The Burmese flapshell turtle, lives in the Irrawaddy and Salween rivers of Myanmar, and occurs in northeastern Thailand, and possibly in Yunnan Province, China (Kuchling, 1995). It has an olive-brown to brown carapace with some dark spotting (in juveniles) or reticulations (in adults), and the first peripheral is smaller than the second. The head is olive to brown with an indistinct dark stripe extending backward from each orbit and another passing backward between the orbits. Some experts[who?] believe it to be a subspecies of Lissemys punctata rather than its own species.
