The Rokel River (RR) basin is one of the most neglected ichthyofaunal basins, despite potential for undetected diversity and high levels endemism. Data on molecular phylogeny freshwater fish from this river are rare. Morphological features alone inadequate precise species identification. Here, a phylogenetic analysis performed based mtDNA Cytb gene eleven cyprinid RR recovered distinct lineages...
