Body and head shallow, becoming moderately deep in large adults, body depth 26.6-37.1%SL. Eye large. Predorsal scales reaching forward to above midpoint between hind margin of eye and hind edge of preopercle. Cheek scales reaching forward to below anterior extent of orbit; moderately narrow naked margin along free edge of preopercle; subopercle with 5-9 uniserial scales reaching forward to below centre of eye. Lateral-line scales usually without accessory branches associated with sensory pore. Upper jaw with two pairs of prominent ventrally directed canines anteriorly, anteriormost about twice the size of second; upper jaw without posterior canines. Lower jaw with two pairs of prominent anterior canines, anteriormost much smaller than second; second pair strongly curved laterally.
Caudal fin broadly wedge-shaped, upper and lower corners each produced into slight lobe. Pectoral fin rather pointed dorsoposteriorly, with lower ray produced, giving hind margin of fin lunate appearance.

Colour

Juveniles pale with narrow dusky midlateral stripe on sides extending from opercular margin onto caudal fin; small triangular dark mark extending from lateral stripe above pectoral-fin base toward lateral line. 
Initial and terminal phase individuals pale with hazy angled dark slash on side about midway between pectoral-fin base and dorsal profile of side; small dark spot at upper end of pectoral-fin base and short narrow dark mark near centre of hind margin of caudal-fin. 

Fisheries

Etymology

The specific name is from the Latin sugillatum (black and blue spot), in reference to the characteristic marking on the side of this species.
