stylet tip thickening absent

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

Description:

Eyes 10 x 21 micrometer. The penis stylet is typically in the form of a blunt hook. The walls of the tube around the distal terminal opening are very slightly thicker than the walls in the remaining part of the stylet. p. 52

Description:

The penis stylet is hook-shaped; it is slightly bent in another plane at a point indicated by the arrow. Its walls are not thickened at any particular point. Its distal opening is terminal. p. 53

Description:

The penial tube has a slight bend at its proximal end, and a distinct and sharp bend at its distal end. The distal tip of the stylet is blunt with a terminal opening. The walls appeared of uniform thickness along the length of the tube. p. 56

Description:

Eyes 13 x 25 micrometer. The penis stylet is bow-shaped, gradually tapering in diameter towards the swollen distal end. The walls of the distal end are slightly thickened; the distal opening is displaced slightly to one side of the swollen end and is not exactly terminal. p. 55
