Specimens examined. 1 female, Xiaoxing’anling, Heilongjiang Province, July 1995, leg. Shu-Ping Sun. 1Ƥ, Xinbin, Liaoning Province, 20 June 1998, leg. Mao-Ling Sheng. 1Ƥ, Baiyunshan Natural Reserve, 1400 m, Henan Province, 22 July 2003, leg. Gui Xue. 1Ƥ, Chaihe, 374 m, Heilongjiang Province, 21 June 2004, leg. Mao-Ling Sheng.

We also examined the specimens deposited in the Natural History Museum, London (NHM) and the Zoologische Staatssammlung München (ZSM). A group of specimens ( Fig. 5 ) have the same characters as original description: antennae and legs red or reddish brown, hind tarsus black, but another group of specimens (Figs. 3,4) have antenna almost brownish black and coxae black. This is variation within the species.
