Channa aurantipectoralis, a new species of snakehead of the C. gachua species group, is described from Karnaphuli drainage of Mizoram, India. The species is immediately distinguished from all other snakehead species by its unique coloration in life, specifically its brightly-coloured orange pectoral fins, which lack any spots or stripes; and by the presence of a dark V-shaped blotch on the dorsal surface of the head. It can be further distinguished from all other species of the genus by the combination of the following characters: presence of pelvic fins, a large scale on the ventral surface of the lower jaw, 51-64 lateral-line scales, 34-37 dorsal-fin rays, 23-25 anal-fin rays, 13-14 pectoral-fin rays, 5½-6½ /1/ 7½-8½ transverse scale rows, and the absence of scales on the gular region.
