Espinas dorsales (total) : 0; Espinas anales: 0; Radios blandos anales: 20 - 25. Snout moderate and pointed, tip well above center of eye; maxilla short, tip blunt, failing to reach articulation of lower jaw by about 1/3 eye diameter, not extending behind end of second supra-maxilla; sub-operculum with angular hind margin, not formed into a triangular projection; gill rakers fine and slender. Silver stripe along flank, up to 1.5 eye diameter at widest (Ref. 189). Lacks membrane connecting the gill covers across the isthmus, longer and narrower cheek, higher dorsal and longer pectoral.
