Abstract

The oldest representatives of several cecidomyiid tribes are characterised and described from the Lower Cretaceous Lebanese amber, viz. a Lestremiinae with uncertain tribe affinities; two Winnertziinae Winnertziini: Libanoclinorrhytis jaschhofi gen. et sp. nov., and Lebanowinnertzia perrichoti gen. et sp. nov.; and two Porricondylinae Dicerurini: Cretadicerura salimi gen. et sp. nov. and Libanohilversidia doryi gen. et sp. nov. These taxa are the oldest representatives of their respective tribes.
