Natural history

Specimens were found in two caves, Lapa do Baixão and Toca Fria, which are around 18 km apart. Both caves are located in the Iuiu Municipality (Bahia State, Brazil), in the Caatinga biome, and belong to the Bambuí limestone group. Although other caves in the area were also surveyed, specimens were only found at the two type localities. The surroundings of the entrance to both caves are severely impacted, mainly by agricultural activities, extensive cattle and goat breeding (Vasconcelos & Ferreira 2016).
