dc.descriptionFor many decades, Nannocharax luapulae has been considered to be widespread in the southern part of the Upper Congo basin. However, meristic, morphometric and COI barcoding evidence revealed that its geographical distribution is restricted to the Luapula-Moero basin. The populations of the Upper Lualaba are assigned to a new species, N. chochamandai. This new species, though highly similar to N. luapulae, can readily be distinguished from it by its lower number of lateral line scales, 41-46 (vs. 49-55), its pectoral fin reaching the pelvic-fin insertion (vs. not reaching the pelvic-fin insertion) and its pelvic fin reaching the base of the anal fin (vs. not reaching the base of the anal fin). Specimens of N. chochamandai display thickened pads on the first three pelvic-fin rays that exhibit intraspecific variation in development, which appears to be related to the flow-strength of the river in which these Nannocharax specimens occur. Nannocharax luapulae is redescribed and an updated identification key to the Nannocharax species of the Congo basin sensu lato is provided as well. Some fish conservation issues related to N. luapulae and N. chochamandai are also highlighted. This article is protected by copyright. All rights reserved.
