Lameirao , Buritirama, state of Bahia, Brazil. Distribution. Caatinga endemic species. It is recorded only in the state of Bahia. It shows restricted distribution in the Caatinga and occurs along one ecoregion (Table 1 ; Appendix S3). Distributed in medium elevation areas (503-600 m a.s.l.), with annual mean temperature 24°C, and average annual rainfall between 942 and 953 mm. Ecological notes. Fossorial and nocturnal ( Recoder et al. 2022 ). Recorded to occur in a sandstone plateau, characterized by white sandy soils, on the east side of Serra do Estreito. The vegetation is a short xeromorphic caatinga vegetation with sparse trees, shrubs, cacti and clumps of bromeliads with scattered spaces of bare sand. Individuals were found buried in sand under leaf litter in shaded microhabitats ( Recoder et al. 2022 ). Diet based mainly on arthropods, no information about the preferred items on the diet of this species is known. Oviparous, no detailed data is known about the number of eggs laid by the species, but it could be similar to other Calyptommatus species ( Rodrigues 1991a ).
