Abstract
Abstract: We redescribe Atractus punctiventris based on the examination of its holotype, two topotypes, and two additional specimens recently collected. We describe two new species of Atractus with 15 dorsal scale rows, previously confused with Atractus insipidus, from the eastern and western portions of Brazilian Amazonia, respectively. The new species are recognized on the basis of unique combinations of morphological characters. We compare Atractus punctiventris and the two new species with all congeners from most lowland provinces of cis-Andean South America. We discuss potential affinities of the three species, mainly by sharing exclusive hemipenial traits with congeners placed in different phenetic groups, and allocate them to distinct species groups of Atractus.
