Popis:	It has been shown for the first time that larvae of the genus Strongylophthalmyia Heller, 1902 (Diptera, Strongylophthalmyiidae) develop under the bark of deciduous trees: Betula sp., Populus sp., Quercus sp., Ulmus sp., Acer sp., and Maackia sp. They prefer fallen or broken trunks and inhabit partly decomposed or fresh bast near sap accumulations. The larvae are saprophloeophagous and, at the late instars, sapronecrophagous. They have branching, treelike anterior spiracles and peculiar three-lobed posterior spiracles situated in the middle of the posterior margin of the ultimate body segment. The pharyngeal sclerite has a weakly developed dorsal tubercle at the base of the ventral cornua. The morphological features of the larvae support W. Hennig’ conclusion that the genus Strongylophthalmyia should be placed in a separate family.
