Description:

Eyes 8 x 9 micrometer. The distal end of the penis stylet is bent so that the angle between this and the main axis is slightly less than a right-angle. The distal opening is oblique. The walls of the tube are of even thickness. A distinctive notch is present in one of the walls near the proximal opening (D). p. 54
