Abstract
A new species of isosporan (Apicomplexa: Eimeriidae) is reported from two magpie jays Calocitta formosa (Swainson) (Passeriformes: Corvidae) from Costa Rica. Oocysts of Isospora calocitta n. sp. are spherical t o subpherical, 28.8 x 27.7 (26.5-31.0 x 25.0-29.5) mu m and have a sha pe index (length/width) of 1.04 (1.00-1.11). A micropyle and oocyst re siduum are absent, but 1-3 polar granules are present. Sporocysts are ovoidal, 20.1 x 12.6 (19.0-21.5 x 11.5-13.5) mu m, and have Stieda and substieda bodies and a shape index of 1.60 (1.47-1.69). A diffuse spo rocyst residuum is present and each sporozoite contains two refractile bodies. A list of Isospora spp. in corvid birds is presented.
