Specimens examined. Holotype: ♂, CHINA, Yunnan Province, Mt. Zixi , 2300m, Alnus nepalensis , 12-XI- 1999, coll. I. Dworakowska. Paratype: 4♂ 2♀, CHINA, Yunnan Province, Mt. Zixi , 2400m, Alnus nepalensis , 10- XI-1999, coll. I. Dworakowska ; 6♂ 1♀, CHINA, Yunnan Province, Dali , 2300m, Alnus nepalensis , 12-XI-1999, coll. I.
