Distribution. China (Guangxi, Guizhou, Xizang, Yunnan); Nepal (Kathmandu).

Remarks. Hölzel (1973) described C. orientalis based on a female specimen from Kathmandu Valley, Nepal, and no further records of this species has been published since the original description. We examined many specimens that fit the original description of this species, especially the head without spots, the thorax without markings, the 1st rs-psm crossvein located at the end of im, etc. Here, we identify our material as C. orientalis , which represents the new record of this species from China.
