Pseudoscorpions are small, abundant and diverse arachnids in the Neotropics. In the Colombian Caribbean region, research on the fauna of these arachnids is scarce compared to that of other regions of Colombia. From February 2016 to October 2017, specimens belonging to this group were collected in the department of Sucre, in order to assess its local diversity. The genera Cacodemonius Chamberlin and Dolichowithius Chamberlin, and the species Tyrannochthonius (Tyrannochthonius) amazonicus Mahnert and Ideobisium chapmani Muchmore are reported for the first time in Colombia. Additionally, ecological comments are included and a check-list of species for Colombia is presented
