Abstract: Atractus modestus was described based on a single specimen from western Ecuador, and since its original description there have been no further records for this species. During the examination of Ecuadorian collections, we found additional specimens of this poorly known snake. In this paper, we redescribe the holotype of A. modestus, describe the hemipenis and report new specimens, localities, and data on meristic and morphometric variation in the species. We also compare and diagnose this species from all others members of this highly diverse genus.
