型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 92-97; 臀鰭軟條: 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).
在有一個方面與 Clarias nieuhofii 種群的同類區分了狹窄的吻 (有一個卵-形狀的頭部當背面看了), 深紫羅蘭色灰色的顏色用白色小斑點在側面,一個狹窄的頭部 (11.7-12.3% SL) 上, 一相當大的在胸棘的前緣上後頭骨突起的頂端與第一背鰭鰭條 (8.1-9.8% SL) 的基底 , 與少數大的鋸齒之間的距離.(參考文獻 55460)
