Type locality.

"North China".

New material examined.

China · 2 males; Hubei Prov., Xiangyang City, Xianshan Mountain ; July 2020; Mao Ye leg; SWU-B-CC-010028 to 010029 · 1 male; Hubei Prov., Wuhan City, Huangling District, Sushan Temple ; 16 August 2019; Chen-Liang Li leg.; SWU-B-CC-010030 .

Distribution.

China (Beijing, Hebei, Henan, Inner Mongolia, Liaoning, Jilin, Tianjin, Shaanxi, Shanxi, Ningxia, Shandong, Jiangsu, Anhui, Hubei (new record), Hunan, Chongqing, Guizhou, Yunnan).

Remarks.

This species is newly recorded from Hubei Province. This is the most widely distributed Eupolyphaga species in China, but in general it is more common in Northern China than in the south. The distribution of this species in south China needs to be further surveyed in the future. The ventral abdomen of this species in males is usually uniformly yellowish white, while a specimen from Wuhan City has dark brown markings on the legs and abdomen (Fig. 8B, F ). By sequencing the COI genes of both individuals from Wuhan and northern China (Beijing and Liaoning), we found that the genetic distances between the individuals from Wuhan and north China reached 8.81% (Beijing) to 9.54% (Liaoning); the ABGD analysis treats the Wuhan individual as a separated MOTU from individuals from northern China. Currently only one specimen is available from Wuhan. Therefore, we tentatively regard this variation as an intraspecific difference.
