IMIS

The list is based on an unpublished list, compiled by E. Karlsbakk, based on literature search and the Aquatic Sciences and Fisheries Abstracts. Almost exclusively original species descriptions have been used as the basis for species information. The preliminary list was then checked against other lists or sources: Gurley (1894), Thélohan (1895), Labbé (1899), Auerbach (1910), Kudo (1920), Shulman (1962), Shulman (1966), Naidenova et al. (1975), Donetz and Shulman (1984), Lom and Dyková (1992) and others. A total of 213 species are listed as valid, in addition, some important synonyms are included. It is likely that the actual number of species is much higher, since many fish species have never been examined. Also, many old myxozoan species described from several unrelated hosts will likely turn out to be complexes of sibling species (e.g. Myxidium oviforme).

The classification used is based on Lom and Dyková (1992). However, it differs in that; (a) the recent genus Polysporoplasma Sitjá-Bobadilla & Alvarez-Pellitero, 1995 is placed in family Sphaerosporidae and seems closely related to Sphaerospora Thélohan, 1892, (b) Genus Paramyxoproteus Wierzbicka, 1986 is considered as a synonym of Schulmania Kovaleva, Zubchenko & Krasin, 1983, (c) P. reinhardtii Wierzbicka, 1986 is a synonym of S. quadriolobata Kovaleva, Zubchenko & Krasin, 1983. The valid binomen for Sphaerospora caudata Parisi, 1910 is considered to be Hoferellus caudatus (Parisi, 1910) (large polysporic plasmodia, spore shape, posterior filaments).

Hosts are listed as valid genus or family of type host, and then other families or simply “other fishes” when the hosts are many and unrelated. When type hosts were not designated in the original description, the first listed is considered the type-host. Only the geographic distribution in the ERMS area is considered. However, several of the myxozoan species in the area are recorded also from, for instance, Australia and New Zealand.Abbreviations used at web site: GB, gall bladder; UB, urinary bladder; NE, northeast; NW, northwest; N, north and so on.
