Geographic Range [top]

Range Description:	Data gathered between 1994 and 1998 indicates that T. schlegelii is widespread, although at a low density, throughout large areas of Sumatera, Kalimantan, and Sarawak, and still persists in peninsular Malaysia. Current information and sightings are now available from 39 localities in 10 different river drainages. Sebastian (1994) notes an additional three drainages in Borneo where the species is reported.
Countries:	Native: Indonesia (Kalimantan, Sumatera); Malaysia (Peninsular Malaysia, Sarawak) Regionally extinct: Thailand
