Notes.

This species is widely distributed in the Holarctic region, and it has also been introduced into New Zealand ( Yu et al. 2016). Here we record the species for the first time in the High Arctic: Greenland, as well as Axel Heiberg, Baffin and Ellesmere Islands. Várkonyi and Roslin (2013) and Wirta et al. (2016) recorded it as ' Dolichogenidea sp.' from Greenland. The sequence of that specimen in BOLD (sequence code: GRAFW237-11) matches several sequences of Dolichogenidea sicaria (from Canada, Norway, Sweden and USA specimens), clearly indicating that the Greenland specimen is conspecific with them. Hosts: In the High Arctic, Várkonyi and Roslin (2013) mentioned as probably host Stenoptilia islandica (Staudinger, 1857) ( Pterophoridae ), a record we accept here as very likely based on their explanation [ Várkonyi and Roslin (2013) wrote: "On 17 July 2011, a microgastrine cocoon attached to the remains of a microlepidoptera larva was found under a tuft of Saxifraga cespitosa Linnaeus ( Saxifragaceae )>700m in the bare basalt cap area of Aucellabjerg. By 24 August 2011, a female Dolichogenidea species hatched from this sample. As S. cespitosa is the host plant of Stenoptilia islandica (Staudinger) ( Lepidoptera : Pterophoridae ) (table 3), as several specimens of this microlepidopteran species were seen and collected (exclusively) at high elevations on Aucellabjerg, and as Dolichogenidea species (like all microgastrine wasps; for the Zackenberg species see Table 1) are koinobiont endoparasitoids of Lepidoptera larvae (Shaw and Huddleston 1991), S. islandica seems a potential host of this species. Clearly, direct rearing records are needed to verify this hypothesis."]. In more southern localities, outside of the High Arctic, many other species of Lepidoptera have been cited as hosts of D. sicaria (e.g., Yu et al. 2016), with some of those records being questionable.
