Two new species of Protohyale (Amphipoda: Senticaudata: Hyalidae) from remote oceanic islands of Trindade and Saint Peter and Saint Paul, Brazil
type: item
description: Two new species of the hyalid amphipod genus Protohyale Bousfield & Hendrycks, 2002 are described from remote oceanic islands off Brazil. Protohyale trinitensis sp. nov., from Trindade Island, was previously misidentified as P. macrodactyla (Stebbing, 1899). The new species is distinguished from congeners by the adult male gnathopod 1 with the palmar corner defined by a blunt spine accompanied by two robust setae, and by the male gnathopod 2 with a nearly straight palm lacking processes and lined with long plumose setae. Protohyale sanctipauli sp. nov., from the Saint Peter and Saint Paul Archipelago, can be recognized by the adult male gnathopod 1 with the palmar corner defined by a single robust seta and by the male gnathopod 2 with a concave palm occupying almost the entire posterior margin and defined by two robust setae. With the description of these species, the genus Protohyale now includes 49 recognized species worldwide. The occurrence of P. trinitensis sp. nov. also demonstrates that previous Brazilian records attributed to P. macrodactyla likely represent misidentifications, indicating the need for a taxonomic reassessment of that species in the region.

A new species of Rhinotocinclus Reis & Lehmann 2022 (Siluriformes, Loricariidae) from Rio Oiapoque basin, Brazil, with comments on the R. collinsae group
type: item
description: A new species of Rhinotocinclus is described from the Rio Oiapoque basin in the Amazon basin. The new species belongs to its genus by the presence of a canal cheek-plate on the ventral surface of the cranium that is elongated posteriorly and contacts the anterior margin of the cleithrum. The new species is assigned to the R. collinsae group, including R. collinsae, R. halbothi, and R. hardmanni. The R. collinsae group is diagnosable from other congeners by: 1) the presence of conspicuous dark dots smaller than the pupil diameter, 2) darkened sensory pores present on head, 3) snout coloration uniform, 4) odontodes on ventral surface of pelvic-fin unbranched ray aligned with main ray axis, and 5) accessory teeth on both premaxilla and dentary. The new species differs from other species of the R. collinsae group by having the second and third lateral stripes fused into one broad dark stripe surpassing the lateral line between the anal-fin and caudal-fin bases. The new species occurs in the rio Oiapoque basin, the geographically closest basin to the currently known distribution of the group.

Addressing nomenclatural issues in South American marine bivalves
type: item
description: This paper critically examines several taxonomic issues specific to the South American bivalve fauna, with a particular focus on the Atlantic coast. Some of these issues are introduced or endorsed by Huber’s two compendia on bivalves (2010, 2015), which led to significant taxonomic and nomenclatural changes across the global Bivalvia. Here four nomina oblita/nomina protecta cases are analyzed in this study. One of them is resolved: Phyllodina tenuisculpta (Sowerby II, 1868) is treated as a nomen oblitum, while Phyllodina persica (Dall & Simpson, 1901) is recognized as a nomen protectum. For the remaining three cases, this paper fulfills the requirements of Article 23.9.2 in asserting that status; however, a definitive resolution depends on submissions to the Commission to address pending issues to attend Articles 23.9.3 and 23.9.6. All arguments are presented in detail. The taxa are: Temnoconcha galathaea (Lamarck, 1818) should be considered a nomen oblitum, with Temnoconcha brasiliana (Dall, 1921) recognized as valid and nomen protectum. Similarly, Chionopsis crenata (Gmelin, 1791) should be also identified as a nomen oblitum, with Chionopsis pubera (Bruguière, 1791) established as valid and nomen protectum, including a rectification of authority. Spondylus tenuis Schreibers, 1793 and S. ambiguus Chenu, 1844 should be classified as both a nomen oblitum and, the former, a possible n. dubium, while Spondylus ictericus Reeve, 1856 should be accepted as valid and nomen protectum. Four synonymies are also analyzed. The synonymy of Anomalocardia flexuosa (Linnaeus, 1767) and A. brasiliana (Gmelin, 1791) is provisionally accepted, considering that they may represent distinct entities, as is the case with Tivela dentaria (Lamarck, 1818) and T. isabelleana (d’Orbigny, 1846). The synonymy between Sphenia fragilis (H. & A. Adams, 1854) and Sphenia antillensis Dall & Simpson, 1901 is rejected, with the latter updated to S. iheringiana (Pilsbry, 1897). Additionally, the synonym…

