Medetera is a large genus of flies in the family Dolichopodidae.

[11] The adults are commonly found resting on vertical surfaces such as tree trunks, on which they have a characteristic vertical upright stance.

Medetera adults are predators of soft-bodied arthropods, while the larvae are predators of bark beetle larvae.

[2][12][13] A 2011 molecular phylogenetic analysis of Medetera and related genera found that Medetera is paraphyletic with respect to Dolichophorus, and that Thrypticus is a sister taxon to Medetera + Dolichophorus.

[14] Taxonomy follows Bickel (1985, 1987),[2][12] though some of the species groups are treated as separate genera by other authors.
