Item Expanding the range of the troglobitic millipede Pseudonannolene ambuatinga Iniesta & Ferreira, 2013: insights into its distribution and conservation status (Spirostreptida, Pseudonannolenidae)(2024-06-10) Iniesta, Luiz Felipe Moretti ; Oliveira, Marcus Paulo ; Brescovit, Antonio ; Bouzan, Rodrigo SalvadorPseudonannolene Silvestri, 1895 (Spirostreptida, Pseudonannolenidae) is one of the most common genera of millipedes in Brazilian caves. To date, only three troglobitic species are known in a list of 56 species described for the genus. In this study, we report new records of the cave-dwelling species Pseudonannolene ambuatinga Iniesta & Ferreira, 2013 in Minas Gerais state. These records extend its distribution by approximately 600 km2, making it the most widely distributed cave-dwelling millipede in the country. We also provide a new assessment of its conservation status based on the records and threats to its populations.Item Everything is similar, everything is different! Trichorhina Budde-Lund, 1908 (Oniscidea, Platyarthridae) from Brazilian caves, with descriptions of 11 new species(2023) Campos-Filho, Ivanklin Soares; López-Orozco, Carlos Mario; Carpio-Díaz, Yesenia M.; Borja-Arrieta, Ricardo Luis; Gallão, Jonas Eduardo; Taiti, Stefano; Sfenthourakis, Spyros; Bichuette, Maria ElinaThe present work describes 11 new species of the genus Trichorhina from Brazilian caves in the states of Bahia, Mato Grosso do Sul, Minas Gerais, Pará, and São Paulo. Moreover, the distribution of T. tomentosa has been expanded to include the states of Mato Grosso and Minas Gerais. Additionally, a distribution map and a key for all Brazilian species of Trichorhina, including epigean ones, are provided.Item Two new troglobitic species of Iansaoniscus from Brazilian caves (Crustacea, Isopoda, Pudeoniscidae)(2022-06-14) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Ferreira, Rodrigo LopesIansaoniscus species are troglobitic terrestrial isopods of the Pudeoniscidae family. In this work two new species are described from caves in the Bahia state, northeastern Brazil; I. leilae sp. nov. from Toca do Gonçalo cave, in the municipality of Campo Formoso; and I. paulae sp. nov. from Lapa do Bode cave in the municipality of Itaeté. Additionally, ecological notes and conservation status are provided for both new species.Item New troglobitic species of Pectenoniscus Andersson, 1960 (Isopoda: Oniscidea: Styloniscidae) from Bahia state, Brazil(2023-07-18) Cardoso, Giovanna Monticelli; Ferreira, Rodrigo LopesFive new species of Pectenoniscus are described from Bahia state: Pectenoniscus monsviridis n. sp. and Pectenoniscus revelatus n. sp. from Serra do Ramalho Karst area; Pectenoniscus archaeos n. sp. and Pectenoniscus sepultus n. sp. from Serra de Iuiú Karst area; and Pectenoniscus caesarius n. sp. from Campo Formoso Karst area. Additional notes are provided on their habitats and threats.Item A new species of Metaprosekia Leistikow, 2000 (Oniscidea, Philosciidae) from caves of the State of Mato Grosso, Brazil(2023) Campos-Filho, Ivanklin Soares; Chagas Jr, Amazonas; Sfenthourakis, Spyros; Bichuette, Maria ElinaThe present work aims to describe a new species of Metaprosekia from siliciclastic caves from Caverna Nova and Caverna Ponte de Pedra, Utiariti Formation, Municipality of Diamantino, State of Mato Grosso. Metaprosekia utiariti n. sp. easily differs from the congeneric species in the shape of male pleopods 1 and 2. Moreover, a map illustrating the lithology and hydrographic characteristics where the specimens were collected and conservation remarks are given.Item Cave-dwellers Diploexochus (Isopoda, Armadillidae): new species and new records of the genus from Brazil(2023-01-23) Cardoso, Giovanna