| The portion of the face bounded by this groove is called the clypeus. |
| Although the clypeus and labrum of Reboursia exhibit a sphaeromatoid shape, it has a broad separation between the antennular basal articles. |
| It is known that the temperature of the laconicum was regulated by drawing up or down a metallic plate or clypeus. |
| Fabricius has denominated this part the clypeus, in which he has been followed by most modern Entomologists. |
| Their monophyly is undisputed, given the five elongate, stiff mouthpart elements forming a distinctive beak, and an enlarged clypeus. |
| Note the tumid convex clypeus which composes most of the anterior aspect of the head. |
