1.    Mydaea emeishanna sp. nov. (Fig.1) ♂: Body length 6.5 mm. 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; 29º44’N, 103º31’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 mrgins round. ♀: Unknown.

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; abdoment dark and without shifting spots. ♀: Unknown.
