First records of the ichneumonid wasp Misetus nordicator Selfa, 1995 (Hymenoptera, Ichneumonidae) outside Sweden, with the description of the male

Abstract

This study deals with the first Norwegian records of the ichneumonid wasp Misetus nordicator Selfa, 1995. 24 males and one female were recorded from 13 Norwegian localities in the period 1996–2016: i.e. Østfold [Ø] Halden: Vesttorp; Akershus [AK] Frogn: Lågøya; Oslo [AK] Oslo: Hovedøya, Ullensaker: Sessvollmoen; Buskerud [BØ] Kongsberg: Skollenborg; Telemark [TEY] Drangedal: Ronnomdalen; Aust Agder [AAY] Grimstad: Rønnes and Marivold; Hedmark [HEN] Åmot: Kildesaga; Nordland [NSI] Grane: Majavatn and Nordre Laksforsmo; Finnmark [FV] Alta: Kåfjord and Detsika; all captured in Malaise traps. These are the first findings of M. nordicator outside Sweden as well as the first records of the male worldwide. A description of the male is provided and illustrated with four figures, and a world key to the genus is given. It is clear that the genus Misetus Wesmael, 1845 contains at least two species in Norway: M. oculatus Wesmael, 1845 and M. nordicator. Both species are found scattered in Southern and Central Norway, but M. nordicator seems apparently to be the most abundant of these species, and may have a slightly more northern expansion than M. oculatus. Previous records of Misetus from Norway are listed.
