Oldham's leaf turtle (Cyclemys oldhamii) is a species of turtle in the family Geoemydidae.

Etymology

Both the specific name, oldhamii, and the common name, Oldham's leaf turtle, are in honor of Thomas Oldham, Superintendent of the Geological Survey of India.^[5] The generic name Cyclemys comes from the Greek κύκλος (kyklos, meaning 'round' or 'circle', referring to the shape of the carapace) and εμύς (emys; 'freshwater turtle').^[6]

Geographic range

C. oldhamii is found in Bangladesh, in the terai of mizoram, in Myanmar, Thailand, Vietnam, West Borneo, Sumatra and Java. In addition, Cyclemys oldhami shanensis – sometimes considered a distinct species due to its shell pattern, oft described as looking similar to aged meat - occurs from central Myanmar to Thailand and Cambodia. The type locality was originally given as "Mergui and Siam", and restricted to Mergui by Smith (1931).^[7]
