ABSTRACT. A key to genera of larva of the fungus gnats subfamily Sciophilinae (Diptera, Mycetophilidae) of Russia and adjacent countries is composed. Sciophilinae larvae differ from larvae of other subfamilies in the presence of long maxillary palpus.
The representatives of the genera Leptomorphus Curtis, 1831 and Phthinia Winnertz, 1863 differ from the larvae of Monoclona Mik, 1886 and Sciophila Meigen, 1818 in the open structure of head capsule: epicranial sclerites separated at ventral side however they contact at significant distance in the second group of genera. Larvae of Leptomorphus differ from Phthinia in posteriorly broaded head capsule, short maxillary palpus and divergating epicranial sclerites on ventral side. Larvae of Phthinia have uniform head capsula, epicranial sclerites are parallel at significant distance and maxillary palpus long, slightly projecting above anterior margin of the head. Sciophila larvae differ from Monoclona in the following characters: head capsule elongate-oval, slightly broaded posteriorly, epicranial plates contact at the anterior third then divergent bordering membranous area of oval form. Monoclona larvae have round-oval head capsule narrowed anteriorly, epicranial plates contact at the anterior half then diverge and converge posteriorly. Membranous area bordered by them is round. The characters for subfamily and genera are discussed.
