Cave-dwelling gastropods (Mollusca: Gastropoda) of Brazil: state of the art and conservation

Phylogenetic position of the relict South American genus Idiopyrgus Pilsbry, 1911 (Gastropoda, Truncatelloidea), with the description of two new cave species

“…Nevertheless, the lack of body pigmentation and the translucent shell of some specimens (Fig. 2A-H) are possible troglomorphisms, i.e., morphological traits typically observed in cave-dwelling gastropods (Christiansen 2012;Trontelj et al 2012;Salvador et al 2022).…”

“…Besides the translucent shell and lack of body pigmentation, the smaller body size of I. minor sp. nov. can also be interpreted as a possible troglomorphism, given that miniaturization is common in cave organisms, including snails (Christiansen 2012;Salvador et al 2022).…”

Taxonomic study on a collection of terrestrial and freshwater gastropods from caves in Bahia state, Brazil, with the description of a new species

“…Bahia also has numerous limestone and siliciclastic caves that have been tagged as hotspots for both terrestrial and freshwater invertebrates (tRajano & Bichuette 2009). The caves in Bahia are still largely unexplored regarding their molluscan fauna, but they should likewise harbor a wide range of potentially endemic snail species (SalvadoR et al 2022b). Indeed, a few previous works have reported some gastropod species from caves in Bahia, including new species (e.g., SiMone 2015, SalvadoR & SiMone 2016, SalvadoR et al 2022a), but the only more thorough molluscan survey of caves in Bahia state to date is that of SalvadoR et al (2017).…”
