• Description: Anthomyza gilviventris Roh & aacute;& ccaron;ek & Barber, 2016, hitherto known only from the Nearctic Region, is recorded from the Palaearctic Region (NE Sweden) for the fi rst time. Specimens from the Swedish population have been compared with those of A. gilviventris from Canada and the USA and those of A. tschirnhausi Roh & aacute;& ccaron;ek, 2009 from the Kamchatka Peninsula (Far East of Russia). Both morphological and molecular analyses (BI and RAxML, based on seven DNA markers: 12S, 16S, 28S, COI, COII, CytB, ITS2) confi rmed that the Swedish specimens belong to A. gilviventris. Because no specimen of A. tschirnhausi has been available for molecular study, the most diagnostic morphological characters used for separation of this species from A. gilviventris have been re-evaluated with respect to Swedish specimens, and their variability discussed. However, these diff erences, although stable, are relatively small and, consequently, the possibility that they fall within the limits of a single variable species has not been entirely eliminated. New biological information (habitat and host-plant associations) on the Swedish population of A. gilviventris is presented.
