Two new species of coccidian parasites are described from African reptiles. Oocysts of Eimeria foulshami sp. n. from the plated lizard Gerrhosaurus major bottegoi Del Prato of Sudan are ellipsoidal, 24.1 x 14.9 (23-26.5 x 14-17.8) microm with a bilayered, colourless oocyst wall and lack polar granules. The ellipsoidal sporocysts average 8.6 x 4.6 (7-10.6 x 4.4-7) microm and possess a prominent, globular, sporocyst residuum. Oocysts of Caryospora regentensis sp. n. from the Eastern green mamba Dendroaspis augusticeps Smith, 1849 [corrected] of Kenya are spherical to subspherical, 16.8 x 16.4 (16-17.6 x 15-17.2) microm with a bilayered oocyst wall and a single polar granule. The ellipsoidal sporocysts average 13.0 x 10.3 (10.2-14 x 9.2-11) microm and possess a Stieda and substieda body and a prominent globular sporocyst residuum. Oocysts of Caryospora legeri Hoare, 1933 are reported from a hissing sand snake, Psammophis sibilans sibilans L. from Nigeria, representing a new geographical record. The oocysts are slightly larger than the type, but otherwise identical. Caryospora psammophi Bray, 1960 and C. hermae Bray, 1960 from Psammophis sibilans phillipsi, oocysts of which are morphologically similar to and overlap in dimensions with C. legeri Hoare, 1933, are synonymised with the latter species. Eimeria samiae Iskander et Tadros, 1979 is emended to E. samyadeli to reflect the gender of the person the species was named after and because E. sani is preoccupied. In addition to these findings, Eimeria bohemi Modrý, Slapeta et Koudela, 2000 and oocysts of an unidentified spherical Eimieria sp. are reported from Chamaeleo dilepis dilepis Leach from Cameroon.
从非洲爬行动物中发现了两种新的球虫寄生虫。来自苏丹的大板蜥（Gerrhosaurus major bottegoi Del Prato）的福氏艾美耳球虫（Eimeria foulshami sp. n.）卵囊呈椭圆形，大小为24.1×14.9（23 - 26.5×14 - 17.8）微米，卵囊壁为双层、无色，且无极粒。椭圆形的孢子囊平均大小为8.6×4.6（7 - 10.6×4.4 - 7）微米，有一个明显的球形孢子囊残体。来自肯尼亚的东部绿曼巴（Dendroaspis augusticeps Smith, 1849 [已校正]）的雷根卡里孢子虫（Caryospora regentensis sp. n.）卵囊呈球形至亚球形，大小为16.8×16.4（16 - 17.6×15 - 17.2）微米，卵囊壁为双层，有一个极粒。椭圆形的孢子囊平均大小为13.0×10.3（10.2 - 14×9.2 - 11）微米，有斯氏体和亚斯氏体以及一个明显的球形孢子囊残体。1933年霍雷描述的莱氏卡里孢子虫（Caryospora legeri）的卵囊在尼日利亚的嘶嘶沙蛇（Psammophis sibilans sibilans L.）中被发现，这代表了一个新的地理记录。这些卵囊比模式标本略大，但其他方面相同。1960年布雷描述的沙蛇卡里孢子虫（Caryospora psammophi）和赫氏卡里孢子虫（C. hermae），其卵囊在形态上与1933年霍雷描述的莱氏卡里孢子虫相似且大小有重叠，现被归为后一种的同物异名。1979年伊斯坎德尔和塔德罗斯描述的萨米亚艾美耳球虫（Eimeria samiae）现修订为萨米亚德艾美耳球虫（E. samyadeli），以反映该物种命名所依据的人物性别，并且因为“E. sani”已被占用。除了这些发现外，还在喀麦隆的德氏避役（Chamaeleo dilepis dilepis Leach）中发现了2000年莫德里、斯拉佩塔和库德拉描述的波希米亚艾美耳球虫（Eimeria bohemi）以及一种未鉴定的球形艾美耳球虫属（Eimieria sp.）的卵囊。
