Polyphylla (Granida) minor Nomura, 1977: 104.

Type locality.

"Wushe, Hotso, Taiwan".

Type material not examined.

Additional material examined.

Formosa (Tchaj-wan), Nantou, Wushe, 1.6.-6.6.2002, Jar. Dalihod leg., 1 male in RSCV; Formosa (Tchaj-wan), Nantou, Wushe, 4.6.-6.6.2004, Jar. Dalihod leg., Jana Dalihodová Baštová leg., 2 males in RSCV; China, Yunnan prov., Kunming - Xishan, 19. 5. 1993, L. Bocák lgt., 1 male in PPCB.

Diagnosis.

Polyphylla (Granida) minor and Polyphylla (Granida) nikodymi share similar shape of antennomere 3 (rather short, only twice as long as antennomere 2 and with distinct anterodistal tooth). These species are easily separated by the shape of the male genitalia Figs 6-7 and Figs 9-10) and by the scaly pattern on pygidium (the pygidium is impunctate and bare along midline in Polyphylla (Granida) minor , while it is entirely covered with recumbent scales in Polyphylla (Granida) nikodymi ).

Distribution.

Taiwan. Recorded from Yunnan province of China for the first time.

Remarks.

The specimen from Yunnan slightly differs from those from Taiwan by the shape of whitish scales on pronotum and elytra that are slightly broader. No relevant differences were found in the shape of male genitalia. If these morphologic characters were constant in other specimens coming from the same area, it would be reasonable to assume a subspecific status of the population from Yunnan. However, the material available is insufficient to decide whether such differences fall within the intersubspecific variability.

Although we were not able to study type material of Polyphylla (Granida) minor , all three males from Taiwan examined by us were collected from the type locality of this species.
