Abstract

A new species of coccidian is reported from the Peruvian red-breasted meadowlark, Sturnella bellicosa (Passeriformes: Icteridae) housed at the National Aquarium in Baltimore, Maryland. Oocysts of Isospora bellicosa Spa n. are ellipsoidal, ovoid, or oblong, 29.4×23.5 (26.4-31.6×21.0-26.4) µn with a shape index (length/width) of 1.25 (1.09-1.41). A micropyle is absent but a polar granule is present; a small oocyst residuum is found in about 1/3 of the oocysts. The sporocysts are ellipsoidal, 17.8×10.7 (16.8-18.6×10.2-11.2) urn, possess Stieda and substieda bodies, and have a shape index of 1.67 (1.52-1.77). The sporocyst residuum is diffuse and consists of numerous small granules. Sporozoites each possess 3 refractile bodies.