Cecidomyiidae (Diptera): richness and distribution in the Amazonian forest
type: item
description: The present study aimed to survey the richness and distribution of gall midge species (Cecidomyiidae) in the Amazon forest. Additionally, we compilated data on the characterization of insect galls and host plant species identification, and developed a taxonomic key of gall midge genera registered in the Amazon forest. For this, data were obtained from the literature, but also from papers containing the original description of each gall midge species. A total of 31 gall midge species have been recorded in the Amazonian forest, with the majority reported in the Brazilian Amazon (29) and two species found in the Peruvian Amazon. The genera Lopesia was the best represented among gall midges. Calophyllaceae were the plant family with the greatest number of gall midge species. Leaves were the most attacked plant organ (74%). Most morphotypes are globoid (75%), green (42%), glabrous (58%), and one-chambered (55%). The state of Amazonas (Brazil) and the department of Loreto (Peru) recorded the highest number of gall-inducing species. Furthermore, 17 gall midges species were described from the Brazilian Amazon, while only two species were described from the Peruvian Amazon. The remaining species (12) were described from other biomes and latter recorded in the Amazon forest. In the 20th and 21st centuries, 13 and six gall midges species were described, respectively, being Rübsaamen and Maia the authors who described the highest number of species. After 1921, there was an 85 years interval without new taxonomic contributions until 2006, when two new species were described from the Amazon forest. The taxonomic key for gall midge genera stands out as one of the few available for distinguishing genera in the Neotropical region, facilitating the work of taxonomists. It is also the first taxonomic key specifically designed for this phytogeographic domain. In order to fill these gaps in the taxonomic information on gall-inducing insect species in the Amazon forest, more efforts are …

Establishment of Leontocarididae fam. nov. for Leontocaris Stebbing, 1905 (Decapoda: Caridea)
type: item
description: A new caridean shrimp family, Leontocarididae fam. nov., is established to accommodate the deep-water genus Leontocaris Stebbing, 1905, with nine species. The new family can be separated from all other caridean families by the extremely unequal and asymmetrical second pereiopods, with carpus subdivided into four subarticles, the first by far longest, and three much shorter, enlarged, distal subarticles; the chela of the major second pereiopod markedly enlarged, with twisted, lamina-like dactylus and tympanum on mesial face of the palm; the merus of the major second pereiopod with a flange on proximal mesial surface, forming together with the tympanum a chela locking mechanism; the antennal scaphocerite with lateral margin strongly dentate in distal half or third; the uropodal exopod with lateral margin strongly dentate in distal half; and the diagnostic late larval stages (problemacaris larva). Leontocaris is subdivided into three informal species groups based on the combination of several morphological characters.

The birds of Angatuba Ecological Station, southwestern São Paulo state, Brazil
type: item
description: The Angatuba Ecological Station (AES), located in an ecotonal region between the Atlantic Forest and Cerrado domains in southwestern São Paulo state, represents one of the few integral protected areas safeguarding interior Semideciduous forest remnants. We conducted rapid avifaunal inventories in December 2024 and in August 2025, integrating systematic field surveys with secondary data from published literature and ornithological platforms to update the knowledge of the local bird assemblage approximately 18 years after the last comprehensive survey. Primary data yielded 158 species and when combined with historical and secondary records (1984-2025), a total of 260 species were documented for AES, of which 215 were supported by documentation. A temporal accumulation curve highlights the continued addition of species over four decades, reflecting both genuine faunal updates and increased observer effort through citizen science platforms. Our results confirm the high conservation value of AES within the upper Paranapanema basin and underscore the importance of integrating historical, institutional, and community-based data to assess species persistence, regional connectivity, and conservation priorities in ecotonal neotropical landscapes.

title: Specimens lost, biodiversity data preserved: Part I. A revised and illustrated catalog of the name-bearing types of grasshoppers (Orthoptera: Romaleidae) from the Entomological Collection of the Museu Nacional/UFRJ, Brazil
description: 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/typographic…

Choeridium tridenticeps Arrow, 1913: a Canthidium Erichson, 1847, not an Ateuchus Weber, 1801 (Coleoptera, Scarabaeidae, Scarabaeinae)
type: item
description: 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.

