This species is distinguished by the following characters: body relatively deep and laterally compressed, greatest body depth 2.5-2.8 in SL; interorbital region convex; mouth terminal, jaws about equal; anterior end of upper lip without a thick fleshy protrusion; maxilla with or without scales and without longitudinal ridges; teeth in jaws caniniform to villiform; gill rakers of first gill arch 5-11 + 18-20; soft rays of dorsal fin usually 10, in anal fin 8; lateral line scales 70-72; caudal fin forked. Colour bright blue; broad yellow band over most of dorsal half of body, including most of caudal pedincle fin (Ref. 9821, 90102).
