| Diagnosis |
Diagnosis: Dorsal fin XII, 14, membrane attached to caudal fin, with deep notch above last spine, first spine almost same or slightly higher than second; anal fin II, 15; pectoral rays 15; pelvic fin I, 4; caudal fin procurrent rays 11-14. Vertebrae 10 + 20-21. LL, without scales and scalelike flaps; LL tubes 3-9 (usually 8-13), canal ends below posterior to 13h dorsal ray, usually on caudal-fin base. Upper lip crenulae 36-42. Gill rakers 23-29. Cephalic sensory pore system complex. Cirri, nuchal 35-42, nasal 8-93, supraorbital 12-29; 4 groups of nuchal cirri, each ventralmost group borne on slightly expanded nuchal flap. No pores at extra interorbital pore position. Geographic variation in color pattern exists in females; 2 color patterns in male may exist in the same geographic area; background color brown; yellow to orange iris (Ref. 529). |