First description of nest and egg of the Slate‑colored Hawk Buteogallus schistaceus (Sundevall, 1850) (Aves, Accipitriformes, Accipitridae)
type: item
description: The Slate-colored Hawk, Buteogallus schistaceus (Accipitridae), is a poorly known Amazonian raptor, particularly with regard to its breeding biology. Here we report the first documented nesting record of the species in Brazil, based on observations conducted at the Samuel Hydroelectric Reservoir, municipality of Itapuã do Oeste, Rondônia state. The nest was in a babassu palm (Attalea speciosa), 16 m above ground, and contained a single egg. Nest placement, architecture, egg measurements, adult behavior, and foraging observations are described. This record fills an important gap in the knowledge of the species’ reproductive biology and contributes to the documentation of Neotropical Accipitridae.

The presence of Diphaglossa gayi Spinola in Argentina (Hymenoptera: Colletidae)
type: item
description: We report the presence of Diphaglossa gayi Spinola, a solitary bee species of the family Colletidae, in Argentina. Until now, this species was considered endemic to Chile, where it is a common element of the Valdivian temperate rainforest fauna. The new records are based on both historical museum specimens and validated photographic observations from the citizen science platform iNaturalist, expanding the known distribution of the species into the Andean forests of Neuquén, Río Negro, and Chubut provinces. Data on distribution and floral associations are presented and discussed.

Phytoseiidae (Acari: Mesostigmata) on native Cerrado plants in a fragment in Eastern Mato Grosso do Sul, Brazil
type: item
description: Phytoseiidae mites are key natural enemies in agricultural and natural ecosystems. However, their diversity in some areas of the Cerrado biome, particularly in the state of Mato Grosso do Sul (MS), Brazil, remains poorly documented. This study aimed to survey the Phytoseiidae species associated with native plants in a Cerrado fragment in the municipality of Aparecida do Taboado, MS. Sampling was conducted quarterly over one year (2023-2024) on ten selected native plant species. A total of 268 adult mites were collected, belonging to 12 species in two subfamilies (Amblyseiinae and Phytoseiinae). The most abundant species were Euseius citrifolius Denmark & Muma (106 specimens), Phytoseius nahuatlensis De Leon (82), and Iphiseiodes zuluagai Denmark & Muma (36). Xylopia aromatica (Lam.) Mart. (Annonaceae) and Mabea fistulifera Mart. (Euphorbiaceae) were the plant species harboring the highest mite abundance. This study provides the first records of Amblydromalus zannoui Sourassou, Sarmento & Moraes and Phytoseius kaapre Demite, Lofego & Feres for the state of Mato Grosso do Sul. Furthermore, the findings suggest that plant – mite associations are influenced by leaf traits and food resources: P. nahuatlensis was dominant on the trichome-rich leaves of X. aromatica, I. zuluagai utilized leaf domatia on Matayba guianensis Aubl., and the abundant E. citrifolius was linked to M. fistulifera, likely utilizing its pollen. These data help fill a faunistic gap and highlight the role of native Cerrado vegetation as a reservoir of functional biodiversity, maintaining stable populations of natural enemies.

Surveys of terrestrial gastropods in three nature reserves in southeast Brazil
type: item
description: Though only a small fraction of its original natural cover remains, the Atlantic Forest is considered a land snail diversity hotspot. While this biome has been widely explored by malacologists in the past, modern surveys of important conservation areas are lacking. Here we report the results of surveys conducted in two nature reserves and one national park in Espírito Santo state: Parque Nacional Caparaó (a fraction of which is located in Minas Gerais state), Reserva Biológica Córrego do Veado, and Reserva Biológica Sooretama. In total, 15 families of terrestrial gastropods were represented, with 35 species identified, plus another five additional morphospecies that could not be fully determined; 16 species-level taxa in Caparaó, 23 in Córrego do Veado, and 22 in Sooretama. The following are new records for Espírito Santo state (or Minas Gerais state in the case of Caparaó): Rectartemon piquetensis, Anthinus multicolor, Burringtonia labrosa, Rhinus velutinohispidus. Only two non-native species were found, Subulina octona in Sooretama and the marsh slug Deroceras laeve in Caparaó. Anecdotal natural history records are also provided, including depigmented individuals of Leiostracus perlucidus. The importance of local faunal surveys, particularly in preservation areas, cannot be overstated as we endeavour to understand our molluscan fauna.

Hidden among the spores: adult and larval morphology of Phanerota vecta (Pace, 1990) (Coleoptera: Staphylinidae), a mycophilous beetle newly record from Brazil
type: item
description: 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.

