| Abstract: | SUMMARY. Dorisiella arizonensis n. sp. (Sporozoa: Eimeriidae) is described from oocysts in the feces of a desert woodrat, Neotoma lepida , from Grand Canyon National Park, Arizona. The oocysts are spherical to subspherical, measure 20.8–21.8 × 20.8–22.9 μ, with a mean of 21.0 × 21.8 μ, and have a two-layered wall. They contain 1 to 3 refractile granules but no residual body. The two lemon-shaped sporocysts have a Stieda body, 8 sporozoites, and a few to many scattered, round, clear residual granules or bodies. |
