Eimeria strangfordensis sp. n., Eimeria barleyi sp. n., and eimeria antonellii sp. n. from the eastern woodrat (Neotoma floridana) from Pennsylvania.

Three new eimerian species are described from the eastern woodrat, Neotoma floridana, in Pennsylvania. Sporulated oocysts of Eimeria strangfordensis sp. n. are broadly ellipsoidal, 25.0 to 31.7 (29.1) x 20.5 to 26.2 (24.1) with subspherical to ovoid sporocysts, 10.6 to 17.2 (13.4) x 7.4 to 16.4 (10.9). Oocyst wall is thick, rough, pitted, and two layered with no micropyle. Oocyst and sporocyst residuum and Stieda body are present; polar granule is absent. Sporulated oocysts of Eimeria barleyi sp. n. are broadly ellipsoidal, 18.0 to 24.8 (21.7) x 16.2 to 21.2 (18.4) with ovoid sporocysts, 9.8 to 11.9 (10.7) x 7.4 to 8.7 (8.0). Oocyst wall is rough, pitted, and two layered with micropyle. Polar granule, Stieda and substiedal bodies, and sporocyst residuum are present; oocyst residuum is absent. Sporulated oocysts of Eimeria antonellii sp. n. are spherical to ellipsoidal, 14.8 to 23.8 (18.2) x 11.9 to 20.5 (14.8) with ovoid sporocysts, 7.4 to 9.8 (8.5) x 4.5 to 6.6 (5.6). Oocyst wall is smooth, and single layered with no micropyle. Polar granule, oocyst and sporocyst residuum, and Stieda body are present.