A new species of Haplocochlias (Gastropoda, Skeneidae) from the Abrolhos Archipelago, Brazil
type: item
description: A new species of Haplocochlias Carpenter, 1864 (Gastropoda: Skeneidae), Haplocochlias pitico sp. nov., is described from the Abrolhos Archipelago, off the coast of Bahia State, Brazil. The species is characterized by its minute, turbiniform shell (1.3-1.4 mm in diameter), markedly rounded whorls, very short spire, smooth protoconch, and body whorl bearing 17 smooth spiral cords separated by interspaces with sinuous prosocline axial striae. The aperture is prosocline and rounded, with a thick, smooth peristome and a narrow but deep umbilicus encircled by two prominent cords. Haplocochlias pitico sp. nov. differs from all its congeners by the distinctive undulations on the upper part of the last whorl, particularly near the aperture. Comparisons with morphologically similar Atlantic species are provided. The present discovery, based on material collected more than four decades ago, demonstrates both the persistence of significant taxonomic gaps in reef-associated gastropod faunas and the enduring scientific value of museum collections for refining biogeographic patterns in the Southwestern Atlantic.

Baseline fish inventory of the Trombetas River rapids, a drainage of Southeastern of the Guiana Shield, Brazil
type: item
description: The Trombetas River basin, a clearwater tributary of the left bank of the Amazon River, originates in the southern portion of the Guiana Shield and flows into the state of Pará, Brazil. Upstream of Cachoeira Porteira, the river flows through a rocky channel with steep gradients and sandy-rocky substrates, forming numerous rapids and waterfalls. Despite the recognized biological importance of Guiana Shield rivers, comprehensive fish surveys remain scarce. Here, we conducted a rapid assessment of the fish community inhabiting rapids, primarily using diving-based collection methods, to document species diversity and community structure in a poorly explored environment. We collected 302 specimens, representing 53 species, 43 genera, 14 families, and seven orders. Siluriformes was the most species-rich order, followed by Characiformes, Cichliformes and Gymnotiformes. At family level, Loricariidae showed the highest species richness, followed by Cichlidae, Anostomidae and Apteronotidae. We also report the first occurrence of Asterophysus batrachus (Siluriformes, Auchenipteridae) in the Trombetas River and range extensions of the strictly rheophilic genera Hypancistrus (Siluriformes, Loricariidae) and Teleocichla (Cichliformes, Cichlidae). The rapids remain preserved mainly due to their location within protected areas, such as the Trombetas State Forest and traditional community territories. However, the proposed Cachoeira Porteira Hydroelectric Dam poses a significant threat to these habitats and their associated fauna, as this stretch of the Trombetas River encompasses one of the last remaining natural rapid systems in the Amazon Basin.

Dead bodies still tell tales: An alternative noninvasive and nondestructive protocol to extract cuticular hydrocarbons from museum specimens
type: item
description: Natural history museums represent valuable spaces for science outreach and as repositories of biodiversity data. The collections maintained in these institutions are often used as data sources for studies across various disciplines, such as ecology, phylogenetics, and population genetics. Another field that can also benefit from these resources is chemical ecology. Using insects stored in museums offers an alternative avenue for addressing new questions about the dynamics of their cuticular hydrocarbons (CHCs) with respect to different factors such as their interspecific variability, temporal stability and in chemotaxonomy. CHCs play a dual role in insects, serving as mechanical protection against desiccation and pathogens and mediators of communication processes. However, conventional extraction procedures can compromise the specimens given their invasive nature (e.g., hexane immersion approach). Here (1) we propose an alternative, noninvasive and non-destructive method to study CHCs in pinned insects from museum collections and (2) we examine the efficacy of this alternative compared to a more conventional approach for determining CHC profiles. We used two model organisms to address our goals, the Apis mellifera Linnaeus, 1758 and the Tetragonisca angustula (Klug, 1807). We were able to detect CHCs in pinned specimens from both species though there was a qualitative reduction in pinned specimens when compared to fresh ones. The observed variability may reflect confounding differences associated with sampling locality. Our results suggest that this alternative protocol can be applied to assess the CHC composition of museum specimens without causing destruction and represent an effective method to be used in studies integrating taxonomy and chemical ecology.

Cassidinae (Coleoptera: Chrysomelidae) from Pernambuco, Brazil: new records, nomenclatural changes, and identification key of tribes
type: item
description: 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.
