Abstract

In this faunistic survey, findings of 108 Ichneumoninae species, excluding tribe Phaeogenini, are reported from different areas of the North-Western Russia, namely Republic Karelia, Murmansk and Arkhangelsk Provinces. Among them, 5 species are reported for the territory of Russia for the first time, 48 species are new for the fauna of Republic Karelia, 12 species new for Murmansk Province, 7 species new for Arkhangelsk Province. Also the hitherto unknown male of Stenobarichneumon tegelensis (Heinrich, 1951) is described from Karelia. Ichneumon sedulus Gravenhorst, 1820 is a new synonym of Barichneumon sexalbatus (Gravenhorst, 1820) syn. nov. Barichneumon sedulus auct. nec Gravenhorst is re-named Barichneumon vicarius (Wesmael, 1845) here.

Highlights

  • Ichneumonidae is one of the largest families of hymenopterous insects and the largest family in the Fennoscandian entomofauna, e. g. the number of recorded species in Finland is more than 2500 [Koponen et al, 2009]

  • Accounted in a recent catalogue, about 1300 species of the subfamily Ichneumoninae have so far been recorded from the Western Palaearctic region [Yu et al, 2016]

  • The ichneumonine fauna of the Russian Fennoscandia has been addressed in few studies

Summary

Introduction

Ichneumonidae is one of the largest families of hymenopterous insects and the largest family in the Fennoscandian entomofauna, e. g. the number of recorded species in Finland is more than 2500 [Koponen et al, 2009]. The subfamily Ichneumoninae represents a significant group within the family Ichneumonidae, whose members usually parasitize lepidopteran larvae and pupae This group includes many large and colorful species, our knowledge of the taxonomy and distribution of Palaearctic Ichneumoninae is still incomplete, even in well studied areas such as Europe. Some records can be found in numerous faunistic articles by Wolter Hellén [1936, 1939, 1946; etc.] and some other authors [Krogerus, 1938, 1960; Kerrich, 1939; Ranin, 1979, 1981; etc.] These data are available in the papers based on collections from the territories belonging to Finland before World War II, and resulted from the treatment of the materials collected during the war from temporarily occupied territories of Russian Karelia. The level of our knowledge in this field still remains insufficient, despite of certain progress achieved lately
