Donald W. Duszynski Robert N. Fisher Christopher C. Austin Chris T. McAllister 2014 Between September 1991 and June 1992, feces from 4 species of tree skinks, <i>Prasinohaema</i> spp. from Papua New Guinea, were collected and examined for coccidia. Two species, <i>P. flavipes</i> and <i>P. prehensicauda</i> were found to harbor eimerians which are described as new. Oocysts of <i>Eimeria krausi</i> sp. nov. from <i>P. flavipes</i> were ellipsoidal to subspheroidal with a smooth bilayered wall and measured (L × W) 19.2 × 16.9 μm, with a length/width (L/W) ratio of 1.1. Micropyle and oocyst residuum were absent but a fragmented polar granule was present. Sporocysts were ellipsoidal, 9.7 × 6.7 μm, L/W of 1.5. Stieda, subStieda and paraStieda bodies were absent. The sporocyst residuum was composed of many small granules in a compact mass between sporozoites. The sporozoites were sausage-shaped, 11.7 × 2.7 μm, in situ, with an ellipsoidal posterior refractile body and a spheroidal anterior refractile body. Oocysts of <i>Eimeria greeri</i> sp. nov. from <i>P. prehensicauda</i> were ellipsoidal with a smooth bilayered wall, (L × W) 23.0 × 18.3 μm, with a L/W of 1.3. Micropyle and oocyst residuum were absent but a fragmented polar granule was present. Sporocysts were ellipsoidal, 9.7 × 8.4 μm, with a L/W of 1.2. Stieda, subStieda and paraStieda bodies were absent. The sporocyst residuum was composed of many large granules in a compact mass between sporozoites. The sporozoites were sausage-shaped, with an ellipsoidal posterior refractile body and a spheroidal anterior refractile body.
