatus Gilmour, 1957.

Abstract Cendiuna Galileo & Martins, 1991 is a genus of the tribe Hemilophini known from the Brazilian Atlantic Forest, and currently comprising five species. The genus is mainly diagnosed by having the pronotum depressed at the mid-posterior region, and elytra slightly widened toward apical region, with light dense pubescence laterally. Besides that, its species present patterns of firefly-like coloration. Herein, we describe Cendiuna migueli sp. nov. from the state of Paraná (Brazil). Additionally, we provide a new record of Cendiuna puranga Galileo & Martins, 1991 from Paraná and point out new variations in the species.

Abstract Notes and figures are provided for all known species of Rhathymoscelis Thomson, 1861 and for the related monospecific genera Mendesina Lane, 1974 and Cauarana Lane, 1974. These are proposed here as a well-defined generic group, the Rhathymoscelis-group, and are briefly described. All three genera were formerly usually classified in the subfamily Necydalinae Latreille, 1825 or tribe Necydalini of the subfamily Lepturinae Latreille, 1802, but the group is here confirmed as belonging to the subfamily Cerambycinae Latreille, 1802 based on characters of larval exuviae of Rhathymoscelis monnei Vlasak & Santos-Silva sp. nov., described from Peru. The publication date of R. melzeri Costa Lima is corrected from 1922 to 1923. A new Mexican state record is provided for R. rothschildi Lane, 1965. Rhathymoscelis haldemanii Thomson, 1861 is excluded from the Guatemalan fauna.

Abstract We provide a checklist of Cerambycidae species deposited in the Coleção Entomológica UFFS-RE, sampled with Malaise traps in forest remnants of southwestern region of the Brazilian state of Paraná. The subfamilies Cerambycinae, Lamiinae, Lepturinae, and Prioninae were recorded totaling 168 morphotypes, with 128 species identified. This study provides 14 new records of Cerambycidae species for the state of Paraná and one new record for Brazil (Callia paraguaya Galileo & Martins, 2002). This checklist is the first focused on cerambycids from the southwestern Paraná, contributing to fill in the knowledge of species distribution in the state and in Brazil, helping to reduce the Wallacean shortfall in cerambycid biodiversity.

Abstract The paper summarizes known information on Cassidinae fauna of Pernambuco. It is based on excerption of literature data, study of museum material, and implements also records from iNaturalist to create as complete picture of the cassidine fauna of Pernambuco as possible at the moment. Yet the region has high potential for future research as the state of Pernambuco hosts a significant portion of the Atlantic Forest’s northeast sector and thus occurrence of further species is to be expected. As a result, a total of 120 species are reported from the state, 67 of them representing the first distributional records. Furthermore, following taxonomic and nomenclatural acts are proposed based on the study of relevant type material: Heptachispa lineaticollis (Pic, 1928) comb. nov. is transferred from the genus Heptispa Weise, 1906 and Uroplata rectangula Uhmann, 1953 stat. nov. is raised to a species rank, previously it was considered a form of Uroplata girardi Pic, 1934. To facilitate future research on Cassidine fauna of Pernambuco a key to Cassidine tribes occurring there is proposed.

Abstract A taxonomic review of the monotypic genus Trochalonota Westwood, 1833, endemic to the Atlantic Forest in southeastern Brazil (Espírito Santo and Rio de Janeiro), is presented. Trochalonota badia (Germar, 1823) is redescribed, and its aedeagus is described and illustrated for the first time. The study further provides a diagnosis, a detailed nomenclatural history, and photographs of both syntypes and non-type material. A lectotype and paralectotypes are designated, and a distribution map is included. In addition, the genus is compared with Pixis Chevrolat, 1843, which has been considered in the literature as the most morphologically similar genus occurring in Brazil. A nomenclatural history of Pixis and remarks on its diversity and type species are also provided.

