Genus: Abiskomyia Edwards Abiskomyia Edwards, 1937: 140. Type species: Abiskomyia virgo Edwards, 1937, by original designation and monotypy. Abiskomyia Edwards: Goetghebuer 1940–1950: 206; Brundin 1956: 67; Pankratova 1970: 127; Cranston et al. 1983: 156; Coffman et al. 1986: 158; Cranston et al. 1989: 174; Saether et al . 2000: 53, 113, 143; Linevich et al. 2002: 66; Makarchenko & Makarchenko 2006: 288, 489, 630; Ashe & O’Connor 2012: 109; Andersen et al. 2013: 199. Generic diagnosis (emended). Based on a new material from the Russian Far East and bordering territories, the generic diagnosis given by Cranston et al. (1983, 1989), Coffman et al. (1986) and Andersen et al. (2013) should be emended as follows: Adult male. 2.1–4.4 mm long, wing length 2.2–2.5 mm. Antenna with 13 flagellomeres, sometimes with partly reduced plume; AR c. 0.39–1.15. Eye bare or pubescent, without dorsomedial extension. Clypeus massive, with setae. Palp composed of 4–5 palpomeres, sometimes with 3 palpomeres. Scutum with lightly coloured oval area on midline posterior to middle. Acrostichals present only in lightly coloured oval area or beginning close to antepronotum and ending in light oval area; dorsocentrals, uni- to multiserial; scutellars uni- to multiserial. Anal lobe of wing rounded or rectangular, sometimes reduced; costa not extended or very slightly extended; R 1 usually without setae, sometimes with 2 setae. Hind tibia with or without tibial comb. Anal point with triangular base and long, narrow, usually parallel-sided and with bare apical part. Sternapodeme usually without oral projections, sometimes with very weak oral projections. Inferior volsella with dorsal finger-like part and ventral roundish part covered with setae. Gonostylus nearly parallel-sided or with wide basal part tapering distally, with rare exception without megaseta and crista dorsalis, with nearly straight or hooked apex. Pupa. 3.2–5.3 mm long. Frontal apotome with simple or sometimes bifid frontal setae on long cephalic tubercles. Thoracic horn c. 4–8.5 times as long as wide, tapering to pointed apex, with spinules and spines. Three dorsocentrals in group, except posterior distant dorsocentral (Dc 4); all dorsocentrals branched or sometimes D 2 and D 4 simple. Tergites IV–VI and sometimes tergite VII with anteromedian oval group of brown spines. Abdominal segments II–VII with 3 pairs of lateral setae; VIII with 0–2 pairs of lateral setae; sometimes segment VII with 2 pairs of lateral setae. Anal lobe slightly chitinized or bearing chitinized projection with rounded or triangularrounded apex without spinules and spines or with teeth, spinules and spines placed laterally in subapical part. Larva. Up to 4.5–5 mm long. Antenna with 5 segments, located on pedestal with pointed projection. Two or three ring organs on proximal 1 / 4 of basal segment, distal ring organ with long seta, proximal ring organ with shorter setae. Longest branch of blade ending near middle part of segment 4 or near apex of segment 5. Lauterborn organs large, one on apex of second segment and one on apex of third segment. Style arising in subapical part of segment 3 or sometimes absent. AR 1.50–2.14. S I plumose or palmate; labral lamella abutting sockets of S I oval or triangular, sometimes labral lamella with rounded anterior edge and small notch at midlength. Apical tooth of mandible slightly longer or equal to combined width of 3 inner teeth, sometimes apical tooth slightly shorter than combined width of 3 inner teeth. Mentum with 4 lightly coloured median teeth and 5 pairs of lateral teeth; first pair of lateral teeth yellow and smallest, located at the base of median teeth; median teeth often ground off or broken (in this case mentum with flat top); ventromental plate broad, subtriangular, covered with small spines; setae submenti branched. Pecten galearis absent or weakly developed. Procercus nearly as high as wide, bearing 7–9 apical anal setae. : Published as part of Makarchenko, Eugenyi A. & Makarchenko, Marina A., 2015, Review of the genus Abiskomyia Edwards (Diptera: Chironomidae: Orthocladiinae), with description of new taxa from the Russian Far East and bordering territories, pp. 41-60 in Zootaxa 3919 (1) on page 42, DOI: 10.11646/zootaxa.3919.1.2, http://zenodo.org/record/287874 : {"references": ["Edwards, F.
