Material examined.

A total of 19 specimens (15 males and 4 females in cBL&KB and ZIN) were examined from the following localities: China. Yunnan: Xinping County: 1 female, Ailaoshan Mt. Range, W Shuitangzhen Town, 24°08'24"N, 101°25'16"E, 1940 m, 2.VI.2011, I. Belousov, I. Kabak & A. Korolev leg. (cBL&KB); 15 males, 3 females, SSE Shuangjiang Town, 23°22'22"N, 99°54'47"E, 2540 m, 22.VI.2011, I. Belousov, I. Kabak & A. Korolev leg. (cBL&KB, ZIN).

Distribution.

The geographical range of Chydaeus similis in China extends from Central Sichuan to Yunnan. In Yunnan, it had been recorded previously only from the Gang Shan (Mountains) ( Kataev and Schmidt 2002). Based on the new records reported here ( Fig. 63 ), Chydaeus similis is more widely distributed in Yunnan.

Remarks.

Like the preceding species, Chydaeus similis belongs to the bedeli group ( Kataev and Schmidt 2002). In specimens of Chydaeus similis from Yunnan, the denticles at the pronotal basal angles are small and only slightly prominent, smaller in most specimens than in Yunnan specimens of Chydaeus bedeli vietnamensis , members of which are very similar in habitus to Chydaeus similis and occur in the same area.
