This species is distinguished by the following characters: short maxilla, its posterior tip not reaching to posterior margin of the opercle; first supramaxilla elongated, longer than half length of second; abdomen is covered with 5-8 + 9-10 = 14-17 keeled scutes; scutes anterior to pectoral fin absent; 1UGR (upper gill rakers of first gill arch) 15-18, 1LGR (lower gill rakers of first gill arch) 20-23, 1TGR (total gill rakers of first gill arch) 36-40; 2UGR 12-15, 2LGR 20-23, 2TGR 33-38; 3UGR 10-13, 3LGR 12-14, 3TGR 23-27; 4UGR 9-11, 4LGR 9-12, 4TGR 18-22; no distinct black blotches on the dorsal fin; caudal peduncle is rather deep, 10.1-11.5% (mean 10.5%) of SL, and short 8.7-10.4% (usually shorter than 10%; mean 9.3%) of SL; pre-dorsal-fin is short, 48.0-50.4% of SL; snout is short, 3.9-4.8% of SL; body elongate, 23.0-26.9% (rarely 21.2%; mean 24.5%) of SL (Ref. 129422). |
