MATERIAL. Kotelnyi, 2.VIII 2017, 1 ♂, A. Protopopov [ FRIP] .

DISTRIBUTION. Described and so far only known from Canada ( Zaitzev, 1982). It is first record from Yakutia , Russia and the Palaearctic Region. DNA data and new record may suggest wider circumpolar distribution.

REMARKS. Assigned to BIN BOLD:ACR5851 along with unidentified Sciophila from Canada (Yukon Territory) and another specimen in private record, with distance 5.63% to the nearest BIN BOLD:ACR6891, containing unidentified Sciophila from Canada. The structure of male terminalia agrees well with figures by Zaitzev (1982: Fig. 5 : 3, 4). The availability of genetically similar specimen from a place quite near one of the paratype’s locality (Herschel Island) leaves no doubt about species identity. Here we illustrate additional details of male terminalia ( Figs 2–7 ) not figured in the original description.
