( Fig. 8 View FIGURES 6–8 )

Type species: Coptorhina africana Hope, 1833 View in CoL (synonym of C. klugi Hope, 1833 View in CoL )

Coptorhina View in CoL species are convex and range from 8.0–20.0 mm in length (see description in Frolov et al. 2008). They can be readily recognized by a combination of two characters: a distinctly bidentate clypeus, and a somewhat rectangular metepisternon, which is widest posteriorly with a secondary suture, and very convex epipleural margin. Elytra are fused at the sutural margin and are only slightly raised before flight with the hind wings being unfurled through the cleft in the pleural margin. The revision of Frolov et al. (2008) reduced the total of valid Coptorhina View in CoL species to seven after recognizing a further 10 species and one subspecies as synonyms due to the great morphological variation in body size. Although similar to female and some larger male Frankenbergerius View in CoL with weakly developed clypeal processes, they may be separated by the rectangular ( Coptorhina View in CoL ) versus triangular shape ( Frankenbergerius View in CoL ) of the metepisternon.
