Medetera Gressitti
''Medetera'' is a large genus of flies in the family Dolichopodidae. It includes about 350 species worldwide. The adults are commonly found resting on vertical surfaces such as tree trunks. The larvae are predators of bark beetle larvae. A 2011 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''. Species Taxonomy follows Bickel (1985, 1987), though some of the species groups are treated as separate genera by other authors. * ''nova'' species group: ** ''Medetera dominicensis'' Robinson, 1975 ** ''Medetera nova'' Van Duzee, 1919 ** ''Medetera xanthotricha'' Becker, 1922 ** one undescribed species from Chiapas, Mexico * ''isobellae'' species group: ** ''Medetera isobellae'' Bickel, 1985 ** ''Medetera pseudonigripes'' Robinson, 1975 * ''petulca'' species group: ** ''Medetera aeneiventris'' Van Duzee, 1933 ** ''Medetera ...
