SYNOPSIS. Four new species of Eimeria were found in a survey of 255 rats of 14 species in Malaysia. E. tikusi n. sp. and E. edwardsi n. sp. are described from Edwards' rat Rattus edwardsi. The ellipsoidal, single‐layered oocysts of E. tikusi average 30.3 by 24.4 μ. A micropyle is absent; a polar granule is present. Ovoid sporocysts average 14.2 by 9.8 μ. A sporocyst residuum and Stieda body are present. The ovoid, 2‐layered oocysts of E. edwardsi average 29.1 by 21.8 μ. A micropyle is present; a polar granule is absent. Ellipsoidal to ovoid sporocysts average 14.5 by 6.5 μ. A sporocyst residuum is present; Stieda body is small or absent. E. surifer n. sp. is described from the red spiny rat Rattus surifer. Its ellipsoidal 3‐layered oocysts average 34.7 by 24.8 μ. A micropyle is absent; a polar granule is present. The ellipsoidal sporocysts average 15.4 by 9.5 μ. A sporocyst residuum, Stieda body and sub‐Stieda body are present. E. sabani n. sp. is described from the long‐tailed giant rat R. sabanus. Its ellipsoidal 2‐layered oocysts average 28.5 by 21.7 μ. A micropyle is absent; a polar granule is present. The ellipsoidal‐to‐ovoid sporocysts average 11.9 by 8.0 μ. A sporocyst residuum and Stieda body are present.
