Lygophis paucidens (Hoge, 1853) “Cobra-de-cadarço”

(Figs. 16.4 and 29.1)

First record in the Caatinga. Recorded only in three localities, in the states of Piauí and Bahia, in altitudes up to 500 m elevation. It is found mostly in open savannas and grasslands on sandy soils, and is considered a Cerrado endemic snake (Nogueira et al. 2010, 2011). It probably occurs in areas with relictual cerrado enclaves, including those in uplands of the Chapada Diamantina complex. It has terrestrial habits, is diurnal, and feeds on frogs and lizards (Dixon 1989).
