简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 70-86; 臀鳍软条: 54 - 71; 脊椎骨: 58 - 65. Diagnosis: head relatively long (Ref. 248, 57129) and flattened, its length 24.8-28.6% SL (mean 26.2)(Ref. 57129, 81644). Frontal fontanel short and wide (Ref. 57129, 81644), "sole-shaped" (Ref. 248), 1.5 times as long as wide (Ref. 81644). Lateral cephalic bones (dermosphenotic and supraorbital) becoming contiguous already in young individuals (between 70 and 80 mm SL)(Ref. 248, 57129, 81644). First gill arch with 11-19 gill rakers (Ref. 57129, 81644). Color pattern usually uniform, occasionally a marbled pattern consisting of various dark brown spots on a light-brown background; head broad and pointed in dorsal outline; tooth plates broad; suprabranchial organ well developed although not completely filling the chamber (Ref. 248). Vomerine tooth band a little less short than premaxillary tooth band; pectoral spine serrate only along anterior margin; flank neuromasts arranged in a regular pattern (Ref. 81644).
Coloration: no information on colour in life (Ref. 57129, 81644). Most preserved specimens uniformly coloured: back and sides light to dark brown, belly beige-white; some specimens have a marbled pattern, with numerous black spots against a lighter background on back and sides, while the belly is beige to yellowish (Ref. 57129, 81644).
彩色斑纹通常均匀的; 偶然地包含在淡褐色背景上的各种不同的深褐色的斑点的一个大理石花纹的图案。 头部长的，宽的与尖的在背部的轮廓中。 那皮蝶骨的与上眼窝骨在一个个体发生的早阶段中合并在一起。 额骨囱门唯一的-形状的'. 齿板宽的。 鳃前的器官发展良好的虽然不完全地填充腔室。
Facultative air-breathing (Ref. 126274); Ecology, food and breeding: unknown (Ref. 248).
