Material studied:

SWEDEN. 1♀, Lu. Jokkmokk, Vuollerim, Bomyrberget, in forest 135 m.a.s.l., Malaise trap, 16.-18.VIII.2006 (K. Hedmark leg.) [IZBE, mounted from alcohol]; 1♀, Lu. Jokkmokk, Vuollerim, Bomyrberget, 135 m.a.s.l., Malaise trap, 18.-24.VIII.2007 (K. Hedmark leg.) [MZLU, in alcohol]. FINLAND. 1♂, Kn. Sotkamo, Urpovaara, window trap N2, 26.VIII.-11.IX.1997 (M. Kuussaari leg.) [IZBE, on pin].

Diagnostic characters.

Female. Thorax blackish, abdomen brown. Legs yellow, cx3 with small dark markings basally. All trochanters yellow, with small black apicoventral spots. Tibiae with dense brown setae. Scape and pedicel dark yellow, first flagellomere basally yellowish, rest of flagellum brown. Mouthparts pale yellow. Apical palpal segment 1.4-1.6 (n=2) times as long as penultimate segment. Wing with narrow preapical brownish band, gradually tapering towards hind margin. C terminating almost at apex of wing, R5 distinctly arched (Fig. 9). Medial and cubital veins both reach wing margin, CuA1 basally obsolete, brownish shade along posterior margin of CuA2. Terminalia brown, cercus one-segmented, yellow apically. Tergite IX larger than tergite VIII. Gonapophysis IX visible in lateral view, with wide pear-shaped medial incision apically. Sternite VIII deeply incised apicomedially and moderately emarginated basally.

Male. Coloration and other non-terminal characters including palpi similar to female. Apical palpal segment is 1.4 (n=1) times as long as penultimate segment.

Remarks.

Zaitzev (1994) described this species from Siberian material (Buryat Republic). Subsequently only a few specimens have been recorded from Norway, Sweden, Finland and Russian Karelia (cf. Kjærandsen et al. 2007; Fig. 29). Zaitzev (1994) figured the male terminalia whereas the female terminalia have not been figured earlier. Using the key by Zaitzev (1994) the studied females run to Greenomyia baikalica and they are also morphologically conspecific with material of both sexes collected simultaneously in Russian Karelia (A. Polevoi, pers. comm.). The studied female specimens were collected in a boggy forest stand within a small (9 ha) protected remnant of semi-natural, mixed forest.
