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 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 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.- Cave lithology effect on subterranean biodiversity: A case study in quartzite and granitoid caves(2020-10) Souza-Silva, Marconi; Iniesta, Luiz Felipe Moretti; Ferreira, Rodrigo LopesPhysical features and lithology variations contribute to promoting changes in faunal composition and richness between caves in Neotropics. Cave lithology effects on biodiversity were reported to iron ore caves in Brazil, however, it is less clear to granitoid and quartzite caves. Hence, based on these two kinds of rocks we correlate invertebrates species richness and composition with some cave features (lithology, the distance between caves, cave extension, number of entrances, entrance size, environmental stability, and altitude). Overall, 1,027 invertebrate species were recorded in 50 sampled caves. From this total, 11 obligate cave species were found. Invertebrate assemblages showed considerable turnover between caves and rock types with a strong contribution of replacement component of beta diversity. Replacement influence was greatest in quartzite caves mainly because of altitude and distance among caves. Furthermore, richness was determined by cave extension in both lithotypes, although this relationship was much more pronounced for the granitoid caves, which contradicts previous studies. The granitoid caves studied here are predominantly structured by stacked blocks with macro and meso anastomosed subterranean spaces that provide an extensive network of interstices with structural characteristics similar to shallow subterranean habitats that may increase in habitat availability and species richness. The study highlight that the lithology-mediated effects of cave extension on richness must be considered for quartzite and granitoid in the ecological and conservational proposal. Furthermore, altitude and distance among caves were important elements determining invertebrate composition.
- New cave species ofPectenoniscus Andersson, 1960 (Isopoda: Oniscidea: Styloniscidae) and an identification key for the genus(2020-10-28) Cardoso, Giovanna Monticelli; Bastos-Pereira, Rafaela; Souza, Leila Aparecida; Ferreira, Rodrigo LopesThe genus Pectenoniscus Andersson, 1960currently presents two described species, one epigean, Pectenoniscus angulatus Andersson, 1960, from Nova Teutônia municipality, Santa Catarina state (Southern Brazil) and the hypogean Pectenoniscus liliae Campo-Filho, Bichuette and Taiti, 2019, found in two caves in the Serra do Ramalho karst area (Carinhanha municipality), Bahia state (northeastern Brazil). 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.
