title: Morphological characteristics of a new species of Haemogregarina Danilewsky, 1885 (Apicomplexa: Adeleorina) in naturally infected Acanthodactylus                      boskianus (Daudin) (Sauria: Lacertidae) in Egypt.
abstract: This paper describes the morphological characteristics of a new species of Haemogregarina Danilewsky, 1885, from naturally infected Acanthodactylus boskianus (Daudin) in Egypt, based on both blood and tissue stages. The prevalence of infection was found to be 66% (33/50). The blood stages were found to be confined to the erythrocytes and could be differentiated into small and large forms. The small form (trophozoites) measures 8 × 3.5 μm, whereas the large form (mature gamonts) measures 12 × 5 μm. The tissue stages were observed only in the liver. Meronts occurred within parasitophorous vacuoles in hepatocytes and ranged from mononucleate forms to mature forms that contained c.10-15 merozoites.
