Figure 1

Morphology of cicada ovipositors and the rasping regions. (a–d) are illustrations of cicada ovipositors and their corresponding rasping regions are shown as SEM images on the right side. (a,b) show the ventral side and dorsal side of the ovipositor of N. linnei and (c,d) show the ventral and dorsal side of M. cassinii, respectively. All studied ovipositors consist of medial gonapophyses IX (GIX) and lateral gonapophyses VIII (GVIII). The GVIII covers the lateral sides of the GIX and wraps around the ventral side, covering the entire GIX except at the distal end. The ventral side of the GVIII has lobes (Lo) near the distal tip, which represents where the eggs exit the ovipositor. The medial region of a GIX has ridges (Ri) that interlock with ridges from the other GIX. All studied ovipositors have a rasping region with teeth (singular = tooth, To). The ovipositors were illustrated by Brooke Pandrea.
