TL;DR: Three species in the group of “small” Barbus from West Africa were analyzed by enzyme elcctrophoresis to assess their genetic differentiation and revealed two sets of species, i.e. diploid and tetraploid.

TL;DR: Tetraploidi- zation must have occurred long ago in large African Barbus, and may correspond to the same event responsible for the origin of the European species.

TL;DR: Results suggest that the 59 and 45 kDa components are not additional subunits of an oligomeric protein but results from cleavage of the 86 kDa polypeptide.

TL;DR: A phylogenetic hypothesis is proposed for the large west’african Barbus based upon the presence of certain branchial parasites, and the variability of meristic and morphological characters of B. Sacratus and B. petitjeani was also sfudied.
Abstract: THE LARGE BARBUS (TELEOSTEI, CYPRINIDAE) OF WEST AFRICA : TAXONOWC STUDY AND BRANCHIAL PARASITOFAUN4 As a result of a revision of ihe large wesf african Barbus, the species B. waldroni and B. occidentalis belong to the same group as B. bynni and both fortns should be considered as sub-species of fhis group. This stafetnent is confirtned by the study of the branchial Monogenea. The variability of meristic and morphological characters of B. Sacratus and B. petitjeani was also sfudied as well as fheir distribution. B. gruveli and B. lagoensis are only known by ihe type specimens until nom. The species B. wurtzi is considered fo belong to the genus Barbus and net to Varic,orhinus *in which it was previously placed. Based upon the presence of certain branchial parasites, a phylogenetic hypothesis is proposed for the large west’african Barbus. I
