SUMMARY
Mixogaster is a group of petiolate Microdon flies restricted to the New World. They are distinguished from all other petiolate Microdon groups by 1) lacking an appendix on vein R4+5; 2) having a reduced and bare metasternum; 3) unarmed scutellum; and 4) usually an appendix on vein M extending in cell R4+5. Some earlier authors more broadly interpreted the concept of this genus and described species now placed elsewhere [aphritina Thomson = Paramixogaster, bellula Williston = Pseudomicrodon, cinctella Sack = Paramicrodon, claripennis Hine = Pseudomicrodon, nigripennis Sack = Paramicrodon, variegata Sack = Paramixogaster, and vespiformis Brunetti = Paramixogaster] (Cheng and Thompson 2008). Hull (1954) provided a revision of the genus.
