Thamnodynastes hypoconia (Cope, 1860) “Jararaquinha”

(Figs. 19.5 and 31.4)

First record in the Caatinga. The few records for this species were from the states of Piauí, Bahia and Minas Gerais. It was recorded only in areas with elevation lower than 800 m. It also occurs in the Atlantic Forest, Cerrado, and Pampas regions (Marques et al. 2001; Bérnils et al. 2008; Nogueira et al. 2010, 2011). In the Caatinga it probably inhabits open areas including wetlands and grasslands close to water bodies, as recorded in other portions of its range (Recoder & Nogueira 2007; Valdujo et al. 2009; Recoder et al. 2011; Nogueira et al. 2011). It has semiarboreal habits, is nocturnal and feeds on frogs and lizards (Marques et al. 2001).
