背棘 (總數) : 0; 背的軟條 (總數) : 14; 臀棘: 0; 臀鰭軟條: 8; 脊椎骨: 39 - 40. The body is relatively deep, the head short and the snout bluntly rounded(Ref. 32347). Two pairs of short barbels are present (Ref. 32347). Small, offwhite tubercles are distributed over the sides of the snout (Ref. 32347). The mouth is wide and ventral; the lower jaw is short, its anterior edge gently curved and covered with a sharp-edged horny sheath (Ref. 32347). Dorsal fin has 4 unbranched and 10 branched rays, anal fin has 3 unbranched and 5 branched rays (Ref. 32347). Alcohol preserved specimens are dark grey-brown dorsally, silver-grey laterally and pale grey ventrally, the fins are pale grey (Ref. 32347). In life, the fishes were intensely silver, darkening dorsally (Ref. 32347).
身體是相當深的,頭部短與吻部鈍地圓的。 (參考文獻 32347) 兩對的短觸鬚出現。 (參考文獻 32347) 小的, offwhite 小瘤被佈滿吻部的側邊.(參考文獻 32347) 嘴巴是寬與腹的; 下面的頜是短, 它的前緣逐漸地彎曲了而且覆蓋著一個邊緣銳利的角鞘。 (參考文獻 32347) 背鰭有 4 不分枝的與 10個分支條, 臀鰭有 3 不分枝的與 5個分支條.(參考文獻 32347) 酒保存的標本是深灰褐色背面, 銀灰色側面地與白灰色腹地，鰭是白灰色.(參考文獻 32347) 活著時，此魚密集銀色, 顏色較深背面。 (參考文獻 32347)
This species can be found in the Juba River, a permanently flowing river through acacia woodland; the fish were caught in a shallow stretch where the water flows rapidly over shingle (Ref. 32347).
這種被發現於在 Juba 河中, 經過洋槐森林地的一條永久流動的河; 魚於水快速地在大砂礫之上流動的水淺的伸展捕獲。 (參考文獻 32347)
