Xenodon nattereri (Steindachner 1867) Steindachner 1867

Xenodon nattereri (Steindachner, 1867) “Cobra-nariguda” (Figs. 20.3 and 32.3) The single record of this species on Caatinga is from municipality of Rio de Contas, Bahia State (Argôlo 2002). This area is part of Diamantina Plateau complex, 1,050 m elevation. IIt occurs widely in the Cerrado, from where it is considered endemic (Nogueira et al. 2010, 2011), and associated to sparse savannas and grasslands (see França et al. 2008; Sawaya et al. 2008; Valdujo et al. 2009). We have no information on habitat use in the Caatinga but we believe ths species is found in Cerrado vegetation enclaves (incuding campos rupestres) in the Diamantina Plateau, as it is know only from grassy open areas in the Cerrado (Sawaya et al. 2008; Valdujo et al. 2009; Nogueira et al. 2010). It has terrestrial habits, is diurnal and feeds on lizards and squamate eggs (Sawaya et al. 2008).
