Abstract: 

The taxonomic status of the Iran blind cave barb, Iranocypris typhlops, is somehow ambiguous and molecular analysis can be helpful in clarifying its taxonomy. Based on the existing hypotheses on the systematic status of the blind cave barb, the 5' sequence of COI was used to analyze its systematic status compared to the species of the genera Barbus, Garra and a number of other cyprinids, especially Cyprinid species of Iran, inhabiting rivers in Zagross Mountains. The sequences reported in this study were among the first molecular sequences for the Iran blind cave barb, the first COI sequence for Garra rufa (in Iran) and were the first reports for the species including Capoeta aculeatae, Capoeta trutta, Barbus lacerta, Kosswigobarbus kosswigi, Kosswigobarbus sublimus, Luciobarbus barbulus, Luciobarbus esocinus and Cyprinion macrostomum. Based on the observations made in the phylogenetic analysis, no close relationship was inferred for the blind cave barb and the genera Barbus, Capoeta, Kosswigobarbus, Luciobarbus and Cyprinion. However, there was a close relationship between the blind cave barb and the species of the genus Garra, especially the native G. rufa. Finally, it might be possible to consider blind Iran cave barb as close relatives of G. rufa, which has experienced the miniaturization phenomenon during its evolution. Among the cave barb specimens analyzed, one discless fish carried a haplotype, formerly reported for the disced form of the blind cave barb. This observation can be inferred as an indication of the possibilities such as hybridization between the two disced and discless forms or the instability of disc bearing feature in the blind cave barbs, for which the clarification is in need of more detailed analysis.
