Sarmitunturi near Vanhapää (Inari distr.), c. 13 km west of the Russian border, 3 June– 27 August 2004, Malaise trap, 6 males, JS. NORWAY. Kvitblik near Fauske, 7 July 2006, sweep net, 1 male, WG. Diagnostic description. Adult male (measurements in Tables 2 and 8). Colouration. Generally dark. Antennal pedicel, scutal stripes, postnotum, sternum and legs dark brown to fuscous; antennal flagellum, head capsule, scutellum, haltere, ground colour of thorax and abdomen including hypopygium olive-brown to dark brown; wing with brownish undertone, with C, M and radial veins distinctly darker, brown. Head. Antenna with 13 well separated flagellomeres. Frontal tubercles rarely present, formed as tiny swellings. Third palpomere longer than fourth. Wing. Sc, M, R 2 + 3, very short proximal section of M 1 + 2 and 1 / 3 proximal part of Cu bare, remaining veins with macrotrichia. FCu under RM. RM very short. Membrane below An with sparse macrotrichia. Anal lobe of wing strongly reduced (Fig. 2). Legs. Spur of fore tibia straight, 4–15 μm long, often reduced or absent. Combs of mid and hind tibiae slightly separated or fused, each tibia with 30–32 teeth 10–15 μm long (mid leg) and 30–35 teeth 14–16 μm long (hind leg). Hypopygium. Gonostylus long, widest in half length, subapically narrowed, tapering to blunt tip. Anal tergite with long separated bands of V-type; lateral teeth absent; anal point broad at base, very short and apically rounded, bearing thin crests; microtrichia-free area surrounding base of anal point small (Fig. 12). Superior volsella variable in shape, usually with convex and broadly rounded anteromedian margin and apex; digitus stout but short, reaching half length of superior volsella, apically rounded, variable in shape; Micropsectra -seta placed on tall cylindrical tubercle (Figs 12, 13).
