The type material of M. lepomicus Li and Desser, 1985, described from a variety of organs of L. gibbosus, has deteriorated, and spores are not to be found on the slide. The species description includes a schematic drawing of the spore. Until additional samples are obtained the species is considered a species inquirendae. Myxobolus gibbosus Li and Desser, 1985, is a homonym of M. gibbosus Herrick, 1941. Desser (1993) proposed Myxobolus Hi as a nomen novum to replace M. gibbosus Li and Desser, 1985. However, Landsberg and Lom (1991) considered M. gibbosus Li and Desser, 1985, to be a junior synonym of M. uvuliferus, and thus both M. gibbosus and M. Hi become junior synonyms of M. uvuliferus. The report by Hoffman (1998) that M. gibbosus Li and Desser, 1985, is a junior synonym of M. osburni cannot be supported on the basis of spore shape. The 6 confirmed species of Myxobolus mentioned above are known to parasitize L. gibbosus or related centrarchid fishes in North America. Myxobolus magnaspherus and M. paralintoni have been found in redear sunfish (Lepomis microlophus (Giinther, 1859)) in Mississippi, U.S.A. (D. K. Cone, Saint Mary's University, Copyright © 2011, The Helminthological Society of Washington and R. M. Overstreet, Gulf Coast Research Laboratory, unpublished data) and redbreast sunfish (Lepomis auritus (Linnaeus, 1758)) in Maryland, U.S.A. (Hayden and Rogers, 1997), respectively. Myxobolus osburni has been reported (Herrick, 1936; Otto and Jahn, 1943) from bluegill sunfish (Lepomis macrochirus Rafinesque, 1819), smallmouth bass (Micropterus dolomieu Lacepede, 1802), and black crappie (Pomoxis nigromaculatus (Lesueur, 1829)). The genus clearly has undergone a diverse radiation in these hosts, and it is of ecological interest that all 6 species are found in L. gibbosus in Algonquin Park and that all occupy distinct and very specific tissue sites in this host species. Acknowledgments The research was funded by a Natural Sciences and Engineering Research Council of Canada (NSERC) Research Grant awarded to the author. Thanks are extended to the staff of the Harkness Research Laboratory for their help and hospitality and to Sherwin Desser, University of Toronto, for providing constructive comments on a draft of the paper.
