Abstract  Coprological examination of nine African helmeted turtles Pelomedusa subrufa from Kenya revealed the presence of a new coccidium belonging to Eimeria Schneider, 1875. Oöcysts of Eimeria lokuma n. sp. are spherical to sub-spherical, 13.6 (13–14.5) × 13 (12–14) $$\upmu$$m, lack a micropyle and a polar granule, but possess a granular oöcyst residuum. The sporocysts are elongate, oval to spindle-shaped and 8.3 (7.5–9.5) × 4.4 (4–5) $$\upmu$$m. The Stieda body is relatively low, flat and wide, and covered with a membranous, highly flexible, scarf-like structure which protrudes from its strengthened margins. The sporozoites possess two refractile bodies. Based on the presence of a Stieda body, the described species is classified as Eimeria (sensu stricto). [ABSTRACT FROM AUTHOR]

Coprological examination of nine bush vipers Atheris chlorechis imported from Ghana revealed the presence of a new coccidian species belonging to Eimeria Schneider, 1875. Thin walled oöcysts of Eimeria atheridis n. sp. are spherical to slightly subspherical, 22.8 (19–26) × 22.5 (19–25) μm, without micropyle, polar granule and oöcyst residuum. Sporocysts are elongately ellipsoidal, 17.1 (15–19) × 7.5 (6–8) μm, with a dome like, relatively flat Stieda body. Sporozoites possess two refractile bodies and distinct transversal striation. Based on the presence of a Stieda body the species described herein clearly belongs to the Eimeria (sensu stricto). [ABSTRACT FROM AUTHOR]
