Empidoidea
The Empidoidea are a large monophyletic superfamily of true flies, the sister taxon to the Muscomorpha (Cyclorrhapha). These two groups are sometimes united in the unranked taxon Eremoneura. There are some 10,000 known species within Empidoidea,Moulton & Wiegmann (2007) which are represented on all continents except Antarctica. They are known to have existed since the Jurassic period.Grimaldi & Engel (2005) Empidoidea has been subject to much debate regarding its phylogeny. Based on morphology alone, three major hypotheses had been proposed until 2007 and seemed to be consensus for some time—however, in 2018, Wahlberg & Johanson published the most current phylogeny supported by extensive genetic data, changing the relationship between quite a few families and tribes.Wahlberg & Johanson (2018) Description The majority of these insects are predatory, often with large compound eyes (sometimes covering almost the entire surface of the head), and tend to be associated with moist, t ...
