          Abstract

          Isospora canaria Box, 1975 (Protozoa, Apicomplexa, Eimeriidae) is reported and described from canaries Serinus canaria (Linnaeus) in southeast Brazil. Its oöcysts are subspheroidal to ellipsoidal, 24.4 × 22.2 μm, with smooth, bilayered wall, ~1.2 μm. The micropyle and the oöcyst residuum are absent, but a polar granule is present. The sporocysts are lemon-shaped, 17.6 × 10.6 μm. The Stieda body is nipple-like, and substieda body is prominent and homogeneous. The sporocyst residuum is composed of scattered granules. The sporozoite has anterior and posterior refractile bodies and a nucleus. The report of this coccidium recovered from exotic canaries in South America is relevant to native passerines, mainly to Carduelis yarrellii, which are listed as vulnerable species by IUCN (International Union for Conservation of Nature and Natural Resources).
