ABSTRACT: Finding of larval remnants belonging to archaic Diptera from the family Nymphomyiidae in Oron lake (Irkutsk Area, Bodaibinskiy District) bottom sediments is indicated for the first time. Remains of the larval head capsules are related to the recent group of species Nymphomyia gr. rohdendorfi, distributed mostly in the Russian Far East, as well as in south-eastern Asia and North America. A brief characterization of the location and morphological description of Nymphomyiidae remnants of the larval head are given and illustrated. The approximate period of time at which Nymphomyiidae inhabited Oron lake is established.

KEY WORDS: Nymphomyia, fossils, Kodar ridge, Minor Ice Age, paleolimnology.
