Épines dorsales (Total) : 5; Rayons mous dorsaux (Total) : 13; Épines anales: 3; Rayons mous anaux: 9; Vertèbres: 27. This species is distinguished from its congeners by the following set of characters: body soft and dusky; bony ridges on the head and fin rays delicate; body scales deciduous; gular region covered with ctenoid scales; pelvic-fin spine smooth on its anterior edge; head depth smaller than its length, 37.2%-38.6% SL or 94.7%-99.2% HL; pectoral-fin length 35.6%-37.8% SL, with tip reaching beyond vertical through anal-fin origin to middle of anal-fin base; abdominal scutes well developed, 12-16; pectoral-fin rays uniformly black, 17-19; gill rakers on outer surface of first arch 6-7 + 1 + 13-14 = 21; pre-dorsal scales 24-27; pyloric caeca 32; moderate body size 230 mm SL (Ref. 133164).