Abstract in English:

Abstract The study of the original description and the holotype - and only known specimen - in the Natural History Museum, London, allows us to transfer the Brazilian Amazon species Choeridium tridenticeps Arrow, 1913, currently treated in Ateuchus Weber, 1801 (= Choeridium Le Peletier de Saint-Fargeau & Audinet-Serville, 1828), to the genus Canthidium Erichson, 1847. Features such as a trituberculate head, protibiae serrated along the outer edge, and a row of deep punctures covering the posterior edge of the pronotum are alien to Ateuchus, but commonly found in Canthidium. At the same time, the specimen matches all known diagnostic features of Canthidium, with the posterior pronotal punctation placing it in the subgenus Neocanthidium Martínez et al., 1964. The new combination Canthidium (Neocanthidium) tridenticeps (Arrow, 1913) is thus established. Canthidium now includes 176 species. The C. tridenticeps holotype was collected during the Amazon leg of the 1911 Stanford Expedition to Brazil, along the Madeira-Mamoré Railroad, then under construction. We provide coordinates for each of the construction camps visited by the collectors W.M. Mann and F. Baker, including Camp 28 (09°38′57″S, 64°58′05″W), in modern Mutum-Paraná (Porto Velho, Rondônia), the type locality of C. tridenticeps. This is a preliminary contribution from our ongoing Ateuchus and Canthidium revisionary projects.

Abstract Monneocratesgen. nov. is proposed herein to accommodate the enigmatic species Stenocrates nasutus Dechambre, 1979 (Coleoptera: Scarabaeidae: Dynastinae), resulting in a new combination. Additionally, Monneocrates parabolicus sp. nov. is also described. The new genus is placed within the tribe Phileurini based on the characters of the mentum: laterally expanded and nearly entirely covering the first labial palpomere in ventral view. Illustrations, diagnoses, and a geographical distribution map are provided for Monneocrates species, including a first record of S. nasutus from Brazil. Finally, a discussion on the diagnostic characters used to define the new genus and the differences of its species from Stenocrates Burmeister, 1847, as well as the justification for placing the new genus within Phileurini, are presented.

Abstract Curticornis Gordon, 1971 comprises five species of neotropical lady beetles. This genus was proposed by Gordon to include species of the Cryptognathini with a laterally expanded clypeus that divides the eyes. All its species are black with some reddish area or vice versa, and smaller than 2.3 mm. Curticornis is the only genus among the similar genera of Pentiliini and Cryptognathini without any species occurring in Brazil. The present study describes the first Curticornis species from Brazil, Curticornis monnei Duarte-de-Mélo & Churata sp. nov., and updates the identification key proposed by Gordon. The key now includes six Curticornis species.

Abstract Six new species are described: Chnoodes migueli Churata & Duarte-de-Mélo sp. nov. (Brazil), Chnoodes felis Churata & Almeida sp. nov. (Peru), Exoplectra luciae Churata & Basílio sp. nov. (Peru), Gordonita guillermoi Churata & Almeida sp. nov. (Bolivia), Gordonita norae Churata & Almeida sp. nov. (Bolivia), and Gordonita tijeoi Churata & Almeida sp. nov. (Peru). In addition, the following taxonomic changes in Chnoodes Chevrolat and Exoplectra Chevrolat are proposed based on the study of type material: Novius bipunctatus (Gorham, 1895) comb. nov., Platynaspis bistripustulata (Ritsema, 1876) comb. nov., and Zenoria irregularis (Crotch, 1874) comb. nov.

Abstract Nyctocrepis is a lineage of moderate-sized (1-2 cm) fireflies endemic to the Atlantic Rainforest, in Brazil. All three Nyctocrepis species are brightly-colored, presumably diurnal, and feature narrow distribution ranges. Herein we describe and illustrate Nyctocrepis monnei sp. nov., recorded from an urban natural park, the Floresta da Tijuca, in Rio de Janeiro State, Brazil. This new species is unique among its congenerics by the following combination of features: smaller length (~0.8-1.1 cm); frontoclypeo-labral suture membranous; elytron subparallel-sided, pronotum and pronotal disc totally black - except for pair of anterolateral vitreous spots -, and elytron with basal half orangish-yellow and apical half dark-brown; antennal lamellae about 2-3.3× longer than core antennomere; phallus with dorsal plate ridges feebly developed, paramere inner margin slightly concave at apical half, basally smooth, and with an apical concavity at the outer margin. Our study highlights the underestimation of firefly diversity even within large metropolises, and the value of urban parks in protecting endemic species and biodiversity at large in the Atlantic Rainforest.

