“…In contrast, this standard approach related to taxonomic groups of hosts is incompatible with the presence of the genotypes of I. sporophilae in this monophyletic group; since this coccidian is a parasite of buffy-fronted seedeaters Sporophila frontalis (Verreaux, 1869) and uniform finches Haplospiza unicolor Cabanis, 1851, which are passerines of the family Thraupidae and suborder Passeri. Thus, this phylogenetic analysis maintains the assumption raised in Rodrigues et al [17] that this monophyletic group is related with coccidia of neotropical birds, and not necessarily related to taxonomic groups of hosts.…”

Background The gnateaters Conopophaga spp. are insectivorous passerines commonly observed in high and humid forests, where they remain lodged in thin branches and, sometimes, they fly to the ground to catch insects. The insectivorous feeding habit is related to low prevalence and density of coccidians in passerines; however, several coccidian species are recorded for families of insectivorous passerines. Purpose This study aimed to examine the feces from gnateaters Conopophaga spp. captured in the municipality of Barra Mansa and in the Itatiaia National Park, State of Rio de Janeiro, Southeastern Brazil, to determine what coccidian parasites were present. Methods Nine gnateaters were captured with mist nets. Coccidian oocysts were recovered from the fecal samples by flotation in Sheather's saturated solution. Morphological observations, line drawings, photomicrographs and measurements were made in optical microscopy and digitally edited. The molecular analysis included the study of the sequence of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene, with phylogenetic reconstructions based on the neighbor-joining and maximum likelihood analysis. Results Four Conopophaga spp. were positive for oocysts. An Isospora sp. considered as new to science is described and identified from Conopophaga melanops (Vieillot, 1818) and Conopophaga lineata (Wied, 1831). Isospora borbai n. sp. has oocysts that are subspheroidal, 17-22 × 15-22 (20.2 × 19.1) µm, with rough, bilayered wall, c.1.7 μm thick. Micropyle present, but without micropyle cap. Oocyst residuum absent, but one or two polar granules are present. Sporocysts are ellipsoidal, 12-15 × 8-11 (14.1 × 9.1) µm. The Stieda body is knob-like to half-moon-shaped and sub-Stieda body is rounded. Sporocyst residuum is present, composed of scattered spherules of different sizes. Sporozoites are vermiform with refractile body and nucleus. Molecular analysis at the cox1 gene exhibited similarity greater than 99% with Isospora spp. isolates from other Neotropical passerine birds. Conclusion Based on the morphological and molecular features, I. borbai is considered as new to science and the first coccidian species recorded from Conopophagidae.

“…Eimeria tenella (Railliet, Lucet, 1891) was used as the outgroup. Isospora borbai sat in a clade with the highest similarity of 99.0-99.5% with Isospora lopesi Silva-Carvalho et Berto, 2018 [15], Isospora sagittulae McQuistion et Capparella, 1992 [16] and Isospora sporophilae Carvalho-Filho, Meireles, Ribeiro et Lopes, 2005 [17] (Fig. 3).…”

“…The phylogenetic proximity of this coccidian species to the pseudoparasite isolate from the bank voles in Czech Republic weakens the theory of the formation of a monophyletic group with Isospora spp. from Neotropical passerines (Rodrigues et al 2019, Trefancová et al 2019.…”

Isospora sepetibensis Berto, Flausino, Luz, Ferreira and Lopes, 2008 is a protozoan coccidian parasite (Chromista: Miozoa: Coccidiomorphea: Coccidia) that was originally described from Brazilian tanagers Ramphocelus bresilius (Linnaeus, 1766) in the Marambaia Island in the Coast of the State of Rio de Janeiro. In the current work, this species was identified from black-goggled tanagers Trichothraupis melanops (Vieillot, 1818) in the Itatiaia National Park, which is a protected area with a high degree of vulnerability in the interior of the State of Rio de Janeiro, distant in more than 100 km of the type-locality. Its oocysts are sub-spherical to elongate ovoidal, 25.9 × 20.7 µm with smooth, bi-layered wall, ~ 1.3 µm and length/width ratio of 1.1-1.4 (1.26). Micropyle and oocyst residuum absent, but one or two polar granules are present. Sporocysts are ellipsoidal, 16.8 × 10.3 µm, with both Stieda and sub-Stieda bodies. Sporocyst residuum present and sporozoites with refractile body and nucleus. Molecular analysis was conducted at the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. This new isolate exhibited similarity greater than 98% with Isospora spp. isolates from other Neotropical passerines and with an Isospora sp. pseudoparasite of voles of Eurasia. This is the first coccidian parasite from a New World tanager to have a molecular identification of the cox1 gene.
