Genetic relationships among 24 Italian and Adriatic populations of barbs were assessed using electrophoretic analysis of allozymes and mitochondrial DNA sequences of the cytochrome b gene.Results obtained with both markers were concordant, but they were not congruent with the current morphology-based systematics and taxonomy. Populations assigned to the same nominal taxa (B.caninus, B.petenyi and B.rebeli), were very divergent in both allozymes and mtDNA,indicating that these populations deserve recognition as different units for conservation and management.On the other hand, the two fluvio-lacustrine taxa considered as distinct species are genetically very close to each other, showing no clear differences at either allozymes or mtDNA. The population of B. caninus from Pellice River carried allozyme alleles and mtDNA specific for B. plebejus, indicating a genetic introgression towards the former species.