Abstract Arnaudius Grossi & Bartolozzi, 2011 is a stag beetle genus endemic to Peru, currently comprising three described species. In this study, we describe a fourth species for the genus, Arnaudius monnei Soares & Grossi sp. nov., based on two specimens collected in Machu Picchu, Peru. This new species shares all the diagnostic features of the genus, particularly those related to the male genitalia, the most unambiguous. The description of this new species calls attention to the unknown diversity of Lucanidae in the Tropical Andes, a region with high endemism, but which still remains largely undersampled. The new species is described, illustrated, and compared with the other species of the genus. Additionally, we provide an updated identification key for the males of the species of Arnaudius and a known distribution map.

Abstract The rove beetle subtribe Gyrophaenina comprises obligatory inhabitants of mushroom fruiting bodies, with 1,126 described species. However, their diversity and life histories in Neotropics remain poorly understood. Here, we report the first record of Phanerota vecta (Pace, 1990) from Brazil, significantly expanding its known distribution in South America. A detailed redescription of the adult is provided, elucidating unique diagnostic features of the aedeagus and morphological details in tergite VIII that were not documented in the original description. We also present the first complete larval description for the species, contributing to the limited knowledge of Gyrophaenina immature stages. Furthermore, the association of P. vecta with the poroid fungus Favolus sp. is reported, broadening the known host range for the genus. These findings provide crucial data for taxonomy, ecology and evolutionary understanding of specialized mycophagous Aleocharinae.

Abstract The genus Dilacera Zilberman & Pires-Silva (Termitonannini: Termitonannina) was recently established to include a single species found in the Amazonian Forest in Manaus, associated with termites of the genus Uncitermes Rocha & Cancello. Here, we report a further and second new species from Pará, D. monnei sp. nov. The new species is described, illustrated, and compared with the previously known species; it is supposed to be termitophilous, but the host is unknown. The new species can easily be distinguished from D. exokosmos by the color of head, pronotum and elytra being overall dark brown; pronotum relatively more elongate; row of four macrosetae on the dorsal margins of head delimitating the eye; rows of bristles on sternites overall uniformly black across the abdomen; spermatheca with capsule shaped as a flattened “dome”.

Abstract Hypotelus monnei Paiva & Caron sp. nov., is a new species of minute rove beetles (Coleoptera: Staphylinidae, Piestinae) described from Brazil. We have also added the new species to the dichotomous key of Hypotelus Erichson, 1839 and verified the monophyly of the genus, now including the new species. Hypotelus monnei sp. nov. is similar to H. corniculatus Bortoluzzi & Caron, 2017, but differs by having the head distinctly darker than the pronotum, frontal processes one-fourth to one-third the length of the antennal scape, antenna shorter than that of H. corniculatus with antennomere IV subquadrate, and sternite VIII with sinuous posterior margin. The new species shares morphological characters with four species that comprise a clade previously referred to as Clade C. Until now, the species of this clade were distributed from Costa Rica to Brazil and concentrated in tropical rainforests. The new species represents the southernmost and easternmost distribution of Clade C, and is the first species of this clade to occur in Brazil. With this addition, Brazil now records three species of Hypotelus.

Abstract Nilio Latreille (Tenebrionidae: Nilioninae) previously comprised 42 species distributed across three subgenera: N. (Nilio) Latreille (with 34 species), N. (Micronilio) Pic and N. (Linio) Bouchard & Bousquet (each containing four species). Based on examination of type material of 30 Nilio (Nilio) species and other 462 specimens from national and international collections, this study describes five new species: N. (N.) domingosi Macari & Almeida sp. nov., N. (N.) monnei Macari & Almeida sp. nov., N. (N.) mukambu Macari & Almeida sp. nov., N. (N.) pachamama Macari & Almeida sp. nov. and N. (N.) panicaseus Macari & Almeida sp. nov. This study brings the total number of Nilio extant species to 47, with 39 now assigned to N. (Nilio).

