Oreichthys warjaintia, a new species of cyprinid fish from Meghalaya, India (Cypriniformes: Cyprinidae)

Oreichthys warjaintia, new species, is described from the Pyrngang stream (Surma–Meghna basin), Meghalaya, northeast India. It can be distinguished from all known species within the genus Oreichthys in having the following combination of characters: complete lateral line with 25–27 pored scales, 13 branched pectoral‐fin rays, 5–5½ branched anal‐fin rays, 14 rows of papillae on suborbital, ½3/1/2½ scale rows in transverse line on body, presence of a black blotch on caudal‐fin base, and in the coloration of dorsal, caudal, and anal fins. Oreichthys warjaintia is distinct from all known Oreichthys species for which mitochondrial cox1 sequence data are available by a raw genetic distance ranging from 8.3% to 11.1%.
