背的软条 (总数) : 13; 臀鳍软条: 8. Diagnosis: last simple dorsal ray ossified and as long as head in largest individuals, ossified at base, ossified portion shorter than head (60-85% of head length); lips poorly developed, without mental lobe; 9 dorsal fin branched rays; scale formula 3.5-4.5/23-26/4.5; 2 scales between lateral line and pelvic-fin base; 12 scales around caudal peduncle; 1-3/10-11 gill rakers on first gill arch (Ref. 2940, 81282).
没有下巴叶的唇一点点发展的。 最后的背部单一的鳍条是大约与在较大的个体中的头部一样长, 这在基底被钙化与短于头部.(大约 60-86% 头长) 背鳍的外部边缘些微地凹曲。 在第一鳃弓上的鳃耙。 浅灰色的, 些微地被上色的侧边有鳞片那一个橘黄色又白色的腹面, 鳍粉红色-淡黄色的除了背部的是深灰色。 尾部的边缘黑色的。 背部的: 4 单一的,9个分枝。 肛门的: 3 单一的,5 鳃的。
Maximum TL was recorded at 20.5 cm (Ref. 2801). Affinities: sympatric with B. bynni occidentalis in Bafing and Upper Niger where they are easily distinguished by the # of scales or absence of the chin lobe. Compared to B. sacratus, B. petitjeani has less scales above the lateral line and a bit longer last simple dorsal-fin ray.
最大体长TL记录为 20.5 公分。 (参考文献 2801) 分类相关: 与在 Bafing 与尼日尔河上游的 B. bynni occidentalis 重叠分布在哪里它们容易地被藉着鳞片数目或没有颏叶区别。
