背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 12 - 14; 脊椎骨: 38 - 41. Distinguished from all other Southeast Asian congeners, except Mystus castaneus, M. impluviatus and M. nigriceps by the following combination of characters: a moderately long (29-37% SL), low adipose-fin, uniform body color, fossa on midline of the cranium not reaching to the base of the supraoccipital process and extremely long maxillary barbels that reach beyond the base of the caudal fin (Ref. 55439). Differs from M. castaneus, M. impluviatus and M. nigriceps in lacking a dark triangular mark at the base of the caudal fin. Further differs from M. nigriceps in having a longer (34.3-36.3% SL vs. 26.3-31.4), deeper (6.7-7.5% SL vs. 4.1-6.0) adipose fin and longer pelvic fins (17.6-20.2% SL vs. 13.4-16.7); and from M. castaenus and M. impluviatus in having a more gently-sloping dorsal profile of the head. Differs also from M. impluviatus in lacking (vs. presence) of fontanel on the supraoccipital and having a deeper adipose fin (6.7-7.5% SL vs. 4.7-6.0) (Ref. 55439).
Body shape (shape guide): elongated.
与所有的其他东南亚同类区分了, 除了 Mystus castaneus, M. impluviatus 与 M. nigriceps 以外藉由跟随组合特征: 一个中等长度的 (29-37% SL) 又低的脂鳍,均匀的身体颜色, 在头盖的中在线的窝不延伸到上枕骨突起的基底与达到超过尾鳍基底的非常长颚的触须.(参考文献 55439) 有别于 M. castaneus, M. impluviatus 与 M. nigriceps 在尾鰭基底沒有深色的三角形的標誌。 進一步在有一個更長的 (34.3-36.3% SL vs.26.3-31.4), 較深的 (6.7-7.5% SL vs.4.1-6.0) 的脂鰭與較長的腹鰭有別於 M. nigriceps;(17.6-20.2% SL vs.13.4-16.7) 而且從 M. castaenus 與 M. impluviatus 在有一個方面頭部的比較緩斜坡背面輪廓。 也不同於 M. impluviatus 在缺乏 (vs. 出現) 囟門在上枕骨上而且有一個較深的脂鰭 (6.7-7.5% SL vs.4.7-6.0).(參考文獻 55439)
Facultative air-breathing in the genus (Ref. 126274); Oviparous, distinct pairing possibly like other members of the same family (Ref. 205).
