Distribution and habitat. Gymnodactylus amarali is distributed in the eastern portion of Cerrado and in open vegetation enclaves of southeastern Amazonia (Fig. 2). It is endemic to Brazil, where it is known from the states of Tocantins, Mato Grosso, Goiás, Maranhão, Piauí, Bahia (Cerrado), and Pará (Amazonian region). Gymnodactylus amarali is terrestrial/semifossorial and diurnal, inhabits both cerrado vegetation and rocky fields (campos rupestres), where it is usually found under rocks, in rock crevices, inside (holes) of termite nests, and occasionally moving on the ground (Colli et al. 2003 —identified as G. geckoides amarali; Vitt et al. 2007—identified as G. carvalhoi).
