Description:
The penis-stilette is unusually small for an animal of this size. It measures 35micro in length. Morphologically, the stilette is a simple, curved, funnel-like tube with a sub-terminal opening which is subtended by the pointed end. The sperm-cell is spindle-shaped. Two setae are present and there is a very large undulating 'Mittelrippe' on the mid-line of the surface of the cell extending from feeler to 'tail'. Chromatin material is not visible in this sperm-cell. p. 132/133
