ResumoFaecal examination of the long nosed vine snake Ahaetulla nasuta Lacepede, 1789 revealed two species of caryosporan coccidia. The morphology of one species fits well with a description of Caryospora ahaetullae Modrý et Koudela, 1994, the second is a previously undescribed species. Oocysts of Caryospora veselyi sp. n. were spherical, 18.9 (16.5-21.5) µm in diameter, with pitted and brownish oocyst wall about 1.5 µm thick. An irregular polar granule about 2.0 × 1.0 µm was observed in 35% of the oocysts examined. Sporocysts were octozoic, ovoidal to ellipsoidal, 13.7 (13.0-15.5) × 10.3 (9.0-11.0) µm with a shape index 1.3 (1.2-1.4). Stieda and substieda bodies were present. Sporocyst residuum was present as small granules of irregular size scattered among sporozoites. Both species sporulated within 72 hours. The infected snake did not show clinical signs of disease.
