背棘 (总数) : 0; 背的软条 (总数) : 92 - 97; 臀鳍软条: 80 - 86; 脊椎骨: 76 - 83. Distinguished from congeners of the Clarias nieuhofii species group in having a narrow snout (with an egg-shaped head when viewed dorsally), dark violet grey coloration with small white spots on flanks, a narrow head (11.7-12.3% SL), a relatively large distance between the tip of the occipital process and the base of the first dorsal fin ray (8.1-9.8% SL), and few large serrations on the anterior edge of the pectoral spine (Ref. 55460).
在有一个方面与 Clarias nieuhofii 种群的同类区分了狭窄的吻 (有一个卵-形状的头部当背面看了), 深紫罗兰色灰色的颜色用白色小斑点在侧面，一个狭窄的头部 (11.7-12.3% SL) 上, 一相当大的在胸棘的前缘上后头骨突起的顶端与第一背鳍鳍条 (8.1-9.8% SL) 的基底 , 与少数大的锯齿之间的距离.(参考文献 55460)
