We collected faecal samples from 24 dusky rice rats, Melanomys caliginosus (Tomes) (Rodentia: Cricetidae: Sigmodontinae), in a Biological Reserve in Costa Rica, and found three (12.5%) to be infected with a species of Eimeria Schneider, 1875, which we describe here as new. Sporulated oöcysts of Eimeria caliginosa n. sp. are almost spheroidal and measure 16–21 × 17–20 (mean 19.6 × 18.2) μm; micropyle, oöcyst residuum and polar granule are absent. Sporocysts are ovoidal, 9–13 × 6–8 (mean 11.2 × 6… Expand
