背棘 (總數) : 1 - 2; 背的軟條 (總數) : 6 - 7; 臀棘: 0; 臀鰭軟條: 7 - 10; 脊椎骨: 34 - 39. Diagnosis: This species is distinguished from most of the other species by its more slender form, with standard length larger than 8 times body depth, by the short humeral process, less than 20% of the lateral head length and by the possession of only two or three barbs on the pectoral-fin spines (Ref. 86935). It is distinguished from Zaireichthys mandevillei by the large eye, more than one sixth of the head length, vs. 12 times in head length (Ref. 86935). A dwarf species with an edentate palate (Ref. 57128).
胸鰭棘對 5個鋸齒有三個。 (參考文獻 51287) 主要尾鰭鰭條的數字: 8+7; 前流尾鰭鰭條的數字: 11-13/11-13.(參考文獻 51287) 肋骨的數字: 6, 在脊椎骨 6 上的第一對.(參考文獻 51287) 神經而血液的棘傾向單一而細長的.(參考文獻 51287) 肩帶短的肱骨突起, 沒有小齒狀突起.(參考文獻 51287) 沒有寬的黑色頸圈在頭部正後方。 (參考文獻 51287)
