New species of eimeriid coccidia (Apicomplexa: Eimeriidae) is described from the Common Wood Pigeon Columba palumbus (Aves: Columbidae). Sporulated oocysts of Eimeria columbapalumbi sp. n. are ellipsoidal 24–17 × 18–15 µm. Micropyle and oocyst residuum are absent. Sporocysts are broadly ellipsoidal, 11–16 × 6–7µm, with Stieda body. Substiedal body is absent. Sporocyst residuum is scattered, composed of hundreds of small granules. Sporozoites are elongate and slightly curved, each with two refractile bodies. There are two irregularly shaped polar granules present in the oocyst. The endogenous development takes place within the enterocytes of jejunum.

A new species of isosporoid coccidia (Apicomplexa: Eimeriidae) is described from captive Himalayan Black Bulbul Hypsipetes leucocephalus (Passeriformes: Pycnonotidae). Sporulated oocysts of Isospora annthomassonae n. sp. are subspherical to slightly ellipsoidal 32.0 ± 1.5 × 29.4 ± 1.3 (30–35 × 27–31) μm. Micropyle, oocyst residuum and polar granule are absent. Sporocysts are broadly ellipsoidal, 24.6 ± 1.4 × 12.9 ± 0.7 (22–28 × 12–14) μm, with Stieda and substiedal bodies. Sporocyst residuum is broadly ellipsoidal, 11.3 ± 0.8 × 9.5 ± 0.7 (9–13 × 8–11) μm, composed of hundreds of small granules. Sporozoites are elongate and slightly curved, each with two refractile bodies.

A new species of Isospora Schneider (Apicomplexa: Eimeriidae) is described from captive Blue-crowned Laughingthrush Dryonastes courtoisi (Ménégaux, 1923) (Passeriformes: Timaliidae). Sporulated oocysts of Isospora courtoisii n. sp. are ellipsoidal 24.5 × 14.5 μm. Micropyle and oocyst residuum are absent. Sporocysts are broadly ellipsoidal, 15.9 × 8.5 μm, with Stieda and substieda bodies. Sporocyst residuum is scattered composed of hundreds of small granules. Sporozoites are elongate and slightly curved, each with two refractile bodies. The nuclei of the sporozoites were not well discernible. Considering the critically endangered status of Dryonastes courtoisi and assumed high host specificity of described coccidium, also I. courtoisi can be classified as critically endangered organism.
