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.Item A new species of Chaimowiczia from the karstic Serra do Ramalho plateau, Brazil (Oniscidea, Synocheta, Styloniscidae)(2022-03-29) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Ferreira, Rodrigo LopesChaimowiczia belongs to the subfamily Iuiuniscinae, family Styloniscidae, and is currently composed of two troglobitic species: C. tatus and C. uai, both occurring in Brazil. A new species of Styloniscidae found in Brazil (Bahia state, Serra do Ramalho, Serra Verde cave) was allocated into this genus by the antenna flagellum with three articles; rectangular-shaped lateral pereonites epimera not apically acute and apex of pleopod 2 endopod with an acute tip and an acute or rounded lobe directed outwards. The new species, C. obybytyra sp. nov., is here described and rises to 25 the number of troglobitic styloniscidean species known for Brazilian caves.Item Coarazuphium auleri sp. n. (Carabidae: Zuphiini), a new troglobitic ground-beetle in Central-Western Brazil(2021-12-12) Pellegrini, Thais Giovannini; Bichuette, Maria Elina; Vieira, LetíciaABSTRACT In this paper, we describe Coarazuphium auleri sp. n. Until now, the species occurred in a single limestone cave, located at Nobres municipality (state of Mato Grosso – Central-Western Brazil). The new species comprises an apterous species from the genus Coarazuphium with the complete absence of hindwings, eyes are composed of very reduced eyes-scars, depigmentation and ommatidia are not evident. We also provide an updated key for species identification of Coarazuphium from the most recently published one. We followed the criteria of IUCN and classified the species as Critically Endangered – CR, IUCN criteria B1ab(iii)+2ab(iii), since the species has a restricted geographical distribution; estimated occurrence length <100 km2; population in few locations and with a continued decline in area, extent, and quality of habitat. According to Brazilian law, the existence of a critically endangered species places the Lagoa Azul cave as one of maximum relevance.Item Chaimowiczia: a new Iuiuniscinae genus from Brazil (Oniscidea, Synocheta, Styloniscidae) with the description of two new troglobitic species(2021-06-08) Monticelli Cardoso, Giovanna; Bastos-Pereira, Rafaela; Aparecida Souza, Leila; L.
