Diagnostic characters: dermal sac encloses most of body; mass of spongy tissue above trunk from late preflexion stage; supraocular, parietal and posterior preopercular spines finely serrate by late flexion stage; 6-8 melanophores along ventral midline of tail, between myomeres 7-15. Sequence of fin formation: caudal (4.8-7.7 mm); pectoral (5.4-8.5 mm); dorsal (5.5-9.0 mm); anal (5.5-9.0 mm); pelvic (7.7-8.2 mm). Larvae are present in coastal waters off Sydney (NSW) from May to December (Ref. 33622), and Tasmanian coastal waters from October to February (Ref. 35142, 35143). |
