Mjukstrålar i ryggfenan (totalt) : 13 - 16; Mjukstrålar i analfenan: 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).
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).
