The list of 2283 Lithuanian Diptera species of 78 families is based on 224 literary sources.

12 fossil Ormosia Rondani species are discussed, and identification keys are given. Ormosia (Oreophila) abava sp. n., O. (O.) divina sp. n., O. (O.) divulgata sp. n., O. (O.) illibata sp. n., O. (O.) longipalpa, O. (O.) jurate sp. n., O. (O.) indago sp. n. and O. (Ormosia) innata sp. n. from the Baltic amber (Eocene) are described as new species, their affinities to other recent and fossil Ormosia are discussed. O. beurleni Alexander, O. electrella Alexander, O. skwarrae Alexander and O. tornquisti Alexander are redescribed on the basis of new material and ascribed to the subgenus Oreophila. It is shown that from comparatively abundant material on O. divina sp. n. and from comparison of O. beurleni Alexander with O. jurate sp. n. it is possible to determine how separate species and their features have changed in time as the fossilisation of Baltic amber has lasted few millions years. All fossil species are divided into subgenera Oreophila and Ormosia s. str., but special status of O. beurleni Alexander, O. jurate sp. n. and especially O. longipalpa sp. n. is shown. Most fossil species of Ormosia belong to subgenus Oreolata, meanwhile, subgenus Ormosia s. str. includes more than 80% of the recent Ormosia s. l. species.

A new species of short-palped crane fly, Antocha (Antocha) chonsaniana, is described from specimens collected in 1940 at Chonsani, North Korea and preserved in the Smithsonian Institution, U.S.A. Descriptions and illustrations of the distinguishing morphological features, particularly wing and male genitalic characters, are provided.
