Sarcocysts were found during the examination of muscle samples from four different Equidae from the zoo in Berlin-Friedrichsfelde (Przewalski’s feral horse, Chapman’s plain zebra, kulan, kiang), a Damara plain zebra from the Cologne zoo, and a domestic horse from Mongolia. Light and electron microscopic features of these sarcocysts correspond largely. The cyst walls of all the six forms represent type 11 from the classification system by Dubey et al. 1989. On this ultrastructural basis, one could postulate the existence of two or only one species, depending on the emphasis that is laid on the presence or absence of large osmiophilic granules within the cyst wall protrusions. Equus caballus przewalskii, E. burchellii chapmani, E. burchellii antiquorum, E. kiang holdereri, and E. onager kulan have not been previously described as hosts for sarcocysts belonging to ТЕМ wall type 11. In addition to the ТЕМ wall type 11 forms, a type 7 form is known in horses. It is not possible for the time being to list Sarcocystis asinus Gadaev, 1978 as a synonym of a Sarcocystis species found in equids. Hence S. asinus is declared a species inquirenda.
