Diagnosis

Diagnosis: head length 34.0-35.2 %SL; snout length 29.3-31.2 % head length; lower jaw length 33.1-34.4 % head length; premaxillary pedicel 26.0-27.6 % head length; lachrymal 18.6-20.0 % head length; interorbital 20.8-23.2 % head length; lower pharyngeal jaw 28.2-28.8 % head length; 14-16 gill-rakers on lower limb of first arch; predorsal distance 37.4-38.5 %SL (Ref. 55898).

Description: dorsal and ventral body profile convex, dorsal more strongly than ventral; head small; snout short and blunt; mouth small; gape inclined at about 20° to horizontal; maxilla extending to vertical at anterior margin of eye; outer oral teeth bicuspid, close-set; inner oral teeth unicuspid, some shouldered tricuspid; 2 series of scales on cheek; upper margin of eye does not touch dorsal head profile; lower pharyngeal jaw normal; posterior median pharyngeal teeth enlarged, but not molariform; gill-rakers on lower limb short (Ref. 55898).

Coloration: Preserved: body color beige; 6-7 faint vertical bars below dorsal fin; bars visible only on upper half of body; dorsal fin pale with irregular grey spots, merged into oblique bars on soft dorsal; dorsal fin tips pale; all other fins pale (Ref. 55898).
