Between September and November 1991, 54 adult skinks from 15 species were collected by hand or blowpipe from several localities on Rarotonga, Cook Islands, Ovalau Island, Fiji, and Papua New Guinea (PNG), and their feces were examined for coccidians. Species included 5 seaside skinks (Emoia atrocostata), 1 Pacific blue-tailed skink (Emoia caeroleocauda), 2 Fiji slender treeskinks (Emoia concolor), 15 white-bellied copper-striped skinks (Emoia cyanura), 1 Bulolo River forest skink (Emoia guttata), 6 dark-bellied copper-striped skinks (Emoia impar), 5 Papua five-striped skinks (Emoia jakati), 2 Papua slender treeskinks (Emoia kordoana), 3 Papua robust treeskinks (Emoia longicauda), 1 brown-backed forest skink (Emoia loveridgei), 3 Papua black-sided skinks (Emoia pallidiceps), 2 Papua white-spotted skinks (Emoia physicae), 2 Papua yellow-head skinks (Emoia popei), 1 Papua brown forest skink (Emoia submetallica), and 5 Fiji barred treeskinks (Emoia trossula) Species of Eimeria (Ei.) were detected from these Emoia (Em.) spp. and are described here as new. Oocysts of Eimeria iovai n. sp. from Em. pallidiceps from PNG were ellipsoidal with a bilayered wall (L × W) 26.5 × 18.1 μm, with a length/width ratio (L/W) of 1.1. Both micropyle and oocyst residuum were absent, but a fragmented polar granule was present. This eimerian also was found in Em. atrocostata from PNG. Oocysts of Eimeria kirkpatricki n. sp. from Em. atrocostata from PNG were ellipsoidal with a bilayered wall, 18.6 × 13.5 μm, L/W 1.4. A micropyle and oocyst residuum were absent, but a fragmented polar granule was present. This eimerian was also shared by Em. cyanura from the Cook Islands and Fiji, Em. impar from the Cook Islands, Em. loveridgei from PNG, Em. pallidiceps from PNG, Em. popei from PNG, and Em. submetallica from PNG. Oocysts of Eimeria stevejayuptoni n. sp. from Em. longicauda were subspheroidal to ellipsoidal with a bilayered wall, 18.7 × 16.6 μm, L/W 1.1. A micropyle and oocyst residuum were absent, but a fragmented polar granule was present. Oocysts of Eimeria emoia n. sp. from Em. longicauda from PNG were cylindroidal with a bilayered wall, 29.2 × 15.7 μm, L/W 1.9. A micropyle and oocyst residuum were absent, but a polar granule was present. These are the first eimerians reported from Emoia spp. and they add to our growing knowledge of the coccidian fauna of scincid lizards of the South Pacific.
1991年9月至11月期间，从库克群岛的拉罗汤加、斐济的奥瓦劳岛以及巴布亚新几内亚（PNG）的多个地点，通过徒手或吹管采集了15种54只成年石龙子，并对它们的粪便进行了球虫检查。这些物种包括5只海滨石龙子（Emoia atrocostata）、1只太平洋蓝尾石龙子（Emoia caeroleocauda）、2只斐济细树石龙子（Emoia concolor）、15只白腹铜纹石龙子（Emoia cyanura）、1只布洛洛河森林石龙子（Emoia guttata）、6只黑腹铜纹石龙子（Emoia impar）、5只巴布亚五线石龙子（Emoia jakati）、2只巴布亚细树石龙子（Emoia kordoana）、3只巴布亚粗壮树石龙子（Emoia longicauda）、1只棕背森林石龙子（Emoia loveridgei）、3只巴布亚黑边石龙子（Emoia pallidiceps）、2只巴布亚白斑石龙子（Emoia physicae）、2只巴布亚黄头石龙子（Emoia popei）、1只巴布亚棕森林石龙子（Emoia submetallica）以及5只斐济带纹树石龙子（Emoia trossula）。从这些埃莫伊石龙子属（Emoia）物种中检测到艾美耳属（Ei.）的物种，并在此作为新物种进行描述。来自巴布亚新几内亚的Em. pallidiceps的艾美耳球虫新种（Eimeria iovai n. sp.）卵囊呈椭圆形，具双层壁，大小为（长×宽）26.5×18.1μm，长宽比（L/W）为1.1。微孔和卵囊残体均缺失，但有一个破碎的极粒。这种艾美耳球虫也在来自巴布亚新几内亚的Em. atrocostata中发现。来自巴布亚新几内亚的Em. atrocostata的艾美耳球虫新种（Eimeria kirkpatricki n. sp.）卵囊呈椭圆形，具双层壁，大小为18.6×13.5μm，L/W为1.4。微孔和卵囊残体均缺失，但有一个破碎的极粒。来自库克群岛和斐济的Em. cyanura、来自库克群岛的Em. impar、来自巴布亚新几内亚的Em. loveridgei、来自巴布亚新几内亚的Em. pallidiceps、来自巴布亚新几内亚的Em. popei以及来自巴布亚新几内亚的Em. submetallica也都有这种艾美耳球虫。来自Em. longicauda的艾美耳球虫新种（Eimeria stevejayuptoni n. sp.）卵囊近球形至椭圆形，具双层壁，大小为18.7×16.6μm，L/W为1.1。微孔和卵囊残体均缺失，但有一个破碎的极粒。来自巴布亚新几内亚的Em. longicauda的艾美耳球虫新种（Eimeria emoia n. sp.）卵囊呈圆柱形，具双层壁，大小为29.2×15.7μm，L/W为1.9。微孔和卵囊残体均缺失，但有一个极粒。这些是首次报道的来自埃莫伊石龙子属物种的艾美耳球虫，它们增加了我们对南太平洋石龙子科蜥蜴球虫动物群的认识。
