Chinese 'Red' Mahseer (Tor sinensis)

Tor sinensis, the Chinese or Red mahseer is a species of mahseer native to the Mekong River.^[1][2] It is known with certainty only from Yunnan, China; reports from Cambodia, Laos, and Thailand require confirmation.^[1]
It is one of four currently valid species described from China, the others being Tor laterivittatus (dark-striped mahseer), Tor polylepis (multi-scaled mahseer), and Tor yingjiangensis (Yingjiang mahseer).

Description

Tor sinensis grows to 46.5 cm (18.3 in) in standard length. Juveniles are silvery, but adults and subadults have a deep, dark midlateral stripe. The body is darkish above and brownish beneath. Pectoral, pelvic, and caudal fins are deep red.^[2]

Maurice Kottelat is among those who claim that insufficient work has been done on establishing specimens from confirmed species populations when identifying mahseer species.^[3] This is common across the species of Southeast Asia in particular, and includes claimed distinctions between Tor sinensis and Tor laterivattatus.
