Contributions to the study of the Holarctic fauna of Microgastrinae (Hymenoptera, Braconidae). I. Introduction and first results of transatlantic comparisons

Abstract

Specimens of Microgastrinae (Hymenoptera: Braconidae) from both sides of the Holarctic region (Nearctic and Palaearctic) were sampled for DNA barcoding and examined morphologically. Two species are recorded for the first time for the Nearctic: Apanteles brunnistigma Abdinbekova, and Microgaster raschkiellae Shaw. Another European species, Apanteles xanthostigma (Haliday), previously introduced as a biological control agent, is confirmed to be present in North America. For another 13 species significant range extension is documented, including new records for France, Canada, United States, and Sweden. New host data are also provided for several species. The species name Apanteles masmithi Fernandez-Triana is considered a syn. n. of Dolichogenidea britannica (Wilkinson). Copyright Jose Fernandez-Triana et al.
