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. The oöcysts recovered from P. leucoptera and D. 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.
2015 年，伊索孢子虫（Isospora parnaitatiaiensis）Silva、Rodrigues、Lopes、Berto、Luz、Ferreira 和 Lopes 在巴西东南部的伊塔蒂亚伊国家公园的一个新宿主——平原蚁鸟（Dysithamnus mentalis）和白肩火眼鸟（Pyriglena leucoptera）中被发现，同时还提供了基于线粒体细胞色素 c 氧化酶亚基 1 基因测序的初步基因型特征。从 P. leucoptera 和 D. mentalis 中回收的卵囊具有多态性和基因型差异，但这些差异不足以描述新物种，而只是与每个宿主相关的 I. parnaitatiaiensis 的不同基因型和形态型。这些形态和分子变异与正在进行的物种形成和对各自宿主物种的适应性发展过程有关。
