Maturity: Lm ? range ? - ? cm
Max length : 90.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 130031)
背棘 (總數) : 1; 背的軟條 (總數) : 7; 臀鰭軟條: 10 - 13; 脊椎骨: 50 - 51. Can be differentiated from its congeners by the unique combination of the following characters: head extremely depressed and broad; dorsal spine well ossified, long (11.9-14.8% SL), and with 10-12 serrations on the posterior edge; cream-colored coracoidal region; caudal fin dark grey, with cream procurrent and first principal caudal rays; maxillary barbels reaching to middle of dorsal-fin base (143.7-195.4% HL) (Ref. 38441). Smooth flat skull roof; occipital process reaches basal bone of dorsal fin; 10-11 soft pectoral-fin rays; no stripe on body (Ref. 12693). Presence of white markings on pectoral fin and dorsal fin tips, anterior edge of adipose, upper and lower margins of caudal peduncle and caudal, including filaments (Ref. 43281).
能被與它的同類區別藉著下列特徵的組合: 頭部非常地扁平的與寬的; 很好地鈣化的背棘, 長的 (11.9-14.8% SL), 與具有 10-12 在後緣上的鋸齒; 奶油色的鳥喙骨區域; 尾鰭深灰色的, 藉由乳黃色的前流與第一的主要尾鰭鰭條; 上頜骨觸鬚延伸到背鰭基底 (143.7-195.4% HL) 的中央.(參考文獻 38441) 平滑的平坦頭蓋骨頂部; 後頭骨突起達到背鰭的基骨; 10-11 柔軟胸鰭鰭條; 沒有在身體上的斑紋.(參考文獻 12693) 在胸鰭與背鰭頂端，脂鰭前緣，尾柄與尾鰭的上、下邊緣上出現白色的斑紋, 包括絲狀突起。 (參考文獻 43281)
Lives in large rivers with fast flowing water over muddy substrate (Ref. 56749). Appears to be restricted in the middle reaches of rivers (Ref. 40801). Feeds on insects, prawns and fishes. Sold fresh in the markets (Ref. 33813).
生活在大河。 (參考文獻 33813) 似乎在河的中游中限制。 (參考文獻 40801) 吃昆蟲，蝦與魚。 在市場中生鮮販賣了。 (參考文獻 33813)
