Abstract. The first part of a revision of the European species of the genus Rhabdomastix Skuse, 1890 is presented. The history of taxonomic research on Rhabdomastix is reviewed, relationships of the genus are discussed, and the subgeneric classification outlined and re-assessed. A new subgenus, Lurdia subgen. n., is established for species centred around R. lurida (Loew, 1873), and Palaeogonomyia Meunier, 1899 and Sacandaga Alexander, 1911, previously considered subgenera, are synonymized with Rhabdomastix. A revision of the European species of Lurdia subgen. n. is presented. Two species are redescribed, Rhabdomastix (Lurdia) lurida (Loew, 1873) and R. (L.) inclinata Edwards, 1938, and the lectotype of the former is designated. Descriptions are provided of seven species, viz.

New and interesting records of 60 Diptera species in ten families, namely Anisopodidae, Blephariceridae, Campichoetidae, Dixidae, Drosophilidae, Limoniidae, Lonchopteridae, Pediciidae, Psychodidae and Scatopsidae, are presented in this paper based on the specimens collected in Azerbaijan and Georgia. A total of 26 species are recorded for the first time for Transcaucasia, 32 species for Azerbaijan, and 33 species for Georgia. In addition, the first or updated checklists of the above ten families are given for these countries.

Abstract. The wing stalk in Diptera is examined, and its structures are re-evaluated and re-interpreted. The non-homology of A2 in Tipulomorpha and "A2" in other Diptera is claimed. Some notes are presented on the higher-level phylogeny of Diptera, especially those concerning Tipulomorpha. The family Trichoceridae is restored among Tipulomorpha, and the Tipulomorpha are re-affirmed as the sister group of the remaining Diptera. The clade Anisopodidae + Culicomorpha + Bibionomorpha is suggested as the sister group of Brachycera.
