Diagnostic characters: light pigment dorsally on head and anterior of trunk; broad band of melanophores scattered over trunk and tail above anus; singel series of 18-20 melanophores along ventral midline of tail; pigmented stripe from snout to posterior margin of opercle. Sequence of fin development: pectoral (2.6-6.4 mm); pelvic (3.3-6.4 mm); dorsal (3.3-7.3 mm); caudal (3.9-7.0 mm); anal (4.0-7.3 mm). Body moderate, compressed. Head moderate in preflexion larvae, large in flexion and postflexion larvae. Teeth along both jaws by late preflexion stage. Two moderate posterior preopercular spines in early preflexion larvae. Two or three anterior preopercular spines and 1 large parietal spine in preflexion larvae; infraorbital, supraocular, supracleithral and cleithral spines in flexion larvae, and 1 posttemporal, 1-2 pterotic and 1 nasal spine in early postflexion larvae. Gut moderate to long, coiled. Gas bladder above foregut. Large, wing-shaped, pectoral fins, extending beyond anus from flexion stage. Lateral line scales begin to form at settlement. Larvae are present in Lake Macquarie (NSW) from November to May, with peak abundances between January and March (Ref. 33621), and in coastal waters off Sydney (NSW) from October to May (Ref. 33622).
