Abstract

Channa nachi, a new species of snakehead from Meghalaya, Northeast India, is distinguished from its congeners by a creamish-yellow to pale-brown coloured anterior and bluish posterior half of body; sides with 10–12 obliquely-arranged, pale-brown, saddle-like bands; translucent orange pectoral fin with 2–3 faint orange or brown bands; and with a COI genetic divergence of 9.7–20.0%. We review the descriptions of C. melanostigma, C. pomanensis, and C. brahmacharyi, and find C. brahmacharyi to be conspecific with C. pomanensis. We provide additional data to distinguish C. melanostigma and C. pomanensis, and conclude that C. brahmacharyi is a junior synonym of C. pomanensis.
