In the current study, a new coccidian species (Protozoa: Apicomplexa: Eimeriidae), collected from the rufous-browed peppershrike Cyclarhis gujanensis Gmelin, 1789, is reported from Brazil. Isospora pitiguari n. sp. has oocysts, which are spherical to sub-spherical, 26.8 × 25.7 μm, with smooth, bilayered wall ~1.5 μm thick. Micropyle, oocyst residuum, and polar granule are absent. Sporocysts are...

In this study, the parasites of Pyllotreta atra (Coleoptera: Chrysomelidae) in Trabzon were investigated. Samples of P. atra were collected in different localities of Trabzon. Three different types of parasites from P. atra observed are as follows: Gre-garine (Apicomplexa), Nematode (Tylenchida: Allantonematidae) and larvae of certain parasitoids. The most abundant infection found in this study...

Protozoa of the genus Sarcocystis (phylum Apicomplexa, family Sarcocystidae) is one of the most common parasites affecting animals. Interspecies diagnostic of Sarcocystis genus was based on electron microscopy for many years. Because of absence of visible differences between species with reachable magnifications, light microscopy is useless. In many cases serological diagnostic method have lack...

Current practice in gregarine (Apicomplexa: Eugregarinorida) taxonomy does not include a standard nomenclature and metric set for plane shapes even though most taxonomic works within the group depend on shapebased descriptions. The lack of a uniform shape nomenclature and metric set has produced considerable confusion in gregarine systematics: descriptions of species often are not directly comp...
