Drymeia cristata sp. nov. Figs. 5 A–H Diagnosis. The species is similar to D. cantabrigensis (Huckett, 1965) and D. setibasis (Huckett, 1965). Males of the new species can be distinguished as follows: anepimeron and katepimeron bare; eye bare; facial edge projecting forward beyond the level of profrons; arista swollen in basal third; proboscis elongated; anteroventral surface of mid femur with a comb of long, strong, inclined setae on middle part; hind femur without posteroventrals; hind tibia without a ventral apical prong and with only a strong anteroventral preapical seta. Etymology. The species name is based on the Latin adjective “cristatus” what means “with a comb”. Type material examined. Holotype male, RUSSIA: Krasnoyarsky Krai, Taymyr Peninsula, 90 km NW Khatanga, valley of Zakharova-Rasokha River (left tributary of Novaya River), 72.7ºN 101.08ºE, 3.vii.2011, A. Barkalov (SZMN). Paratypes: 30 males, same data as holotype, 2–16.vii.2011, A. Barkalov & V. Zinchenko (2 males each in ZIN, ZMUM, OUMNH, BMNH, BUIC). 1 male, Chukotka Autonomous Okrug, Wrangel Island, environs of Tundrovaya Mt., 18.vii.1972, K. Gorodkov (ZIN). Description. MALE. Length of body, 4.6–6.3 mm. Length of wing, 4.0– 4.6 mm. Head : Ground-colour black. Eye bare. Fronto-orbital plate and parafacial silvery-grey pruinose; face grey, gena and lower occiput grey pruinose. Fronto-orbital plates touching. Frons at narrowest point 1.5 times as wide as diameter of anterior ocellus. Ocellar setae very short. 11–13 pairs of frontal setae, including interstitials, reaching almost to anterior ocellus. Antenna black, postpedicel about as long as wide. Arista bare, swollen in basal third. Parafacial at level of insertion of arista equal to or slightly narrower than width of postpedicel, hardly narrowing below. Upper part of face without a small knob or carina between antennal bases. In lateral view, facial edge projecting forward beyond the level of profrons. Gena broad, depth below lowest eye-margin equal to length of postpedicel, densely ...
