Abstract

We document morphological descriptions for 3 newly described Eimeria spp. that infect springbok (Antidorcas marsupialis). Eimeria antidorcasi n. sp. oocysts are ovoid, with average size (n = 346) 26.2 × 18.8 (19.2–33.5 × 13.1–26.5) μm, a length/width ratio of 1.4 (1.2–2.0), a micropyle, and a polar granule sometimes present. Sporocysts are ovoid (n = 336), 11.3 × 7.3 (6.0–14.6 × 5.2–9.8) μm, with a length/width ratio of 1.5 (1.1–2.0), a Stieda body, a prominent, ovoid sporocyst residuum, and one refractile body per sporozoite. Eimeria versfeldi n. sp. oocysts are ellipsoid (n = 136), 38.9 × 26.6 (27.8–48.2 × 21.2–31.0) μm, with a length/width ratio of 1.5 (1.2–2.0), a micropyle cap with sub-micropylar material, and 2–4 polar granules. Sporocysts are elongate-ovoid (n = 132), 18.3 × 9.2 (13.2–22.8 × 6.8–11.2) μm, with a length/width ratio of 2.0 (1.3–2.5), a Stieda body, a small sporocyst residuum present, and an evident nucleus and two refractile bodies per sporozoite. Eimeria gasawayi n. sp. oocysts are subspheroid (n = 87), 14.8 × 13.6 (11.5–20.0 × 11.1–18.2) μm, with a length/width ratio of 1.1 (1.0–1.2), and no micropyle. Sporocysts are elongate-ovoid (n = 82), 9.0 × 4.6 (5.5–12.5 × 3.6–6.4) μm, with a length/width ratio of 2.0 (1.3–2.4), a small Stieda body, and an irregularly shaped sporocyst residuum present. These are the first Eimeria spp. described from springbok.
