We report the first specimen-based records of Heosemys spinosa (Gray 1830) from Myanmar, validating earlier assumptions of its occurrence within the country. Our records consist of 5 living H. spinosa examined at Kan Baw Gyi Village in Tanintharyi Region of southern Myanmar. These specimens originated from seasonally inundated lowland riparian wetlands near the village where we examined them. Potential threats to H. spinosa in southern Myanmar include subsistence and commercial harvesting and, most importantly, the widespread conversion of natural forests to oil palm plantations.
