Diagnostic characters: heavy pigment dorsally over head and trunk; pigment laterally along entire trunk to anterior half of tail; single series of 13-16 melanophores along ventral midline of tail. Sequence of fin development: pectoral (- mm); pelvic (4.5-5.5 mm); caudal (4.5-7.5 mm); dorsal (4.5-8.0 mm); anal (4.5-8.0 mm). Body initially elongate to moderate, elongate in juveniles. Head moderate to large, initially lightly compressed, depressed in postflexion larvae. Eyes initially round and laterally positioned, slightly ovoid and dorsally positioned after settlement. Small teeth on premaxilla and dentary by flexion stage. One anterior preopercular and 2 posterior preopercular spines, and a large parietal spine in smallest larva; 5 posterior preopercular spines in postflexion larvae, all retained after settlement. One supraocular spine prior to flexion stage; 1 cleithral spine and infraorbital spines from flexion stage; nasal, pterotic, posttemporal and supracleithral spines by postflexion stage. Gut moderate to long, coiled. Small gas bladder over foregut. Large, wing-shaped pectoral fins, extending beyond anus from flexion stage. Scales form after 30 mm BL (Ref. 34078). |
