Odontorrhina is a genus of flower chafer beetles comprising four species and two subspecies. The bodies of all species are heavily covered with small bristles (setae), and they are believed to be most closely related to the genus Trichostetha. Members of the genus have been recorded exclusively from the South African provinces of the Northern and Western Cape, aside from one unconfirmed record from southern Namibia. They are endemic to the Fynbos and Succulent Karoo regions.
