Erythrolamprus maryellenae Dixon, 1985

(Figs. 14.7 and 27.2)

Recorded at a single locality in the Diamantina Plateau, municipality of Mucugê, Bahia State, 983 m elevation. It was previously known only in the Cerrado region and is considered endemic to this domain, found mostly in riparian, open areas (Nogueira et al. 2010). Its presence in our study region seems to be restricted to campos rupestres and other cerrado associated grasslands in isolated highlands inside the Caatinga. It has terrestrial and semi aquatic habits, is diurnal, and feeds on vertebrates (Dixon 1989, França et al. 2008).
