A new genus and a new species of isosporoid coccidium (Apicomplexa: Conoidasida: Eimeriorina) are described and illustrated from green tree frogs () (Anura: Hylidae) imported from Papua New Guinea and Indonesia. The described species has disporocystic and tetrasporozoic oocysts without a Stieda body. Nine species originally belonging to the genus Schneider, 1881 in the family Eimeriidae Minchin, 1903 described from Anura are recognized as members of the new genus and new combinations of the species names are proposed. The phylogenetic analyses of partial gene fragments of 18S rRNA and mitochondrial cytochrome oxidase subunit 1 genes from isosporoid oocysts from green tree frogs suggested that isosporoid oocysts without Stieda bodies from anurans should be placed in the Sarcocystidae and no longer belong in the Eimeriidae.
本文描述并阐释了从巴布亚新几内亚和印度尼西亚进口的绿树蛙（无尾目：雨蛙科）体内的一种新的等孢子球虫属（顶复门：球虫纲：艾美耳亚纲）及其新物种。所描述的物种具有双孢子囊和四孢子虫的卵囊，无斯氏体。原本属于1881年施耐德属、1903年明钦艾美耳科中从无尾目描述的9个物种被认定为新属的成员，并提出了物种名称的新组合。对绿树蛙等孢子球虫卵囊的18S rRNA和线粒体细胞色素c氧化酶亚基1基因部分基因片段的系统发育分析表明，无尾目无斯氏体的等孢子球虫卵囊应归入肉孢子虫科，不再属于艾美耳科。
