A novel Eimeria sp. was identified in faeces collected from a King's skink (. Egernia kingii) housed at the Kanyana Wildlife Rehabilitation Centre in Western Australia. Oocysts measure 17.0 × 15.0μm with a length/width ratio (L/W) of 1.13. Phylogenetic analysis of 18S rRNA sequences indicated that the novel Eimeria sp. shared the highest genetic similarity to Eimeria antrozoi and Eimeria rioarribaensis from vespertilionid bats from North America (s≥98.9%). At the COI locus, bat-derived sequences were not available and phylogenetic analysis placed the novel Eimeria sp. in a clade by itself and shared 98.8% similarity with the rodent-derived species E. falciformis and E. vermiformis. This suggests that the isolate from the King's skink's faeces was probably derived from a mammal, possibly a rodent or a bat.
