Oldham's leaf turtle

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]

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]

In Germany, a case of hybridization between a male Cyclemys (oldhamii) shanensis and a female Chinese stripe-necked turtle has been described.[8]
