A Review of Some Species of Myxidium Bütschli, 1882 (Myxozosporea) From Eels (Anguilla Spp.)

SYNOPSIS. Myxidium spores from various eel hosts ( Anguilla spp.) are compared. Myxidium anguillae, M. enchelypterygii, M. illinoisense, M. serum , and M. zealandicum are synonymized with M. giardi , a ubiquitous species reported from A. anguilla, A. rostrata, A. mossambica, A. japonica, A. reinhardtii, A. bicolor pacifica, A. australis , and A. dieffenbachii. Myxidium uchiyamae, M. lentiforme, M. matsuii and M. acinum are retained, and 2 new species described. Species other than M. giardi appear to be restricted to the Indo-Pacific region.
