Abstract:Five new species of Eimeria are described from lizards. Eimeria baltrocki n. sp. was found in the berber skink, Eumeces schneideri, from Egypt. The oöcysts are cylindroidal, averaging 38 × 18.3 mgrm, with a single thick oöcyst wall. Most oöcysts possess a single polar granule; a micropyle and oöcyst residuum are absent. The sporocysts are ellipsoidal and average 11.5 × 8.1 mgrm, each with a large, globular sporocyst residuum; the Stieda body is absent. Eimeria anolidis n. sp. is described form the common anole, Anolis carolinensis, from Florida, USA. The oöcysts are cylindroidal and average 31 × 15.8 mgrm with a thick, single-layered oöcyst wall. Two polar granules are usually present; a micropyle and oöcyst residuum absent. The sporocysts are ellipsoidal and average 9.4 × 7.5 mgrm with a globular sporocyst residuum; the Stieda body is absent. Eimeria guyanensis n. sp is recorded in the ameiva, Ameiva ameiva, from Guyana, South America. The oöcysts are spherical to subspherical, average 19.0 × 17.8 mgrm and possess a thick, single-layered oöcyst wall. Numerous polar granules are present (n > 5); a micropyle and oöcyst residuum are absent. The sporocysts are spherical to subspherical, average 7.5 × 7.8 mgrm and possess a compact globular sporocyst residuum; the Stieda body is absent. Eimeria phelsumae n. sp. was recovered from the giant day gecko, Phelsuma madagascariensis grandis, from Madagascar, which harboured a simultaneous infection of E. brygooi. The oöcysts measured 32 × 15 mgrm and are cylindroidal without polar granules, a micropyle or oöcyst residuum, or a Steida body. The sporocysts are ellipsoidal and average 9.8 × 7 mgrm, with a loosely clumped, granular sporocyst residuum; the Steida body is absent. Eimeria leiocephali n. sp. was discovered in the faeces of the ornate ground iguana, Leiocephalus barahonensis, from Haiti. The oöcysts are spherical to subspherical, 21 × 19 mgrm, and contain a number of polar granules (n > 5); a micropyle and oöcyst residuum are absent. The sporocysts are spherical, 8 mgrm in diameter and lack a sporocyst residuum. Eimeria turcicus and E. lineri were found in faeces of Hemidactylus turcicus turcicus from the host's country of origin, Turkey.
