Gonostyli with distinct rounded apical lobe and long inner process. DESCRIPTION: Body length = 2.24 mm ; wing length = 1.46 mm . Head: Eyes slightly emarginate near antennal base. Flagellum with 14 cylindrical flagellomeres, covered by trichia equal to 0.5Χ flagellomere diameter. Palpi rather long; antepenultimate segment oval, broadened; penultimate and apical segments long and slender, together equal to fore coxa in length; apical segment slightly clubbed at apex, with several short setae. Palpomere length ratio 1:2:4. Thorax: Scutum with lateral, dorsocentral, and acrostichal rows of short setae. Mediotergite bare. Wing: Veins R 1 , R 5 , M 1 , and M 2 with setae. Sc meets C before RS base. R 5 almost straight. Costa ends beyond tip of R 5 onefifth the distance between tips of R 5 and M 1 . M 1 , M 2 , and M stem weak. Base of M 3+4 absent. Legs: Hind coxae without posterior setae. Abdomen setose, with 7 visible segments, 8th one small and retracted. Gonocoxites long, stout, thinner apically. Gonostyli with rounded apical lobe, bearing dorsoventral row of bristles and long inner process, ending in a short spur. MATERIAL: Holotype PIN 3963 /4, male. Russia : Taimyr Peninsula , Bulun , coll. 1976. 3+4 ETYMOLOGY: The species epithet is toponymic. COMMENTS: Given the current low diversity of the genus, it would seem highly improbable for three fossil species to occur unless the genus was more diverse and abundant in the past.
