The males of Pselliophora guangxiensis Yang Yang, 1988 and Holorusia basiflava Yang Yang, 1993 and female of Pselliophora xanthopimplina Enderlein, 1921 are redescribed and illustrated with new morphological characters. The females of P. guangxiensis and H. basiflava are described and illustrated for the first time. A key for separating known species of Indotipula Edwards, 1931 from China is provided. DNA barcodes of all species in this study are provided and analyzed.展开更多
