Abstract Isospora parnaitatiaiensis Silva, Rodrigues, Lopes, Berto, Luz, Ferreira & Lopes, 2015 was identified from a new host, the plain antvireo Dysithamnus mentalis (Temminck), and also from the white-shouldered fire-eye Pyriglena leucoptera Vieillot, in its type-locality, the Itatiaia National Park in the southeastern Brazil, and a preliminary genotypic characterisation by sequencing the mitochondrial cytochrome c oxidase subunit 1 gene is provided.

mentalis were polymorphic and have genotypic differences that were not considered sufficient for the description of new species, but only different genotypes and morphotypes of I. parnaitatiaiensis related to each host. These morphological and molecular variations were associated with a process of ongoing speciation and in adaptive development to their respective host species.
Introduction Thamnophilidae Swainson is composed of small birds frequently observed capturing ants and other arthropods in dense vegetation. Due to this insectivorous behavior, they are recognised as ‘antbirds’. In South America, two major areas of distribution for this family are the Atlantic Forest and Amazon biomes (Wiens, 1989; Zimmer & Isler, 2003). Passerines can be parasitised by several parasites, both surface, blood or intestinal, the coccidians of Isospora being the most frequently reported. However, until recently the only species of Isospora Schneider, 1881 described from thaminophilid birds was Isospora sagittulae McQuistion & Capparella, 1992, a parasite of the spotted antbird Hylophylax naevioides Lafresnaye in Ecuador. This species wa
