G). The stylet proper is 30 µm long and has a cup-shaped, 12 - µm-wide proximal part and a curved and slender distal part. At the convex side of the cup-shaped part, the stylet carries a perpendicularly-bent, spine-like projection, which is 18 µm long. Additionally, the proximal part of the stylet also carries a 35 µm-long, bent, plate-like part, which is very slender proximally with a distal rectangular part, giving it the overall appearance of a golf club.
