Material examined. Holotype 3, China , Yunnan Prov., Simao, 7 April 1981 , Li Fasheng ( CAU ). Paratypes : 13, Thailand , Chiang Mai, Doi Chiang Dao WS Nature Trail, 19º24.187'N 98º55.312'E , 491m , Malaise trap 31.vii-7.viii.2007 , Songkrant Jagsu & Apichat Watwanich, T2829 ( QSBG ); 13, Thailand , Chiang Mai, Doi Chiang Dao WS Nature trail, 19º24.278'N 98º55.311'E , 491m , Malaise trap 30.ix-7.x.2007 , Songkran & Apichart, T3174 ( INHS ).
