Drymoluber brazili (Gomes, 1918)
(Figs. 11.8 and 24.4)
It was recorded for states of Piauí, Ceará, Paraíba, and Bahia. Occurs in altitudes between 334 and 1,100 m elevation. It was known from few localities in the Caatinga, but it seems to have wide distribution in the Cerrado region, to which it is considered endemic (Nogueira et al. 2011). This is a very rare snake, with few data on habitat use. Valdujo et al. (2009) report the use of typical cerrado savannas in Emas National Park, and Freitas and Silva (2007) report this species only to cerrado enclaves in Diamantina Plateau. Thus, this snake is probably associated to relictual savanna enclaves in the Caatinga region. The species has terrestrial habits, is diurnal, and feeds on vertebrates (Costa 2010).
