This paper is devoted to a critical analysis and revision of the systematics of the trematode genus Opisthorchis. It is shown that there is no justification for the recognition of the genera Amphimerus Barker, 1911, Notaulus Skrjabin, 1913, Gomtia Thapar, 1930, Evranorchis Skrjabin, 1944 and Euamphimerus Yamaguti, 1941.
The generic diagnosis of the genus Opisthorchis has been amplified, and on the basis of the information available in the literature mainly, certain species in this genus are suggested to be synonyms of earlier recorded forms. A list is presented of the species recognized and the host or hosts are indicated as far as is possible.
Opisthorchis geminus is recorded from two new hosts, Plectropterus gambensis and Dendrocygna viduata.
