Abstract

Isospora elmahalensis n. sp. is described from the Saudi Arabian bird, Pycnonotus leucogenys, from the Elmahala valley. Sporulated oocysts of I. elmahalensis were spherical or nearly subspherical, 19.5-22.5 X 18.5-20 (21.34 +/- 0.4 X 19.06 +/- 0.5) microns. Oocysts lacked a micropyle, residuum, and polar granule. Sporocysts were ovoid, 14-17.5 X 7-12 (16.08 +/- 1.05 X 9.9 +/- 1.55) microns, and had a Stieda body and sporocyst residuum, but lacked a substiedal body. Sporozoites were elongated with a clear globule at one end. The host bird belongs to the order Passeriformes.
