New bizarre flies from mid-Cretaceous Burmese amber (Diptera, Rhagionemestriidae)

Two new genera and species referred to the extinct family Rhagionemestriidae are illustrated and described as Burminemestrinus qiyani gen. et sp. nov. and Viriosinemestrius mai gen. et sp. nov. from "mid-Cretaceous" Burmese amber. Another new genus, Cretinemestrimus gen. nov., is proposed for the Jurassinemestrinus euremus (Grimaldi, 2016) (originally Jurassinemestrinus eurema, or Jurassinemestrinus eurekus) from the same locality. Based on the new records of Rhagionemestriidae, we emended the diagnosis of the family and summarized all the fossil records and their wing vernation variation through time.
