Diagnosis

This deep-bodied species is distinguished from other siganids in that the whole of the sides of the body with the possible exception of the belly and a narrow strip adjacent to the base of the spinous dorsal fin (where a row of bronze spots may occur), are decorated with horizontal, parallel bronze bands extending the full length of the sides from nape and opercular slit back to and below the large yellow spot below the base of the soft dorsal fin; majority of these lines on the sides are complete (uninterrupted) along their length (Ref. 95994).
