Abstract

Sixteen hairy-tailed moles, Parascalops breweri, collected from the northeastern U.S.A. were examined for coccidian oocysts; all were infected with multiple species of coccidia and 3 genera were represented. Two cyclosporans, 2 eimerians, and 2 isosporans are described as new species. Sporulated oocysts of Cyclospora ashtabulensis n. sp. are subspheroid to ellipsoid, 18 x 14 (14-23 x 11-19) μm, and sporocysts are ovoid, 12 x 7 (8-14 x 5-9) μm; C. ashtabulensis was found in 7 of 16 (44%) moles. Sporulated oocysts of Cyclospora parascalopi n. sp. are spheroid, 17 x 14 (13-20 x 11-20) μm, and sporocysts are ovoid, 11 x 7 (8-14 x 5-8) um; C. parascalopi was found in 8 of 16 (50%) moles. Sporulated oocysts of Eimeria aethiospora n. sp. are subspheroid to ellipsoid, 19 x 13 (15-24 x 10-16) μm, and sporocysts are ovoid, 11 x 6 (8-13 x 4-7) μm; E. aethiospora was found in 4 of 16 (25%) moles. Sporulated oocysts of Eimeria titthus n. sp. are subspheroid, 16 x 14 (13-19 x 11-17) μm, and sporocysts are ellipsoid, 11 x 6 (9-13 x 4-7) μm; E. titthus was found in 4 of 16 (25%) moles. Sporulated oocysts of Isospora ashtabulensis n. sp. are ellipsoid, 20 x 14 (16-24 x 10-18) μm, and sporocysts are ovoid, 10 x 7 (7-14 x 5-10) μm; I. ashtabulensis was found in 5 of 16 (31%) moles. Sporulated oocysts of Isospora parascalopi n. sp. are subspheroid, 15 x 13 (12-17 x 11-15) μm, and sporocysts are ovoid, 9 x 6 (7-13 x 5-8) μm; I. parascalopi was found in 12 of 16 (75%) moles. In addition to these 6 new species, sporulated oocysts of another cyclosporan, another eimerian, and another isosporan were seen, but the number of sporulated oocysts was insufficient for adequate study. The number of coccidians now described from insectivores is 72: 5 cyclosporans, 47 eimerians, and 20 isosporans.
