A new genus and species of isosporoid coccidium from captive green tree frogs, (Anura: Hylidae).

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.
