Basin Ground Snake

description

(Fig. 12 F) The combination of cryptozoic habits of species and shortfalls of biological knowledge on Amazonia usually provide challenging cases in defining distributional limits for the snake genus Atractus Wagler, 1928 (Fraga et al., 2017). For instance, A. poeppigi (already considered a synonym of Atractus elaps Günther, 1858 [Dixon et al., 1976]) is a representative of an Atractus species with an irresolute distribution, composed by patchily distributed localities of occurrence. With occurrence records ranging from the Andean foothills to the central lowland Amazonia (Nogueira et al., 2019), A. poeppigi can be considered widely distributed, and records in the RBJ (three individuals) help to fill some of the knowledge gaps in its distribution.
