Four new coccidia (Apicomplexia: Eimeriidae) from anoles (Lacertilia: Polychrotidae) in the Dominican Republic.

Fecal samples from 25 Anolis armouri, 2 Anolis bahorucoensis, 48 Anolis cybotes, and 21 Anolis olssoni (Lacertilia: Polychrotidae) from southern Hispaniola were examined for coccidian oocysts. Two eimerians and 2 isosporans are herein described as new species. Sporulated oocysts of Eimeria schwartzi n. sp. from A. armouri are ellipsoidal, 22.7 (20.8-25.0) x 15.7 (14.6-17.7) microns, with spherical to subspherical sporocysts, 7.9 (6.2-9.4) x 7.4 (6.2-8.3) microns. Sporulated oocysts of Isospora reui n. sp. from A. bahorucoensis are spherical to subspherical, 18.2 (15.6-20.0) x 17.8 (15.6-19.8) microns, with ovoid sporocysts, 11.9 (10.4-12.7) x 8.5 (7.5-9.4) microns. Sporulated oocysts of Isospora hendersoni n. sp. from A. armouri and A. cybotes are spherical to subspherical, 23.2 (20.8-26.0) x 21.1 (18.4-23.9) microns, with ellipsoidal sporocysts, 14.7 (12.5-15.6) x 10.0 (9.2-11.4) microns. Sporulated oocysts of Eimeria avilae n. sp. from A. olssoni are cylindrical, 29.3 (26.0-33.3) x 15.9 (13.5-18.9) microns, with ellipsoidal sporocysts 10.2 (9.4-11.4) x 6.8 (5.2-8.0) microns.
