Abstract

A new species of the genus Sibon is described based on four specimens from Parque Nacional Natural Munchique, department of Cauca, Colombia. The new species differs from all members of the S. annulatus and S. nebulatus groups because it has an ocellate pattern, which places it into the S. argus species group. It differs from S. argus by having non-protuberant eyes, fewer ventrals, subcaudals, and total segmental counts; and it differs from S. longifrenis by having fewer segmental counts in males and females, only six supralabials and postmentals absent. Additionally, it differs from both species due to its smaller body size.
