External morphology of the sperm of Hyalomma marginatum (Acarina: Ixodidae).
Mature sperm cells of the tick Hyalomma marginatum were studied by means of scanning electron microscopy. The cell tapering end is transformed into a hemispherical structure. The rest of the cell surface is covered by longitudinal cellular processes, at the tip of the tapering end of the sperm cell an invaginated acrosomal canal can be seen.
