P. fortunei - China
P. fortunei nitida - Vietnam
P. japonica - Japan, Korea, China
P. japonica tonkiniana - North Vietnam

Genus Rhomborrhina is generally confined to the area from Japan through China through Malaysia and to India. Because the Taiwanese exported many, many thousands of these beetles during the l970s, most collections of worldwide exotic beetles are certain to contain several examples of this genus. The number of recognized subspecies is noted in parentheses in the following list of the species in the genus:

SPECIES - - - - - - LOCATION
R. resplendens(3) --- China to India
R. gigantea --- Sunda Islands
R. mellyi(4) --- China, India, Viet Nahm
R. gestroi --- Assam & Shillong
R. violacea --- China
R. formosana --- Taiwan
R. unicolor(2) --- Japan, China, Tibet
R. splendida --- Taiwan
R. polita --- China(?), Japan
R. jeanneli --- China
R. microcephala --- India
R. hiekei --- China
R. hamai --- Ishigaki Island(Japan)

Genus Torynorrhina is closely related to the Rhomborrhina genus. By studying the Mesosternal process on the underside of the beetle, one can separate the two genera. The Anomalocera and Pseudotorynorrhina genus are also related:

Rhomborrhina - the final plate is about as wide as long.
Torynorrhina - the final plate is much wider than long, and is about twice as large as the plate in Rhomborrhina.

The following species are found in the Torynorrhina genus:

Species - - - - - Location
T. thiemei - North Vietnam, China
T. fulvopilosa - North Vietnam, China
T. opalina - North India, Tibet
T. pilifera - Taiwan
T. hyacinthina - India to Thailand
T. flammea - Burma, China, India
T. distincta - India, China, etc.
T. apicalis - North India, Himalayan
T. laotica - Laos
T. scutellata - North Vietnam

The Trigonophorus genus is closely related to the Rhomborrhina group, but both the male and female have a small distinctive paddle at the end of their head. The following species are found in the Trigonophorus genus:
