Eimeria Macyi sp. n. (Protozoa: Eimeriidae) from the eastern pipistrelle, Pipistrellus subflavus, from Alabama.
The subspherical to broadly ellipsoidal oocysts of Eimeria macyi measure 16 to 21 by 15 to 19 mu (mean 19.0 by 17.6 mu), and sporocysts measure 10 to 12 by 6 to 8 mu (mean 11.0 by 7.0 mu). The rough walled oocysts lack a micropyle and residuum, but a sporocyst residuum and polar granule are present. This is the first description of coccidian oocysts from the genus Pipistrellus.
