E-mail: Abstract: Dunns’ mud turtle Kinosternon dunni is recognized only from a few localities in the drainages of the San Juan,

Baudó and Docampadó Rivers in Chocó, Colombia. We report on the occurrence of the species in three new localities in a different drainage, two in the Atrato River drainage, which flows into the Caribbean Sea, and a third locality in the Gulf of Urabá, in the Colombian Caribbean. These new records extend the range of the species approximately 367 km to the north of the closest previous confirmed record.

It contains three new localities that extend the distribution to a two subfamilies ( and Staurotypinae), of which Kinosterninae is the largest and most varied known location. Two localities correspond to individuals (Iverson 1991), encompassing the genera Sternotherus new drainage and 367.4 km to the north from the closest and Kinosternon. Three species of mud turtles of the Kinosternon occur in South America: K. scorpioides Linnaeus, 1766, K. leucostomum Duméril and Bibron, 1851, and K. dunni have a wide distribution, occurring from Mexico to South America, while K. dunni Schmidt, has a 1947.small Therange first and two is endemic species
