Abstract
New records of Anthomyzidae (Diptera) from the Iturup Island (Kuril archipelago, Far Eastern Russia) are presented based on the material collected by the expedition to this island in 2011. Five species of Anthomyza are recorded, including three species new to the local dipterous fauna, viz. A. collini Andersson, 1976, A. elbergi Andersson, 1976 and A. flavosterna Sueyoshi & Roháček, 2003; moreover, A. collini is recorded from the E. Palaearctic region for the first time. Distribution and biology are reviewed for each of the seven species of Anthomyzidae known from the Iturup I. with the new information obtained. Biodiversity of Anthomyzidae in the Iturup I. is discussed with respect to the faunas known from adjacent areas.
