Lissemys is a genus of softshell turtles in the subfamily Cyclanorbinae of the family Trionychidae. The genus is indigenous to southern Asia.
Several extinct fossil species have been described for this genus, such as Lissemys piramensis Prasad, 1974, from Piram Island, India, but these are largely considered nomen dubia.[3][4] However, the extant Indian flapshell turtle (L. punctata) is known from fossils from as early as the Miocene.[5]
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Lissemys.
