The Ukrainian Diptera fauna is scarcely known; there are many recent studies reporting fly families new to the country (Korneyev 1997, 1999a,b, 2003, Misiachna & Korneyev 2015). The family Periscelididae is a small dipterous family with 107 extant species (Periscelididae sensu lato) (Mathis & Rung 2011).
