Chironius bicarinatus (Wied, 1820) “Cobra-de-cipó”

(Figs. 11.3 and 24.1)

It was recorded in states of Ceará, Paraíba, Sergipe, and Bahia. It was found mostly in high altitudes (720 to 920 m elevation), with records in low altitudes only next to northeast Atlantic Forest (188 to 460 m elevation). It also occurs in Atlantic Forest, Cerrado, and Pampas (Marques et al. 2001, 2005; Bérnils et al. 2008; Nogueira et al. 2011). It seems be restricted to forested areas in Caatinga, in highland forests on Ceará and Paraíba States, and along the contact area with the Atlantic Forest. It has semi-arboreal habits, is diurnal, and feeds mostly on frogs (Marques et al. 2001).
