Dunn’s Mud Turtle is one of the least known species from the family Kinosternidae. It was known from only approximately ten localities in the Departamento del Chocó near the Pacific coast of western Colombia. Since the work by Medem in the early 1960’s less than five individuals had been observed or collected in the field. Additionally, the species is considered to be threatened because of its small geographic range and rarity, because it is consumed locally, and the increasing pressure on its habitat from logging and gold mining. Considering the urgency to collect information on the distribution and population status of the species, we started a survey in 2011 sponsored by a TSA seed grant in Colombia, and in collaboration with local institutions. We present the preliminary qualitative results of this survey and the project that was initiated in the region. We visited six localities in the Departamento del Chocó, at sites where the species had been previously recorded and at sites outside the known range where it was suspected to occur according to reports from local people. In each locality, we set baited traps or hand captured individuals attracting them with bait for three consecutive nights. We did not find the species at localities with previous records. However, we recorded the species in two new localities, Rio Quito and Samurindó, in the drainage basin of the Atrato River, which flows into the Caribbean, as opposed to all previous records, which are in the Pacific drainage. Most individuals were captured in a marshy area dominated by palm trees of the genus Euterpe. Animals were active during the night, and were all captured in the water (<1.5 m depth). The sex ratio was 7 (males):9 (females):1 (juvenile). The maximum size and weight recorded was 180 mm carapace length and 800 g, for a male. The species was sympatric with K. leucostomum and Rhinoclemmys melanosterna. A project was started in collaboration with local organizations to monitor the population identified, collect information on the natural history of the species, and develop a local group for the study of the chelonians of the region.
