We reviewed the distribution of Dendropsophus columbianus and introduce three new marginal localities for the upper Patia River basin, the western slopes of the Central Cordillera (Quintana, Popayan municipality) and the western slopes of the Western Cordillera in Department of Cauca, Colombia. The Patia River record extends its distribution 40 km airline south to previous known records and Quintana record extends the altitudinal distribution in 160 meters. One locality of these records constitutes also the lowest confirmed elevation known for the species (700 m a.s.l.) in the Andean region and the validation of the distribution of the species in different river basins (Patia and San Joaquin rivers). We also reviewed extra-distributional records from two localities (Quimari and Guapi) in the Caribbean and Pacific regions of Colombia, available in literature. Specimens from Quimari were re-identified as D. phlebodes , whereas the locality of specimens from Guapi is considered here dubious. Using validated localities, we built a distribution model corroborating its high association to Andean ecosystems in the Western and Central cordilleras of Colombia. The potential distribution of the species extends from Narino to Antioquia following the Cauca River basin. Although the model shows that the presence of D . columbianus in Antioquia and Narino is likely, the northern and southern boundaries of the species distribution is unclear due to the absence of records. We hope that the results of future expeditions enable to verify the presence of the species in those regions.
