Type locality.

Santo Inácio, state of Bahia, Brazil.

Distribution.

Caatinga endemic species. It is registered in the states of Bahia, Minas Gerais, and Sergipe. It is widespread in the Caatinga and occurs along four ecoregions (Table 1 ; Appendix S3). Distributed in low to high elevation areas (218-1,085 m a.s.l.), with annual mean temperature 20 to 25°C, and average annual rainfall between 492 and 980 mm.

Ecological notes.

Terrestrial and diurnal ( Arias et al. 2011a). The microhabitat most used by juveniles and adults was leaf litter under bush, followed by leaf litter under herbaceous vegetation. Diet based mainly on arthropods, being Isoptera , Araneae , and Coleoptera the most representative items ( Xavier et al. 2019), also with record of cannibalism (Oliveira et al. 2017). Oviparous, no detailed data is known about the number of eggs laid by the species, but it could be similar to other Ameivula ( Mesquita and Colli 2003; Sales and Freire 2016).
