簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 4; 背的軟條 (總數) : 9 - 10. Diagnosis: D IV, 9-10; A 2-3/6; lateral line scales (29) 30-33; circumpeduncular scales 12 or 14. Upper profile convex, lower one almost straight; Body depth 24.5-29.8 % of SL. Snout narrowed anteriorly, sometimes almost pointed; in large-sized specimens it is about twice the length of the eye diameter. Lower lip smooth and without median lobe. The anterior pair of barbels is absent in most specimens, may be present but rudimentary (Ref. 57642).
