Schistura devdevi (HORA, 1935)

Saddleback Loach

January 8th, 2013 — 2:38pm

Type locality is ‘Eastern Himalayas; small streams below Darjeeling and Sikkim, India’, and this species is only known with certainty from upland parts of Assam, Sikkim, Arunachal Pradesh and West Bengal states in northern India.

Records from Nepal apparently require confirmation while it may also occur in Bhutan.

The latter describe S. scaturigina as possessing a yellowish-white body with 12 transverse, triangu…
