Popis: Eimeria forresteri n.sp. is described from Ramphastos toco (Piciformes: Ramphastidae) and Isospora graculai Bhatia, Chauhan, Arora & Agrawal, 1973 is redescribed from Gracula religiosa (Passeriformes: Sturnidae). E. forresteri oocysts are ellipsoid, 24.5 by 17.8 μm (21.0 to 27.0 by 16.0 to 19.5), and have a trilayered wall about 1.5 μm thick. One to three polar granules are present; micropyle and oocyst residuum are absent. Sporocysts are ellipsoid, 14.8 by 7.3 μm (12.0 to 17.0 by 6.0 to 8.0), with a smooth, thin wall. Stieda and substieda bodies and sporocyst residuum are present. Sporozoites measure 9.2 by 3.4 μm (6.0 to 12.0 by 3.0 to 4.5), with anterior and posterior refractile bodies. I. graculai oocysts are subspherical, 24.6 by 22.4 μm (20.0 to 27.8 by 20.0 to 24.0), and have a single-layered wall about 1.5 μm thick. One or two polar granules are present; micropyle is absent. Oocyst residuum is sometimes present, consisting only of a few indistinct granules. Sporocysts are ovoid, 17.7 by 11.6 μm (15.0 to 20.0 by 10.0 to 13.0), with a thin, smooth wall. Stieda and substieda bodies and sporocyst residuum are present. Sporozoites measure 14.5 by 3.5 μm (12.0 to 16.5 by 3.0 to 3.8), with anterior and posterior refractile bodies. ac]19831122
