A new species of Eimeria Schneider, 1875 from a cracid bird, Mitu tuberosum Spix, held in captivity is described from Brazil. Oöcysts of Eimeria abmitu n. sp. are ovoid, with a smooth, colourless, bilayered wall, measure 24.2 × 15.5 μm and have a length/width ratio of 1.56. The sporulated oöcysts contain two to five polar granules and four ellipsoidal sporocysts measuring 13.6 × 6.4 μm, each with a small crescent-shaped Stieda body, a sub-Stieda body, a loosely granular sporocyst residuum and two comma-shaped sporozoites each with a spherical refractile body.
