Closely related to Mydaea minor Ma et Wu, 1986, but differs from the latter in: Arista long plumose, the longest aristal hairs about twice as long as the width of 3rd antennal segment ; stpl 2:2 ; hind femur without pv bristle; cerci of male slightly straight and flat on distal margin in caudal view. ♀:Unknown. Holotype:♂,Mt. Emei (Hongchunping, 1120 m; 29°44'N, 103°31'E),Sichuan Province, May 20,1984, taken by Deng An xiao. 2. Mydaea jubiventera sp.nov. (Fig.2) ♂:Body length 6.0 mm. Closely related to Mydaea laxidetrita Xue et Wang,1992 from Shanxi Province, but differs from the latter in: Arista short plumose, the longest aristal hairs about one third as long as the width of 3rd antennal segment; hind femur devoid of pv bristle; surstyli of male straight on apical part in lateral view; cerci on distal margins round.♀:Unknown. Holotype ♂,Maowen (Sanlong, 2800 m; 31°42'N,103°52'E),Sichuan Province, Sept. 9, 1989, taken by Deng An xiao. 3. Mydaea jiuzhaigouensis sp.nov. (Fig.3) ♂:Body length 70 mm.

It is also closely related to Mydaea electa (Zett.,1860), but differs from the latter in: 3rd antennal segment about 3.5 times as long as broad; femora dark to black; abdomen dark and without shifting spots. ♀: Unknown.
