Abstract
Twenty-four star-nosed moles, Condylura cristata, collected from the northeastern United States (Maine, Massachusetts, Ohio, Vermont) were examined for coccidian oocysts. All of the moles were infected with from 1 to 4 species of coccidia representing 2 eimerian and 3 isosporan spp., but oocysts of only 4 of these species were present in sufficient numbers for detailed study; these are described as new. Sporulated oocysts of ,i>Eimeria condylurae n. sp. were subspheroid, 17.7 x 15.7 (17-23 x 14-21) μm, with sporocysts ellipsoid, 11.7 x 5.6 (11-14 x 5-6) μm; E. condylurae was found in 3 of 24 (12.5%) moles. Sporulated oocysts of Isospora condylurae n. sp. were ellipsoid, 19.4 x 9.3 (17-21 x 8-11) μm, with sporocysts ovoid, 11.7 x 5.8 (11-13 x 5-7) μm; I. condylurae was found in 12 of 24 (50%) moles. Sporulated oocysts of Isospora cristatae n. sp. were ellipsoid, 15.7 x 10.1 (13-18 x 9-13) μm, with sporocysts ovoid, 11.0 x 5.7 (10-12 x 5-7) μm; I. cristatae was found in 19 of 24 (79%) moles. Sporulated oocysts of Isospora lamoillensis n. sp. were ellipsoid, tapering at both ends, 21.6 x 13.0 (19-23 x 11-14) μm, with sporocysts spindle-shaped, 14.9 x 7.7 (14-16 x 7-8) μm; I. lamoillensis was found in 2 of 24 (8%) moles. Although the second eimerian seen was in 7 of the 24 (29%) moles from Massachusetts, Ohio, and Vermont, there were not enough sporulated oocysts to study in detail to warrant a new species description. Including the 4 new species described here, there are now 48 valid eimerian species and 23 valid isosporan species described from insectivore hosts world-wide.
