Distribution: Japan (Hokkaido, Honshu, Shikoku, Kyushu), China (Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Guangdong, Guangxi, Yunnan, Sichuan), Russia (Sakhalin), new to Vietnam (Quang Binh).

New records:

Material examined: 4 ♂ . – CHINA. Sichuan Province: Qionghai Lake, Wetland Park , 27°51.204N 102°15.915E, 5156 ft, 06.06.2011, 1 ♂ leg. J.S. Ascher, L. Ding, Z. Niu, J.G. Rozen. – VIETNAM. Quang Binh Province: Cha Lo , 17°42N 105°46E, 298 m, 14– 17.04.1998, 3 ♂ leg. J.M. Carpenter.

Discussion: The range of variability in characters of this widely distributed species has not previously been investigated. Specimens examined from China (Sichuan) and Vietnam differ from the better studied Japanese specimens in that the structure of the integument is coarser. In particular, the punctation on the mesopleurae are clearly larger and tergum 1 is sparsely, finely punctate ( Fig. 23 ).
