Diagnosis

Dorsal fin III+XII-XIII+8-11 (usually III+XIII+9-10); anal fin I,17-19 (usually 18-19 rays); pectoral fins 15: 2+7+6 (occasionally 3+6+6); lateral line with 14-16 (usually 15) pored scales and 19-23 (usually 20-21) notched scales, notched segment starting next scale row below end of pored segment, below mid-second dorsal fin. Total lateral scales 33; transverse scales 3/5. Vertebrae 10+25. Mandibular pores 3+2+3. Head length 3.1-3.6, body depth 5.4-5.9 in SL;

eye 2.7-3.2 in head length. A medium-sized species of Enneapterygius (less than 30 mm SL). Nape scaled, body scales continuing to bases of dorsal and anal fins; belly naked. Pelvic-fin rays not united by membrane. First dorsal fin equal in height to second, second about 70% of body depth. Simple, lobate orbital and anterior nasal cirri present. Supratemporal sensory canal slightly curved. Tongue triangular and sharply pointed; maxilla reaches vertical through

anterior margin of pupil; broad band of teeth in upper and front of lower jaw; palatines without teeth. Spines of first dorsal fin with small, laterally projecting spinelets (Ref. 57774).
