Diagnosis: Dorsal fin XII, 14, membrane attached to caudal fin, with deep notch above last spine, first spine about equal to second; anal fin II, 16; pectoral rays 15; pelvic fin I, 4; caudal fin procurrent rays 10-12. Vertebrae 10 + 20. Last epipleural rib modally on vertebral centrum 19. LL, without scales and scalelike flaps; LL tubes 1-7, canal ends on caudal-fin base. Lower lip smooth mesially, plicate laterally. Upper lip crenulae 36-43. Gill rakers 26-27. Cephalic sensory pore system complex, no pores at the extra interorbital position. Midsnout pores present. Cirri, supraorbital 12-26, nasal 10-18; nuchal cirri 36-42, in 4 groups, ventralmost group borne on a slightly expanded flap. Body spots, extending to basal half of dorsal, anal and caudal fins in females but not in males (Ref. 529). |
