Philippine tarsier (Tarsius syrichta) is a small nocturnal primate from the Philippines. Little is known about tarsier parasites, including coccidia (Apicomplexa: Eimeriidae), a highly prevalent parasitic protist group in all vertebrate classes. Only 7 valid species of the genus Eimeria, seven species of Isospora and 5 species of Cyclospora have been described in Primates. This study extends the number of coccidia known in primates by two new species obtained from faeces of Philippine tarsiers from Bohol Island. The newly described Eimeria syrichta n. sp. and Eimeria boholensis n. sp. differ morphologically from each other as well as from other coccidia reported from primates. Partial DNA sequences of three genes were obtained from oocysts of E. syrichta n. sp. and E. boholensis n. sp., and formed clusters according to their host specificity; however, there are no other sequentional data of coccidia from primates, except for the genus Cyclospora, which clusters inside the chicken eimerians, and Cystoisospora belli, which is phylogenetically related to Sarcocystidae. More molecular data on coccidia infecting primates are needed for further discussion.
菲律宾眼镜猴（Tarsius syrichta）是一种来自菲律宾的小型夜行性灵长类动物。人们对眼镜猴寄生虫了解甚少，其中包括球虫（顶复门：艾美耳科），这是在所有脊椎动物类别中高度普遍的寄生原生生物类群。在灵长类动物中，仅描述了7种有效的艾美耳属物种、7种等孢属物种和5种环孢属物种。本研究从薄荷岛的菲律宾眼镜猴粪便中获得了两个新物种，从而增加了灵长类动物中已知的球虫种类。新描述的西里卡艾美耳球虫（Eimeria syrichta）新种和薄荷艾美耳球虫（Eimeria boholensis）新种在形态上彼此不同，也与灵长类动物中报道的其他球虫不同。从西里卡艾美耳球虫新种和薄荷艾美耳球虫新种的卵囊中获得了三个基因的部分DNA序列，并根据它们的宿主特异性形成了聚类；然而，除了在鸡艾美耳球虫内部聚类的环孢属以及与肉孢子虫科在系统发育上相关的贝氏等孢球虫（Cystoisospora belli）外，没有其他灵长类动物球虫的后续数据。需要更多关于感染灵长类动物的球虫的分子数据来进行进一步讨论。
