| 41. | A 5-sided areolet, a short sternaulus, and a puffy face with a convex clypeus are diagnostic characters for most members of this large subfamily.
|
| 42. | The post-clypeus is a large nose-like structure that lies between the eyes and makes up much of the front of the head in cicadas.
|
| 43. | It then extracts its head and clypeus by hunching its body, and when these have emerged, arches back to draw the legs out of their casing.
|
| 44. | The labrum is a broad lobe forming the roof of the preoral cavity, suspended from the clypeus in front of the mouth and forming the upper lip.
|
| 45. | In the " higher " Diptera the head has a subglobose shape and the fronto-clypeus is an area bounded superiorly by the eyes and the vertex.
|
| 46. | Head, thorax, and node are red, the legs are a yellowish-red colour, and the mandibles and clypeus are a reddish-yellow colour.
|
| 47. | The cheeks below the antennae, a small spot behind each eye, a bilobate spot on the clypeus, and the mandibles ( except the apex ) are yellow.
|
| 48. | Its mandibles, ( most of ) clypeus, prothorax, mesothorax, posterolateral areas are all light red, while its abdomen and much of its head is black.
|
| 49. | "Protonectarina " is characterized by its relatively hairy eyes, and can be diagnosed by the width of the clypeus, or the front of the head.
|
| 50. | It is very similar to the common wasp ( " V . vulgaris " ), but unlike the common wasp, has three tiny black dots on the clypeus.
