Dorsale zachte stralen (totaal) : 14 - 15; Anale zachte stralen: 30 - 33; Wervels: 40. This species is distinguished by the following characteristics: short maxilla, posterior tip not
reaching to posterior margin of opercle; first supramaxilla is elongated, longer than half length of second; abdomen covered with 4-6 + 8-10 = 12-16 keeled scutes; no scutes on anterior to pectoral fin; 1UGR (upper gill rakers of first gill arch) 16-18, 1LGR (lower gill rakers of first gill arch) 21-23, 1TGR (total gill rakers of first gill arch) 38-40; 2UGR 13-15, 2LGR 22-24, 2TGR 36-38; 3UGR 11-12, 3LGR 13-15, 3TGR 25-27; 4UGR 10-11, 4LGR 10-12, 4TGR 20-23; no distinct black blotches on dorsal fin; caudal peduncle is narrow [9.3-10.2% (mean 9.7%) of SL] and long (9.7-10.5% of SL); pre-dorsal-fin is long, 50.6-52.0% of SL; snout long, 4.9-5.3% of SL (Ref. 129422).
Body shape (shape guide): elongated; Cross section: compressed.
