Diagnosis

This species is distinguished by the following characters: dorsal profile moderately convex anteriorly; adipose eyelid well developed, moderate anteriorly, posterior eyelid extends onto eye to rear border of pupil; gill rakers (including rudiments) 6-8 + 15-19 = 21-25; straight part of lateral line with 0-3 anterior scales followed by 27-36 strong, dark scutes; breast completely scaly; vertebrae 10+15; upper jaw with outer row of strong canines widely spaced in adults, and an inner band of small villiform teeth, widest at symphysis; on lower limb of first gill arch jaw with a single row of strong conical teeth widely spaced in adults. Colour in life with adults' head and body silvery olive to iridescent blue-green above, silvery olive to whitish below; small blackish spot, much smaller than pupil diameter, at upper angle of opercle (this spot evident on specimens of about 14 cm fork length); second dorsal fin olive to blackish, the lobe with a white tip (white tip becomes more obvious with increasing size) (Ref. 9894).

Description: Anal and caudal fins yellowish to black; body oblong and compressed; ventral profile slightly convex; pectoral fins falcate; anal fin with 2 detached spines (Ref. 2334, 90102).
