Choleomeiria riyadhae sp.n. (apicomplexa : eimeriadae)‎ from the lizard, sciincus scincus (Sauria : sciincidae)‎ in Saudi Arabia

Abstract EN

Choleoimeria riyadhae species new was described from the gall bladder of the lizard, Scincus scincus(Sauria: Scincidae) collected from east of Riyadh City, Central Region.

Sporulated oocysts are broadly ellipsoid, 36.8x30.5(33.4-39.1x28.7-32.5)um, with a smooth, brownish-yellow bilayered wall; the shape index(L \ w) is 1.21(1.19-1.23um.

Micropyle, polar granule and oocyst residuum are absent.

Sporocysts are elongate-ellipsoid, 14.8x9.1(13.7-15.5x8.1-10.4) um with shape index(L \ w), 1.63(1.52-1.74) um.

Sporocyst residuum is present.

The sporocysts lack a Stieda body.

Sporozoites are banana-shaped blunt at one end and slightly tapered at the other.

Sometimes, free sporozoites were seen within oocysts
