Abstract

A new isosporoid coccidian (Apicomplexa, Eimeriidae) species from the grey-hooded flycatcher, Mionectes rufiventris, from Brazil, is reported in the current study. Isospora mionectesi sp. nov. oocysts are ellipsoidal, 28.3 × 21.2 μm, with smooth, bilayered wall, ~1.3 μm. Micropyle and oocyst residuum are absent, but one or two polar granules are present. Sporocysts are elongate ellipsoidal, 19.7 × 11.7 μm. Stieda body rounded and substieda body prominent. Sporocyst residuum is subspherical and compact. Sporozoites are vermiform with one refractile body and a nucleus. © 2009 2009 W. Stefański Institute of Parasitology, PAS.
