Six new species of coccidia are described from endangered Phelsuma spp. geckoes (Sauria: Gekkonidae) endemic to Mauritius, Indian Ocean. Five new species (3 Eimeria and 2 Isospora species) are described from Phelsuma rosagularis Vinson et Vinson; all lack a micropyle and an oocyst residuum, and all have a sporocyst residuum. Oocysts of Eimeria swinnertonae sp. n. are ellipsoidal, 22.2 x 17.8 (20.8-24.8 x 16.8-18.4) microm; SI 1.25; polar granule absent. Sporocysts are ellipsoidal, 8.8 x 7.0 (8.0-9.6 x 6.4-8.0) microm; SI 1.3; Stieda body absent. Oocysts of Eimeria stebbinsi sp. n. are ellipsoidal, 17.4 x 11.7 (16.0-19.2 x 11.2-12.8) microm; SI 1.5; polar granules present. Sporocysts are elongate-ellipsoidal, 7.7 x 4.0 (7.2-8.0 x 3.2-5.6) microm; SI 1.9; Stieda body present. Oocysts of Eimeria raleighi sp. n. are spheroidal to sub-spheroidal, 17.0 x 15.5 (16.0-19.2 x 14.4-16.8) microm; SI 1.1; polar granule present. Sporocysts are sub-spheroidal, 7.8 x 6.6 (7.2-8.0 x 6.4-7.2) microm; SI 1.2; Stieda body absent. Oocysts of Isospora cottinghamae sp. n. are ellipsoidal, 19.8 x 15.5 (17.6-21.6 x 14.4-17.6) microm; SI 1.3; polar granules present. Sporocysts are ellipsoidal, 10.8 x 6.9 (9.6-12.8 x 6.4-8.0) microm; SI 1.6; Stieda body present. Oocysts of Isosporapearlae sp. n. are ellipsoidal, 16.0 x 11.5 (15.2-17.6 x 9.6-12.8) microm; SI 1.4; polar granule present. Sporocysts are ellipsoidal, 8.8 x 5.4 (8.0-9.6 x 4.8-6.4) microm; SI 1.6; Stieda and substieda bodies present. One new Eimeria species is described from the blue-tailed day gecko, Phelsuma cepediana Merrem. Oocysts of Eimeria hartleyi sp. n. are sub-spheroidal to ellipsoidal, 18.2 x 14.5 (16.0-20.8 x 13.6-16.0) microm; SI 1.26; polar granules present. Sporocysts are ellipsoidal to cylindroidal, 7.5 x 5.3 (6.4-8.0 x 4.8-6.4) microm; SI 1.4; Stieda body present. We report the presence of tetrazoic spheroidal to sub-spheroidal oocysts or sporocysts 10.2 x 8.5 (9.9-10.4 x 8.3-8.8) microm; SI 1.2 from an individual of P. cepediana. These oocysts or sporocysts are significantly larger than the Cryptosporidium species so far described from reptiles, and likely represent excretion of spuriously ingested sporocysts of a Sarcocystis or Adelina coccidian.
从印度洋毛里求斯特有的濒危日行壁虎属（蜥蜴目：壁虎科）物种中描述了六种新的球虫。从玫瑰喉日行壁虎（Phelsuma rosagularis Vinson et Vinson）中描述了五个新物种（3种艾美耳球虫和2种等孢球虫）；所有物种均无微孔和卵囊残体，均有孢子囊残体。斯温纳顿艾美耳球虫（Eimeria swinnertonae sp. n.）的卵囊呈椭圆形，22.2×17.8（20.8 - 24.8×16.8 - 18.4）微米；孢子化率1.25；无极粒。孢子囊呈椭圆形，8.8×7.0（8.0 - 9.6×6.4 - 8.0）微米；孢子化率1.3；无斯氏体。斯特宾斯艾美耳球虫（Eimeria stebbinsi sp. n.）的卵囊呈椭圆形，17.4×11.7（16.0 - 19.2×11.2 - 12.8）微米；孢子化率1.5；有极粒。孢子囊呈长椭圆形，7.7×4.0（7.2 - 8.0×3.2 - 5.6）微米；孢子化率1.9；有斯氏体。罗利艾美耳球虫（Eimeria raleighi sp. n.）的卵囊呈球形至亚球形，17.0×15.5（16.0 - 19.2×14.4 - 16.8）微米；孢子化率1.1；有极粒。孢子囊呈亚球形，7.8×6.6（7.2 - 8.0×6.4 - 7.2）微米；孢子化率1.2；无斯氏体。科廷厄姆等孢球虫（Isospora cottinghamae sp. n.）的卵囊呈椭圆形，19.8×15.5（17.6 - 21.6×14.4 - 17.6）微米；孢子化率1.3；有极粒。孢子囊呈椭圆形，10.8×6.9（9.6 - 12.8×6.4 - 8.0）微米；孢子化率1.6；有斯氏体。佩拉尔等孢球虫（Isospora pearlae sp. n.）的卵囊呈椭圆形，16.0×11.5（15.2 - 17.6×9.6 - 12.8）微米；孢子化率1.4；有极粒。孢子囊呈椭圆形，8.8×5.4（8.0 - 9.6×4.8 - 6.4）微米；孢子化率1.6；有斯氏体和亚斯氏体。从蓝尾日行壁虎（Phelsuma cepediana Merrem）中描述了一种新的艾美耳球虫。哈特利艾美耳球虫（Eimeria hartleyi sp. n.）的卵囊呈亚球形至椭圆形，18.2×14.5（16.0 - 20.8×13.6 - 16.0）微米；孢子化率1.26；有极粒。孢子囊呈椭圆形至圆柱形，7.5×5.3（6.4 - 8.0×4.8 - 6.4）微米；孢子化率1.4；有斯氏体。我们报告在一只蓝尾日行壁虎个体中发现了大小为10.2×8.5（9.9 - 10.4×8.3 - 8.8）微米、孢子化率1.2的四孢子球形至亚球形卵囊或孢子囊。这些卵囊或孢子囊明显大于迄今为止从爬行动物中描述的隐孢子虫物种，可能代表了偶然摄入的肉孢子虫或艾氏球虫的孢子囊的排泄产物。
