The stylet ends slightly inflated, and this expansion is not accompanied by a thickening of the wall. The orifice of the stylet was not seen with certainty, probably it is subterminal. p. 30

The penis-stilette is a funnel with almost a straight main axis and a sharply pointed and bent termination. The terminal portion enclosing the external opening is bent at an angle of 115 degree. The basal proximal rim is unevenly crenated. The sperm cells have a feeler, body region and a thin filamentous tail. Setae are not present. There is a noticeable massing of chromatic granules in the body region of the cell. p. 31

Macrostomum ruebushi var carolinensis Fig 9-10.jpg

The penis-stilette is unique in that the proximal basal portion is not only dentated but is truncated at an oblique angle. This penis funnel is terminally curved and sharply pointed. The opening is terminal on this stilette. p. 27