Abstract The genus Macrocis Reitter, 1878, is reinstated to accommodate the species previously placed in the Cis taurus species group, as follows: Macrocis bahiensis (Pic, 1916), new combination; Macrocis cornelli (Lawrence, 1971), new combination; Macrocis diabolicus Reitter, 1878, reinstated status; Macrocis grandicornis Pic, 1917, reinstated status; Macrocis longipilis (Pic, 1930), new combination; Macrocis pubescens (Friedenreich, 1881), new combination; Macrocis rufescens Pic, 1922, reinstated status; Macrocis setifer Gorham, 1883, reinstated status; Macrocis taurus Reitter, 1878, reinstated status; Macrocis testaceimembris Pic, 1916, reinstated status; and Macrocis testaceus Pic, 1916, with the unnecessary replacement name Cis kawanabei Lopes-Andrade, 2002, proposed as its junior synonym. The genus Trichapus Friedenreich, 1881, previously synonymized with Cis Latreille, 1797 and treated as part of the Cis taurus species group, is here synonymized with Macrocis. In addition, we describe Macrocis monnei Lopes-Andrade, Souza-Gonçalves & Sandoval-Gómez sp. nov., the first species of Macrocis recorded from the state of Tocantins, in the North Region of Brazil.

Abstract The Entomological Collection of the Museu Nacional/UFRJ, Brazil (MNRJ), served as the primary repository for Brazilian Orthoptera (Insecta), housing the country’s largest assemblage of this order and one of the most prominent in South America. This paper presents a revised and illustrated catalog of the name-bearing specimens (types) of grasshoppers (Orthoptera: Romaleidae) from the MNRJ. These types and their respective primary biodiversity data were digitized during on-site inspections by the Brazilian national biodiversity platform, Sistema de Informação sobre a Biodiversidade Brasileira (SiBBr). A historical overview of the Orthoptera Collection from the MNRJ is provided. A total of 61 species nomina were recorded, comprising 59 holotypes and 2 neotypes, belonging to 24 genera, 4 subtribes, 9 tribes, and 2 subfamilies. The complete type series of the species nomina related to the types were also surveyed, detailing their catalog numbers, type status, figures, type localities, main references, primary data, total number of the type series along with the collections where they were originally destined, and essential links. All types were originally destined for MNRJ, except the holotype of Pseudonautia nigrithorax Descamps, 1978 (FHCE, Uruguay). The neotype of Acridium olfersii Burmeister, 1838 from the MNRJ may become invalid in view of the apparent rediscovery of syntypes in the MLUH, Germany. We also discuss the use of terms not recognized by the International Code of Zoological Nomenclature (ICZN) - ‘neoholotype’ and ‘neoparatype’ - while clarifying the status of “true” versus “fake” types. All types digitized by the SiBBr were lost in the Palácio de São Cristóvão fire on September 2, 2018. However, no name-bearing specimens belonging to 47 species nomina, destined for external collections, likely remain preserved. Conceived for a special volume honoring Prof. Dr. Miguel A. Monné, this paper updates his previous type catalogs by resolving numerical/typographical discrepancies of the MNRJ Orthoptera Collection, as well as discussing concerning post-disaster nomenclatural trends and best practices for types. Equally important, it publishes for the first time the rescued primary biodiversity data alongside unpre cedented high-resolution images of these types. This integration establishes a permanent, living dataset that provides a robust taxonomic foundation for Neotropical Romaleidae. Ultimately, this work demonstrates that digitizing specimens and their primary biodiversity data is a critical strategy to preserve information for future research and to safeguard the heritage of Natural History Collections against catastrophic events.

Abstract The genus Marilia, with 83 extant species distributed across the Oriental, Australasian, and Neotropical regions, is the most diverse within the caddisfly family Odontoceridae. In Brazil, 28 species are currently known, 15 of which occur in the Atlantic Forest - one of the world’s 36 major biodiversity hotspots. In this study, we describe and illustrate two new species of Marilia from Atlantic Forest in the state of Rio de Janeiro, southeastern Brazil: Marilia monnei sp. nov. and Marilia catiae sp. nov. Additionally, we expand the known geographical distribution of Marilia maxakali Bonfá-Neto, Salles & Vilarino, 2023 to include the states of Rio de Janeiro and Santa Catarina. This study significantly contributes to bridging the knowledge gaps on caddisflies in the Atlantic Forest, resulting from both Wallacean and Linnean shortfalls.
