Systomus chryseus, new species, differs from its relative species in having an unusually elongated body, golden to yellowish golden color on flanks, pectoral, pelvic and anal fins orange red; pectoral fin long and its tip reaches origin of ventral fin; lateral line scales 29-30 and pre dorsal scales 11. Systomus rufus, new species, differs from its congeners in having a deeper body; dorsal fin situated nearer to caudal fin base than snout tip and a little behind ventral origin; dorsal fingreen and other fins red; 11-12 pre dorsal scales, 30 lateral line scales and 6½ scales between lateral line and dorsal fin base. The new species of fishes are described and compared with its related species.
