Fecal samples of ten hedgehogs, Hemiechinus auritus from Taiz Governorate, Yemen were examined for coccidian parasites. Four (40%) were infected with Eimeria spp. Comparison of oocyst's criteria with other species of Eimeria indicated a new eimerian, E. yeminii n.sp. besides the previously described species, E. auriti Mirza, 1970 reported in Iraq. Oocysts of E. yeminii n.sp. are ovoidal to ellipsoidal, measuring 30 x 24.5 microm (27-36 x 20-28). The outer boundary is bilayered with a light reddish colour and perforated by a micropyle. Oocyst residuum and polar granules are present. Sporocysts are spherical in shape 10 x 7.5 microm (11-12.2 x 10-11.2) with granular residuum and Stieda body. Sporozoites are elongate, lying length-wise to the sporocyst long axis. Sporulation takes place within 3-4 days at approximately 26 degrees C. E. auriti Mirza, 1970 is characterized by subspherical oocysts measuring 20 x 17 (22-26 x 16-19.5) microm, a micropyle and oocyst residuum. The oocyst wall is bilayered, smooth and greenish in colour. Sporocysts are subspherical, measuring 9.0 x 8.3 (8.5-1 x 7.5-8) microm with granular residuum and Stieda body. Fully sporulated oocysts are observed within 48 h at approximately 26 degrees C.
