Fecal samples of 36 ground squirrels, Spermophilus beldingi, from Tioga Pass (elev. ca. 3315 m) in the Sierra Nevada, California, yielded oocysts of Eimeria beckeri in nine squirrels, E. citelli in four squirrels, E. beldingii n. sp. in two squirrels, and degenerated, unidentifiable oocysts in ten squirrels. Eimeria beldingii n. sp. oocysts are ellipsoidal, 30-34 X 24-30 (mean 32 X 26) micron with a two-layered, rough, striated wall, without a micropyle or residuum, with polar granules; they contain ellipsoidal or ovoid sporocysts 11-15 X 9-12 (mean 13 X 10) micron with a Stieda body and residuum.
从加利福尼亚内华达山脉蒂奥加山口（海拔约3315米）采集的36只贝氏黄鼠的粪便样本中，9只松鼠体内检出贝克艾美耳球虫的卵囊，4只松鼠体内检出 Citelli艾美耳球虫，2只松鼠体内检出新种贝氏艾美耳球虫，10只松鼠体内的卵囊已退化、无法鉴定。新种贝氏艾美耳球虫卵囊呈椭圆形，大小为30 - 34×24 - 30（平均32×26）微米，壁为两层，粗糙，有条纹，无微孔或残体，有极粒；它们含有椭圆形或卵形的孢子囊，大小为11 - 15×9 - 12（平均13×10）微米，有斯氏体和残体。
