Holotype ♂, China, Yunnan, Baoshan, Gaoligong National Nature Reserve, Nankang Station, light, Yunlan Jiang & Lu Yue (CAU). Paratypes: 99♂ 6♀, same as holotype (CAU). Etymology. The specific epithet ‘ abdominata ’ refers to the extremely long male sterna VIII + IV in the new species. Distribution. China (Yunnan). Remarks. This species can be distinguished easily from C. ciliata by the pale crossveins, from C. orientalis by the markings on thorax and from C. obliquata by the presence of extremely long male sterna VIII + IV.
