| Diagnosis |
Diagnosis: Dorsal fin XII-XIV, 18-21, notched between spinous and segmented-ray portions; anal fin II, 20-21; pectoral rays 13-15 (usually 14); pelvic fin I, 3; caudal fin, procurrent rays 7, segmented rays 13. Vertebrae 12 + 25-27. Orbital cirrus simple and slender, may have a short lateral branch, less often up to 4 branches; nasal cirri short and palmate, may rarely have more than 6 branches; nuchal cirri simple and slender, may have a single branch or a ragged edge. Mandibular pores 6. Dorsal lips margin entire, ventral margin crenulated. Occipital crest absent, but large males have a low thin ridge (less than 1.8 mm); no crest or ridge in females (Ref. 9962). |
