Specimen identification in the absence of diagnostic morphological characters (e.g., larvae) can be problematic even for experts. The goal of the present study was to assess the performance of  COI  in discriminating specimens of the fish family   Cyprinidae   in Africa, and to explore whether  COI -phylogeny can be reliably used for phylogenetic comparative analysis. The main objective was to analyse a matrix of  COI  sequences for 315 specimens from 15 genera of African   Cyprinidae   using various distance-based identification methods alongside multiple tests of DNA barcode efficacy (barcode gap, species monophyly on  NJ  tree). Some morphological and biological characters were also mapped on a  COI -phylogeny reconstructed using Maximum Parsimony. First, the results indicated the existence of barcode gaps, a discriminatory power of  COI  ranging from 79 % to 92 %, and that most nodes form well-supported monophyletic clades on an  NJ  tree. Second, it was found that some morphological and biological characters are clustered on the  COI -phylogeny, and this indicates the reliability of these characters for taxonomic discrimination within the family. Put together, our results provide not only an additional support for the  COI  as a good barcode marker for the African   Cyprinidae   but it also indicate the utility of  COI -based phylogenies for a wide spectrum of ecological questions related to African   Cyprinidae  .

Re-evaluation of the discriminatory power of DNA barcoding on some specimens of African Cyprinidae (subfamilies Cyprininae and Danioninae )
