Meganola weixiensis sp. nov. ( Figs 7–11 )

Material Examined. Holotype. Male, Yunnan Prov., Weixi, 2150 m, 17.vii.2014, Legs. Min Wang, Hailing Zhuang & Zhenfu Huang . Paratypes. 1 male, with the same date as the holotype; 1 female, Shennongjia , 1700 m, Hubei Prov., 19.viii.2014, Legs. Min Wang, Lu Wan & Lanlan Huang.

Diagnosis. Externally, M. weixiensis is close to M. argentescens , but the new species has the bigger brown marking at medial line area and the grayish brown postmedial and subterminal lines compared with M. argentescens , which has the smaller and black marking at medial line area, the feeble postmedial line and the black subterminal line. In male genitalia, the new species differs from M. argentescens by the shorter uncus, the pointed apically and dentoid dorsally harpe and the shorter aedeagus, while M. argentescens has the longer uncus, the shorter and finger-shaped harpe without dentation and the longer aedeagus.