Monticelli; Bastos-Pereira, RafaelaTwo new species of Diploexochus are described. Diploexochus spinatus sp. nov. from Lapa do Honorato cave, located in the municipality of Iuiu, and Diploexochus obscurus sp. nov. from Água Escura I cave, located in the municipality of Carinhanha, both in the southwest of Bahia State, northeastern Brazil. Both species are likely to occur in caves due to anthropogenic impacts in the surrounding area (such as deforestation) and/or looking for the stable microclimatic conditions found in the subterranean realm. Additionally, D. echinatus is recorded in a cave in the municipality of Rurópolis, Pará State, northern Brazil. These represent the first records of the genus for subterranean environments.Item Erebonyx catacumbae, n. gen. et sp.: a blind, troglobitic cricket from Brazil (Orthoptera, Grylloidea, Phalangopsidae)(2021-05-25) Mello, Francisco A. G.; Ferreira, Rodrigo LopesErebonyx catacumbae, new genus and species of a troglobitic phalangopsid cricket are described from Brazil. Few specimens were collected from a limestone cave located in the municipality of Campo Formoso, northern State of Bahia, in a semi-arid zone characterized by the Caatinga vegetation. A brief discussion on troglomorphisms is provided, as well as some ecological remarks and potential threats for this species.Item Three new species of Eusarcus Perty, 1833 (Opiliones, Gonyleptidae) from Brazilian caves(2021) Santos-Júnior, Gilson Argolo; Ázara, Ludson Neves; Ferreira, Rodrigo LopesThree new species of Eusarcus Perty, 1833 are described from Brazilian caves, increasing the number of species of the genus to 40, eight of which have occurrences in caves. Eusarcus capixaba sp. nov. is described from Lapa do Sítio Paraíso Cave, municipality of Ecoporanga, state of Espírito Santo. Eusarcus marmoreus sp. nov. is described from Caverna Archimides Panssini Cave, municipality of Vargem Alta, state of Espírito Santo. Finally, Eusarcus xambioa sp. nov. is described from Caverna da Explosão Cave, municipality of Xambioá, state of Tocantins. Notes on the species’ habitats and a distribution map are also provided.Item Checklist and identification key to Brazilian species of Triplocania Roesler (Psocodea: ‘Psocoptera’: Psocomorpha: Ptiloneuridae), with four new cave-dwelling species(2021-03-03) SILVA-NETO, ALBERTO MOREIRA; ALDRETE, ALFONSO N. GARCÍA; RAFAEL, JOSÉ ALBERTINO; FERREIRA, RODRIGO LOPESFour species of Triplocania are described and illustrated (T. brancoi n. sp., T. ferratilis n. sp., T. pains n. sp., and T. zairae n. sp.), all based on male specimens collected in caves of the Brazilian state of Minas Gerais. An identification key is presented to the Brazilian species of Triplocania, based on males, together with information on both sexes and distributions.Item Chaimowiczia: a new Iuiuniscinae genus from Brazil (Oniscidea, Synocheta, Styloniscidae) with the description of two new troglobitic species(2021-06-08) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Souza, Leila Aparecida; Ferreira, Rodrigo L.A new genus of Styloniscidae, Chaimowiczia gen. nov., is described with two new species: Chaimowiczia tatus sp. nov. from Gruta do Padre cave (Santana, Bahia) and Chaimowiczia uai sp. nov. from Lapa d’água do Zezé cave (Itacarambi, Minas Gerais). The new genus and species were allocated into the subfamily Iuiuniscinae, hitherto monotypic, by the pronounced rectangular-shaped lateral pereonites epimera, dorsal surface smooth, body outline continuous without a gap between pereon and pleon, and pleonites 3 to 5 developed forming tips. The two species of Chaimowiczia gen. nov. differ in the shape of cephalon antennal lobes, pereonite 1 epimera, pleonite 5 posterior margin and uropod exopod and endopod proportion.
