sp. nov. is considered a troglophilic species rather than a strict troglobitic one. The region of Central is characterized by a dry vegetation type (Caatinga) and the caves represent good shelters for these animals, given their high-humidity microhabitats. Few collections were conducted outside the caves and, as such, this species occurrence outside subterranean habitats was not tested. Nevertheless, the lack of body pigmentation and the translucent shell of some specimens (Fig.
