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