et al. (1968) reported Cotylophoron cotylophorum and species of the genus Fischoederius. but were not found by us. Thus, altogether eigth species of amphisomes have been recorded in Iran so far. Paramphistomum cervi

, P. gotoi are Palaearctic species with wide distributional areas and Iran is in the most southernly part of their distribution. Cali cophoron papillosum is a species characteristic for the Oriental region and this is the first report on its occurrence outside this region. The rest are either Oriental (P. gracile

, O. orthocoelium

, G

. crumenifer, G. compressus

, Fischoederius sp.

) or Oriental-Ethiopian (C. spatiosus

, G

. explanatum

, C

. cotylophorum, O. scoliocoelium

) or EthiopianPalaearctic (P. microbothrium) elements. Extending from the centre of their origin nowdays Iran is the most western distributional area for the species P. gracile

, C

. papillosum

, O. orthocoelium, G

. compressus and Fischoederius sp. ( although GOHAR (1934) mentioned F. elongatus is an other part of the Mediterranean area (Egypt) but this finding needs further confirmation) and the most eastern area of the species, P. microbothrium. Thus, the amphistome fauna of Iran is strongly influenced by Oriental and to a lesser extent by Ethiopian elements. Species of fresh water snails, belonging to the Bulinid (ARFAA et al. 1973), Lymnaeid (G HA DIR IAN and HOGHOOGHAI, 1973) and Planorbid (Planorbis planorbis, Gyraulus convexiusculus, G. euphraticus, G. intermixtus) groups and the favourable climate of the country preserve the natural circulation of the host-parasite system.

Öt ezek közül új az iráni faunában: Paramphistomum gracile, Gastrothylax compressus, Carmyerius spatiosus

, Cali cophoron papillosum

, Orthocoelium scoliocoelium

. Állatföldrajzi elemzésük szerint két palaearktikus- (Paramphistomum cervi és P. gotoi

), hat orientális- (Calicophoron pa pillosum , Paramphistomum gracile, Orthocoelium orthocoeliu

m, Gastrothylax crumenifer

, G. com pressus és Fischoederius sp.

), négy orientális-ethiopiai- (Carmyerius spatiosus, Gigantocotyle ex planatum , Cotylophoron cotylophorum

, Orthocoelium scoliocoelium

) és egy ethiopiai-palaearktikus-faj (Paramphistomum microbothrium) fordul elő az iráni kérődzőkben. REFERENCES ARFAA, F. (1962): A study on Paramphistomum microbothrium in Khuzistan S.W.
