ZOOSYSTEMATICA ROSSICA, 25(2): 318–332 27 DECEMBER 2016 Robber flies of the genus Trichardis (Diptera: Asilidae) of the Palaearctic Ктыри рода Trichardis (Diptera: Asilidae) Палеарктики D.M.

E-mail: [email protected] The Palaearctic species of the genus Trichardis Hermann, 1906 are reviewed. A new species, T. lehri sp. nov., is described. A new synonymy is established: T. leucocoma (van der Wulp, 1899) = T. afanasievae Lehr, 1964, syn. nov. The male of T. mongolica V. Richter, 1972 is de- scribed for the first time. External features and the male genitalia of T. lehri sp. nov., T. leuco- coma (van der Wulp, 1899) and T. mongolica V. Richter, 1972 are illustrated with photographs.
