Macrostomum glochistylum Fig 13-19.jpg
Edited by nadja.cereghetti on 21. November 2008 - 14:41
The small reniform eyes are not embedded in the tissues of the ganglia. The penis-stilette is a long, curved funnel which extends from a widened proximal base to end in a slightly bent obliquely truncated terminus. The stilette termination is distinctly provided with a thin lip which projects slightly beyond the opening proper. p. 195 The sperm cell in this form is a spindler-shaped structure which is much shorter than usual for Macrostomum. Chromatin granules are present in the anterior region of the cell, while posteriorly directed setae are absent. p. 196

The stylet reaches its termination in a long sharpened point. p. 188 The sperm cells are elongate, undulating bodies which lack the postero-Iateral setae so common to the genus and are possessed of chromatin granules in the anterior part of the cell having the largest caliber. p. 189
