 Abstract
Channa bhoi, a new species of snakehead fish, is described from the Ri-Bhoi district of Meghalaya, India. It belongs to the Gachua group and differs from all its related congeners in having a combination of the following characters: a unique color pattern consisting of a bluish-gray body with lateral scale rows possessing a single, minute black spot on each scale, visibly arranged as 8–9 horizontal rows of broken lines, more transverse scale rows from post-drop to anal fin, more pored lateral-line scales, and a grayish-yellow pectoral fin with 6–8 thin, ochre-yellow to cream bands appearing in a wavy pattern. It differs from all its related congeners by a genetic distance of 3.3–20.4% in the cox1 gene.

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.
