A new species, Eimeria tiliquae n. sp. is described from a shingleback skink (Tiliqua rugosa rugosa). Sporulated oocysts (n=50) are spherical to subspherical, with colourless trilaminate oocyst wall, 0.7±0.1 (0.5-0.75) thick. Oocyst with 4 spheroidal to subspheroidal sporocysts. Oocyst length, 13.7±0.9 (12.0-16.3); oocyst width, 12.8±0.9 (11.5-15.0); oocyst length/width (L/W) ratio, 1.07±0.05 (1.0-1.2). Micropyle, oocyst residuum and polar granule absent. Sporocysts with globular sporocyst residuum and 2 sporozoites. Sporocyst length, 6.0±0.6 (5.0-7.5); sporocyst width, 5.4±0.6 (4.0-7.0); sporocyst L/W ratio, 1.11±0.11 (1.0-1.5). Stieda, parastieda and substieda bodies absent. Phylogenetic analysis of 18S rRNA sequences indicated that E. tiliquae n. sp. shared 96.4-96.5% genetic similarity to E. tropidura, its closest relative. Reptile-derived sequences were not available for the mitochondrial cytochrome oxidase gene (COI) and phylogenetic analysis at this locus placed E. tiliquae n. sp. in a clade by itself but grouping closest (92% similarity) with a novel isolate from a King's skink (Egernia kingii) from Western Australia. Based on morphological and molecular data, this isolate is a new species of coccidian parasite that to date has only been found in shingleback skinks.

D004539	Eimeria	A genus of protozoan parasites of the subclass COCCIDIA. Various species are parasitic in the epithelial cells of the liver and intestines of man and other animals.	Eimerias
D005243	Feces	Excrement from the INTESTINES, containing unabsorbed solids, waste products, secretions, and BACTERIA of the DIGESTIVE SYSTEM.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D033661	Oocysts	Zygote-containing cysts of sporozoan protozoa. Further development in an oocyst produces small individual infective organisms called SPOROZOITES. Then, depending on the genus, the entire oocyst is called a sporocyst or the oocyst contains multiple sporocysts encapsulating the sporozoites.	Sporocysts,Oocyst,Sporocyst
