Two new species of coccidia, Eimergia gourai sp. nov. from the Victoria crowned pigeon (Goura victoria Fraser) and Eimeria duculai sp.nov. from the Torres Strait imperial pigeon (Ducula spilorrhoa Gray) have been described. Eimeria gourai oocysts are spherical to sub-spherical in shape, measure 20.0 (19.0-22.0) x 20.0 (18.0-21.0) micrometer and are devoid of micropyle and oocyst residuum. Elongate sporocysts are 12.0 x 5.5 micrometer, and contain a granular residuum. Eimeria duculai oocysts are broadly ovoid with an inconspicuous micropyle at the narrower end. They are 28.0 (26.0-31.0) x 25.0 (23.0-27.0) microgram in size, without residuum but with a membrane-bound polar granule. The elongate sporocysts are 15.5 x 7.2 microgram, with prominent Stieda body and granular, membrane-bound residuum. The morphological characteristics of the known coccidian oocysts from birds of the avian order Columbiformes are reviewed.
已描述了两种新的球虫，即来自维多利亚凤冠鸠（Goura victoria Fraser）的古氏艾美耳球虫（Eimergia gourai sp. nov.）和来自托雷斯海峡皇鸠（Ducula spilorrhoa Gray）的杜氏艾美耳球虫（Eimeria duculai sp. nov.）。古氏艾美耳球虫的卵囊呈球形至亚球形，大小为20.0（19.0 - 22.0）×20.0（18.0 - 21.0）微米，无微孔和卵囊残体。细长的孢子囊为12.0×5.5微米，含有颗粒状残体。杜氏艾美耳球虫的卵囊宽卵形，在较窄的一端有不明显的微孔。其大小为28.0（26.0 - 31.0）×25.0（23.0 - 27.0）微克，无残体但有膜结合的极粒。细长的孢子囊为15.5×7.2微克，有明显的斯氏体和颗粒状、膜结合的残体。对鸽形目鸟类已知球虫卵囊的形态特征进行了综述。
