ABSTRACT. Twenty-two Dactylogyrus, one Ancyrocephalus and one Dogelius spp. were found on Iranian natural water fishes in three water systems. Of them, thirteen Dactylogyrus spp. and Ancyrocephalus paradoxus were identified to species and Dogelius mokhayeri sp. n. was described as a new species. All species found are new for the Iranian fauna. Nine Dactylogyrus spp., which all seem to be new, undescribed species and had been collected mostly in the gulf region, were identified to the genus. KEY WORDS: Fish, Monogenea, gill parasites, Iran. The helminth fauna of Iran is poorly studied. There are only few works concerning Trematoda, Cestoda, Nematoda and Acanthocephala infections of Iranian fishes (ESLAMI and ANWAR 1971; ESLAMI et al. 1972; GOLVAN and MOKHAYER 1973; MOKHAYER 1975, 1976). No data are available, however, on Monogenea of Iranian fishes. Iranian freshwaters belong to three different water systems. Waters in Northern Iran belong to the AraloCaspian region, where the parasite fauna of fishes has been intensively studied in the Soviet Union. Several known and new monogeneans have been reported from Azerbaidzhan (MIKHAILOV 1973 1974), Uzbekhistan (OSMANOV 1965) and Daghestan (ALIGADZHIEV et al. 1984). The southernwestern part of Iranian freshwaters belong to the Gulf-River Tiger region, from where Iraqi scientists (ALI et al. 1986, 1987a, 1987b) reported some dactylogyrids. Waters in the Central and Eastern part of Iran run into undrained sodium lakes. This territory might be influenced by the Indian fauna region, the monogenean fauna of which was reviewed by GUSSEV (1973-74). This paper reports monogenean fish parasites from Iranian natural waters and describes a new species under the name Dogelius mokhayeri sp. n.
