背的软条 (总数) : 13 - 16; 臀鳍软条: 8. Diagnosis: last simple ray partly ossified at base (no strong spine) and distinctly longer than head; lower reduced, substituted by horny sheath; 9-12 (usually 10) dorsal fin branched rays; scale formula 3.5-4.5/23-29/3.5-4.5; 2 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle (Ref. 2940, 81282).
大的嘴, 下唇缩小的而且取代了角的鞘。 非常短的触须，前面的一些, 在后部的 7-15% 头长。 在较后面的部分上鳞片有趋集于一点的条纹。 长的背鳍 , 最后的单一鳍条在基底 (等于头长当幼鱼时) 钙化了清楚比较长的头长当成鱼时。 背部的: 4 单一的,9-12个分枝。 肛门的: 3 单一的,5个分枝。
Barbus wurtzi has differences in meristic and morphometric characteristics depending on which population; body depth varies between 26-33% in Guinean rivers and 34-43% in the Cavally and Nipoué rivers; the caudal peduncle length-height ratio is approximately 100% in Cavally-Nipoue and reaches an average of 140% in Guinean rivers; population east of Ivory Coast has intermediary characteristics such as number of scales above and below the lateral line: 4.5 in Guinea and Ivory Coast, 3.5 in western part of Ivory Coast and east of Liberia (Ref. 2940). Maximum TL was recorded at 27.5 cm (Ref. 2801).
体节形质特徵与形态测量特徵的不同根据族群。 体高在几内亚地区的 26-33% 之间改变而且改变卡瓦利与 Nipoue 的 34-43% 。 在卡瓦利中的每长度比 100% 尾柄高度-Nipoue& 几内亚地区的大约 140%。 科特迪瓦以东的族群有中间的特性鳞片的例如数字, 在侧线的周围: 4.5 在几内亚与科特迪瓦,3.5 在科特迪瓦利比里亚以东。 最大体长TL记录为 27.5 公分。 (参考文献 2801)
