title: Myxobolus mississippiensis n. sp. (Myxosporea) from gills of Lepomis macrochirus in Mississippi.
abstract: Myxobolus mississippiensis n. sp. is described from gill lamellae of the bluegill (Lepomis macrochirus) inhabiting the Pascagoula River System, Mississippi. Fresh spores measure 16.4-18.7 microns long, 3.9-6.2 microns wide, and 4.7-6.2 microns thick. Spore width to length ratio is 1:3.2. Polar capsules are 5.5-7.8 microns long and 1.5-2.3 microns wide, with 9-10 filament coils that when extruded measure 42.1 +/- 4.2 microns. This parasite is unique among known species of Myxobolus in having spores that are lenticular in frontal view.
