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
).
