Using a combination of morphological and molecular data, we describe a new apicomplexan parasite, Isospora svecica sp. n., from the white-spotted bluethroat, Luscinia svecica cyanecula, from the Czech Republic. Oocysts were found in its intestinal tract. Sporulation was exogenous and took 1-3 days. The oocysts were slightly ellipsoidal, of average size 26.17 × 20.33 μm, with a smooth bilayered wall. Micropyle, oocyst residuum, and polar granules were absent. Sporocysts were bottle-shaped, of an average size of 18.82 × 8.82 μm, with a thin, colourless wall. A conspicuous knob-like Stieda body was present. Substieda body was barely visible. Sporocyst residuum was present in the form of granules of various sizes. Sporozoites were banana-shaped and contained large anterior and small posterior refractile bodies. Partial DNA sequences of three genes were obtained from oocysts of Isospora svecica sp. n., being most closely related to other isosporans described from passerines. Little is known about the parasites of the avian family Muscicapidae, including coccidia, a highly prevalent parasitic protist group in all vertebrate classes. Only six species of the genus Isospora have so far been described in Muscicapidae, together with several "Isospora sp." that in fact most likely represent Isospora lacazei. The newly described Isospora svecica sp. n. differs morphologically from other coccidia reported from muscicapid birds, and represents the first coccidian species described from Luscinia svecica.

Two morphologically similar, but phylogenetically unrelated Eimeria species from ancient mammals, African Tree Pangolin Phataginus tricuspis and Sunda Pangolin Manis javanica (Pholidota: Manidae), from two distant biogeographic realms (Afrotropical and Oriental), are characterized and compared morphologically and molecularly. Phylogenetic analyses produced an unstable topology. However, while precise position of the two Eimeria species from pangolins could not be firmly established due to the lack of related taxa, it is evident that they are not closely related and do not fall into any of the so far recognized eimerian lineages. Moreover, an eimerian found in P. tricuspis is described as a new species Eimeria nkaka n. sp., based on morphology of oocysts, endogenous developmental stages and sequence data.

One of three (33%) captive specimens of Oustalet's chameleon, Furcifer oustaleti (Mocquard) originally from Madagascar and housed at the Oklahoma City Zoological Park Herpetarium, Oklahoma County, Oklahoma, USA, was found to be passing an undescribed species of Choleoeimeria in its faeces. Oocysts of Choleoeimeria fischeri sp. n. were cylindroidal, 30.3 × 16.8 (28–34 × 15–18) µm, with a smooth, bilayered wall and a length/width ratio (L/W) of 1.8. A micropyle and oocyst residuum was absent but a fragmented polar granule was often present. Sporocysts were ovoidal, 9.6 × 8.0 (9–10 × 7–9) µm, with an L/W of 1.2. Stieda, sub-Stieda, and para-Stieda bodies were absent. The sporocyst residuum consists of large globules dispersed between sporozoites. Sporozoites were elongate, 8.6 × 2.9 (8–10 × 2–3) µm, with an elongate posterior refractile body. The new species represents the second coccidian described from this lizard.

Eimeria dorcadis Mantovani, 1966 is redescribed from dorcas gazelle (Gazella dorcas (L.)) from Saudi Arabia. Oocysts were detected in 7 out of 22 faecal samples (32%) using floatation method. The sporulated oocysts are cylindrical, slightly flattened at the micropylar pole, measure in average 32 × 19 μm (27–36 × 16–24 μm), length/width ratio being 1.7 (1.5–2.1). Oocyst wall is 1.2 μm thick, smooth, double-layered; outer layer is slightly thicker, light blue in colour; inner layer brownish, with micropyle in the inner layer and apparently continual outer one, measures 2.2 μm, but lacks a micropylar cap. The sporocyst elongateellipsoidal, measures 14 × 8 μm (12–17 × 6–9 μm), length/width ratio being 1.8, with sporocyst residuum as circular compact, coarse, refractile granules. Stieda body is present, while substieda body is absent. Sporozoites banana-shaped, measure 11 × 2.5 μm, each with a large spheroidal refractile body at the wider pole. Sporulation time is 2–3 days at 25 ± 2 °C.
