ABSTRACT. A more precise definition of the genus Tachypeza Meigen, 1830 (Diptera: Hybotidae: Tachydromiinae) is discussed. It is suggested to transfer to Tachypeza the following 13 species assigned earlier to the genus Tachydromia Meigen, 1803: Tachypeza annamensis (Grootaert et Shamshev, 2009), comb.n.; T. australiensis (Grootaert et Shamshev, 2011), comb.n.; T. bickeli (Grootaert et Shamshev, 2011), comb.n.; T. corticola (Grootaert et Shamshev, 2011), comb.n.; T. luang (Shamshev et Grootaert, 2005), comb.n.; T. malaysiensis (Shamshev et Grootaert, 2009), comb.n.; T. nowendociensis (Grootaert et Shamshev, 2011), comb.n.; T. ocellata (Shamshev et Grootaert, 2008), comb.n.; T. pahangiensis (Shamshev et Grootaert, 2009), comb.n.; T. phanensis (Shamshev et Grootaert, 2008), comb.n.; T. phu (Shamshev et Grootaert, 2008), comb.n.; T. sachem (Melander, 1928), comb.n.; T. stuckenbergi (Shamshev et Grootaert, 2010), comb.n.; T. tigeri (Shamshev et Grootaert, 2008), comb.n. A new species of Tachypeza, T. cummingi sp.n., is described from Canada and the USA. Currently, Tachypeza includes 45 species and the genus is formally recorded for the first time from Australasian (5 species), Afrotropical (1 species) and Neotropical (1 species) Realms. Main phylogenetic lineages within Tachypeza are provisionally discussed. A check-list of Tachypeza of the world is provided. Genera Ariasella Gil, 1923, syn.n., and Pieltainia Arias, 1919, syn.n., are placed in synonymy to Tachydromia, with the following new combinations: Tachydromia iberica (Arias, 1919), comb.n.; T. lusitanica (Grootaert, Shamshev et Andrade, 2009), comb.n.; T. pandellei (Sйguy, 1941), comb.n.; T. pieltaini (Gil, 1936), comb.n.; T. semiaptera (Gil, 1923), comb.n. Currently, the genus Tachydromia includes 108 species. Main phylogenetic lineages within Tachydromia are provisionally discussed, with two newly recognised groups of species.

KEY WORDS. Diptera, Hybotidae, Tachydromia, Tachypeza, Ariasella, Pieltainia, synonyms, new species.
