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.
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.
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.
