A new species of Gyrodactylus (Monogenea, Gyrodactylidae), an ectoparasite from the endemic Iranocichla hormuzensis (Teleostei, Cichlidae), the only Iranian cichlid

摘要: Iranocichla hormuzensis occupies a biogeographically peculiar position. This endemic of southern Iran is the only Iranian cichlid. While it phylogenetically related to African oreochromine members cichlid family, remains unclear how has dispersed into its current range. It one many lasting enigmas biogeography. Monogenean fish parasites may provide useful additional information in such cases. Therefore, I. was examined for these flatworms. A gyrodactylid parasite reported and compared congeners from Palearctic cichlids. In this way, we verify whether shows affinities fishes that are either or close . The species new science described as Gyrodactylus jalalii sp. nov. first description infecting Because fixation method age material, DNA could not be isolated. Due lack genetic data, no conclusions can drawn on phylogenetic positioning. Indeed, phylogeny cannot inferred morphological characteristics alone. Moreover, phenotypically reminiscent belong clade which highly diverse geographic range host choice. Hence, there evidence linking an exclusively cichlid-bound lineage.
