Large numbers of coccidian oocysts belonging to the genus Isospora were obtained from the intestinal contents of ten legless lizards Diplometopon zarudnyi collected from eastern region, Saudi Arabia. The oocysts are spherical to subspherical, 33.3 x 30.9 (28.6-35.2 x 26.8-32.7) microns with a bilayered wall 1.4 (1.3-1.6) microns thick. Micropyle, polar granule and oocyst residuum are absent. The sporocysts are ellipsoid, 20.1 x 13.8 (17.5-22.3 x 12.2-15.4) microns. A sporocyst residuum, stieda and substieda bodies are present. Sporozoites are banana shaped, blunt at one end and tapered at the other and containing spherical anterior and posterior refractile bodies of the same size. Since this Isospora sp. does not resemble, any other species of Isospora previously described from lizards of the genus Diplometopon, it has been named Isospora diplometoponi n.sp. after the host generic name.
从沙特阿拉伯东部采集的10只无腿蜥蜴（双额凹尾蜥）的肠道内容物中获得了大量属于等孢球虫属的球虫卵囊。卵囊呈球形至亚球形，大小为33.3×30.9（28.6 - 35.2×26.8 - 32.7）微米，具双层壁，厚1.4（1.3 - 1.6）微米。无微孔、极粒和卵囊残体。孢子囊呈椭圆形，大小为20.1×13.8（17.5 - 22.3×12.2 - 15.4）微米。有孢子囊残体、斯氏体和副斯氏体。子孢子呈香蕉形，一端钝圆，另一端渐细，含有大小相同的球形前后折光体。由于这种等孢球虫与先前从双额凹尾蜥属蜥蜴中描述的任何其他等孢球虫物种都不相似，因此以宿主属名命名为双额凹尾蜥等孢球虫新种（Isospora diplometoponi n.sp.）。
