Type locality of Tor remadevii, Pambar, the southern-most tributary of the River Cauvery in Kerala. It is endemic to River Cauvery, Karnataka, Kerala, Tamil Nadu. Tor remadevii is currently known only from the eastward flowing River Cauvery and its tributaries including the Moyar, Kabini, Bhavani and the Pambar, in the Western Ghats Hotspot of peninsular India (Ref. 123468). Also known from Chambakkad and Koottar regions of river Pambar in Chinnar Wildlife Sanctuary, Kerala, southern India (Ref. 88141).

Status of threat: Critically endangered: following its collapse in recruitment in the main river population during the mid-2000s (Pinder et al. 2015b), the only spawning populations currently known to persist are restricted to a 40 km reach of the River Moyar, Tamil Nadu (Pinder et al. 2018a) and the Pambar River in Kerala. The status is because of the alarming population size reduction and persistent threats (Ref. 123468).
