ABSTRACT. A key to genera of larva of the fungus gnats subfamily Mycomyinae (Diptera, Mycetophilidae) of Russia and adjacent countries is composed. Mycomyinae larvae differ from larvae of other subfamilies in the structure of ventral surface of head capsule: ventral plates contact at a long distance then divergent and then connect with the help of narrow band-like sclerotized median projections. Mandibles are semicircle and broad. Mycomya Rondani, 1856 larvae differ from Neoempheria Osten-Sacken, 1863 larvae in the following characters: frontal sutures reach the end of the head capsule, posterior margin of labrum often with pointed tubercles, premandibles with 1 (not 2) apical branches, internal dents of mandibles pointed and placed in 1–2 rows. The characters for subfamily and genera are discussed.
