简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 57-68; 臀棘 0; 臀鳍软条: 43 - 53; 脊椎骨: 50 - 52. Diagnosis: head rather rectangular in dorsal outline; snout broadly rounded; frontal fontanelle long and narrow (`knife-shaped'); occipital fontanelle oval-shaped (Ref. 248). "Dermosphenotic" and supraorbital bones fused (Ref. 248), closing up early in the ontogenetic process (Ref. 57129). Pectoral spine slightly curved, showing strong downward pointed serrations on its inner side and relatively small downward pointed serrations on its outer side; openings of secondary canals of lateral line appear as irregular white spots on body (Ref. 248). 43-53 anal fin rays, 57-68 dorsal fin rays (Ref. 57129).
Coloration: live fish: olivaceous-brown on back, olivaceous on sides and whitish on belly (Ref. 57129). Preserved specimens: dark brown on back and sides, belly pale brown; several specimens have a yellowish spot at pelvic-fin bases; caudal fin with a few alternating dark and light vertical bars; dorsal and anal fins sometimes light-edged (Ref. 57129).
头部相当矩形在背部的轮廓中; 吻宽广地圆的。 额骨囱门长而狭窄的;(刀状的') 后头骨囱门椭圆形的。 那皮蝶骨的' 与上眼窝骨被融合。 胸棘些微地弯曲,显示强的向下尖锯齿在它的内部侧边与相当小的向下尖锯齿在它的外部侧边。 侧线的第二感觉管的开口在身体上呈现不规则的白色斑点。
Facultative air-breathing (Ref. 126274); Nothing is known about the biology of this catfish (Ref. 78218).
