Isospora leptopogoni n. sp. (Apicomplexa: Eimeriidae) from the sepia-capped flycatcher Leptopogon amaurocephalus Tschudi, 1846 (Passeriformes: Rhynchocyclidae) in South America.

Coccidian protozoan species recorded from flycatchers are few, but they have been described with a certain frequency in recent years. In this context, the present study describes a new Isospora sp. from sepia-capped flycatchers Leptopogon amaurocephalus Tschudi, 1846 captured in the Itatiaia National Park and in a reforestation area which is about 60 km away from the park boundaries, in addition to providing a molecular identification via sequencing of the mitochondrial cytochrome c oxidase subunit 1 gene.

Coccidia of Columbiformes: a taxonomic review of its Eimeriidae species and Eimeria columbinae n. sp. from Columbina talpacoti (Temminck, 1809) from Brazil.

Coccidia (Chromista: Miozoa: Eimeriidae) of columbiform birds (Aves: Columbiformes) have been described since the end of the nineteenth century; however, some of these descriptions were poorly detailed or inconclusive. In this sense, the current work makes a detailed taxonomic revision reconsidering and organizing 18 Eimeria spp. and two Isospora spp.

Isospora borbai n. sp. (Chromista: Apicomplexa: Eimeriidae) from gnateaters Conopophaga spp. (Passeriformes: Tyranni: Conopophagidae) in South America.

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.
