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. R. (L.) mendli sp. n. (Switzerland, Germany, Italy), R. (L.) sublurida sp. n. (Czech Republic, Slovakia), R. (L.) furva sp. n. (Slovakia), R. (L.) loewi sp. n. (Switzerland, Germany, Austria, Italy), R. (L.) robusta sp. n. (Czech Republic, Slovakia), R. (L.) falcata sp. n. (Switzerland, Germany, Bulgaria) and R. (L.) tatrica sp. n. (Slovakia). Male and female terminalia are illustrated for all the species (except female falcata), and a key to species is appended.
The second and final part of a revision of the European species of the genus Rhabdomastix Skuse, 1890 is presented. The subgenus Rhabdomastix s. str. is revised. Seven species are redescribed, Rhabdomastix (Rhabdomastix) japonica Alexander, 1924, R. (R.) laeta (Loew, 1873), R. (R.) borealis Alexander, 1924, R. (R.) edwardsi Tjeder, 1967, R. (R.) subparva Starý, 1971, R. (R.) hirticornis (Lackschewitz, 1940) and R. (R.) beckeri (Lackschewitz, 1935). Three new synonyms are proposed. Lectotypes of four pertinent nominal species are designated. Descriptions are provided of six species, viz. R. (R.) laetoidea sp. n. (Czech Republic, Slovakia, Bulgaria, Ukraine), R. (R.) crassa sp. n. (France, Czech Republic, Slovakia), R. (R.) corax sp. n. (Bulgaria, Greece), R. (R.) eugeni sp. n. (France, Switzerland, Germany, Czech Republic, Slovakia, Italy, Romania, Bulgaria, Greece, Ukraine, Armenia), R. (R.) filata sp. n. (Bulgaria, Greece, European Russia, Turkey, Georgia, Armenia) and R. (R.) georgica sp. n. (Georgia). Male and female terminalia are illustrated for all the species, and a key to species is appended.
A review of West Palaearctic species of the genus Eloeophila Rondani, 1856 is presented. Three species are redescribed, viz. E. czernyi (Strobl in Czerny & Strobl, 1909), E. laciniata (Edwards, 1928), and E. pusilla (Kuntze, 1920). A lectotype of the latter is designated. Eloeophila albofascia (Alexander, 1975) is established as a new junior synonym of E. apicata (Loew, 1871). Descriptions are provided of E. bipartita sp. n. (North Italy), E. delmastroi sp. n. (North Italy), E. lucasi sp. n. (South Italy and Sicily), E. maroccana sp. n. (Morocco, Spain), E. martinovskyi sp. n. (South Italy), E. minor sp. n. (Czech Republic, Slovakia), E. pectinistylus sp. n. (Spain), E. punctulata sp. n. [Cyprus, Greece (Crete)], E. sparsipunctum sp. n. (Bulgaria), and E. tigricosta sp. n. (Spain). A key to males of all West Palaearctic species is presented.
