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 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 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 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. Ferreira, RodrigoA 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).

Recent surveys in karstic areas of Minas Gerais and Bahia revealed six new cave species from this genus, which are herein described. Two species occur in Minas Gerais state in the transition between the biomes Cerrado (Brazilian savannah) and Caatinga (mesophytic and xeromorphic forests): Pectenoniscus montalvaniensis n. sp. from Abrigo da Ema cave (Montalvânia municipality) and Pectenoniscusjuveniliensisn. sp. fromGruta do Tabuleirinho cave ( Juvenilia municipality). The other four species were found in Bahia state, in Caatinga biome: Pectenoniscus iuiuensisn. sp. from Baixa da Fortuna cave(Iuiu municipality); Pectenoniscus carinhanhensis n. sp. from three caves in Serra do Ramalho (Carinhanha municipality); Pectenoniscus santanensis n. sp. from Gruta do Padre cave (Santana municipality); and Pectenoniscus morrensis n. sp. from Gruta dos Brejões cave (Morro do Chapéu municipality). Aside from the taxonomic descriptions, we provide ecological notes for each described species, as well as an identification key for Pectenoniscus.
