ABSTRACT. The fossil record of Triassic Culicomorpha is extremely poor, with the oldest member of the infraorder having been described, as Chironomoidea incertae familiae, from the the ‘Grиs а Voltzia‘ Formation (Upper Buntsandstein, early Anisian, France). In this paper, the oldest member of another superfamily, Culicoidea, is described from the Madygen Formation (Ladinian–Carnian, Kyrgyzstan) based on an isolated wing. The new genus, Triassomyia, gen.n., is assigned to the family Chaoboridae.

KEY WORDS: Culicomorpha, fossil insects, new taxa, Triassic, wing venation.
