ABSTRACT A new procatopodid, assigned to the genus Poropanchax, is described from a wetland habitat located adjacent to the Inga Falls in Lower Congo. Poropanchax pepo, new species, is distinguished from all congeners by a combination of characters including a higher D/A ratio, rounded anal and dorsal fins, a humeral blotch in males, and the absence of a sharp ventral process on the basipterygium. The finding of a Poropanchax species in Lower Congo was unexpected, since the closest known congeneric population is located in northwestern Gabon, some 700 kilometers to the north. As recognized herein the genus Poropanchax is a clade comprised of five species geographically restricted to humid coastal regions of west and west-central Africa.

来自刚果民主共和国中央省的一个意外的新 Poropanchax（Cyprinodontiformes，Procatopodidae）

摘要 描述了一种新的原足类动物，属于 Poropanchax 属，来自位于下刚果英加瀑布附近的湿地栖息地。Poropanchax pepo 是新物种，与所有同类的区别在于以下特征的组合：更高的 D/A 比、圆形的臀鳍和背鳍、雄性的肱骨斑点以及在 basipterygium 上没有尖锐的腹突。在下刚果发现 Poropanchax 物种是出乎意料的，因为最近的已知同类种群位于加蓬西北部，距北约 700 公里。正如本文所承认的，Poropanchax 属是一个由五个物种组成的进化枝，在地理上仅限于非洲西部和中西部潮湿的沿海地区。
