背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 11 - 14; 脊椎骨: 41 - 43. Differs from all other Mystus sensu stricto by its strongly demarcated, narrow, midlateral longitudinal dark stripe (straddling the lateral line canal), and in having base of outer mandibular barbels slightly behind, rather than in front of, a line vertical to posterior margin of labial rictus. Adipose fin relatively short, originating at a distance of about one eye diameter posterior to dorsal fin and extending only a short distance onto caudal peduncle (Ref. 10418). Total gill rakers 24-28 (Ref. 12975). Adipose fin base longer than anal fin base, originating slightly behind dorsal; cranial fontanel extending posteriorly to base of occipital process (Ref. 43281).
用它的轮廓分明的，狭窄的，和侧面中央的纵向深色的斑纹 (跨立侧线管) 有别于所有的其他 Mystus sensu stricto, 而且些微地有外部颚的触须的基底后面, 而不是在,之前一条线垂直的对唇口裂的后缘。脂鳍相当短的, 起点在大约一眼直径的距离在背鳍后面而且在尾柄之上只有延伸短的距离.(参考文献 10418) 总鳃耙 24-28.(参考文献 12975) 脂鳍基底长度超过臀鳍基底, 些微地开始之后背部的; 头盖的囟门对后头骨突起的基底向后延伸.(参考文献 43281)

Facultative air-breathing in the genus (Ref. 126274); Adults occur in medium to large-sized rivers and flooded fields (Ref. 12975). Feed on insect larvae, fish scales and other fish body parts, as well as plant debris. Breeding habits and seasonal movements are unknown (Ref. 12693). Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).

出现于中到大型的河与被水淹没的田野。 (参考文献 12975) 吃昆虫幼生，鱼鳞与其他的鱼身体部份, 以及植物残枝。繁殖习惯与季节性的运动是未知的。 (参考文献 12693)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00359 - 0.01926), b=2.95 (2.78 - 3.12), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

营养阶层 (Ref. 69278): 3.5 ±0.56 se; based on food items.

回复力 (Ref. 120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Assuming Fec < 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

价格分类 (Ref. 80766): Unknown.
