Abstract

A new genus and a new species of isosporoid coccidium (Apicomplexa: Conoidasida: Eimeriorina) are described and illustrated from green tree frogs (Ranoidea caerulea) (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 Isospora 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 c 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.

圈养绿树蛙异孢子球虫一新属、新种（无尾目：水螅科）。

描述了从巴布亚新几内亚和印度尼西亚进口的绿树蛙（Ranoidea caerulea）（无尾目：水螅科）中发现的异孢子类球虫（顶复体目：Conoidasida: Eimeriorina）一新属和一新种。所描述的种有散孢子囊和四孢子代卵囊，没有孢子体。从无尾目（Anura）中描述的原属于Eimeriidae Minchin， 1881年的Isospora Schneider属的9种被认定为新属成员，并提出了新的种名组合。绿树蛙异孢子体卵囊18S rRNA部分基因片段和线粒体细胞色素c氧化酶亚基1基因的系统发育分析表明，无尾动物无孢子体的异孢子体卵囊应归入肉囊科，不再属于卵囊科。

期刊介绍： The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
