Genus Odontorrhina Burmeister, 1842

Odontorrhina: Burmeister 1842: 396 ; Lacordaire 1856: 522, 528; Schoch 1894: 215; Péringuey 1907: 327, 363; Schenkling 1921: 302; Marais & Holm 1989: 13; Holm & Marais 1992: 120; Rigout & Allard 1992: 59; Sakai & Nagai 1998: 303.

Type species: Cetonia pubescens Olivier, 1789 , by subsequent designation ( Marais & Holm 1989).

Diagnosis:Apart from an unconfirmed record of O. pubescens in southern Namibia ( Marais & Holm 1989; Holm & Marais 1992), all species of the genus appear to be restricted to the Western and Northern Cape provinces of South Africa. According to Holm and Marais (1992), the genus may be most closely related to Trichostetha Burmeister, 1842 , which also exhibits the bulk of its taxonomic diversity in the Cape provinces and, more specifically, the Cape Floral Region. The two genera also share a heavily setose body and a variably developed white band on the lateral pronotal margins. Odontorrhina is, however, unique in having two pointed and upturned denticles on the anterior margin of the clypeus. It differs further from Trichostetha by exhibiting elytra that are invariably without any cretaceous spots and a metallic sheen, both on the dorsal and ventral sides (the latter character is absent in O. krigei Schein, 1950 ).
