| Summary: | Key to male Rhamphomyia of the Canadian Arctic Islands, Greenland and Iceland 1 Prosternum clothed entirely with white to brownish silky, hair-like setae (Fig. 3D); sternite 6 with cluster of strong golden setae; sternite 7 with pair of horn-like projections ventrally (Fig. 3C). R. (Ctenempis) albopilosa Coquillett - Prosternum bare; sternite 6 without row of golden setae; sternite 7 unmodified or modified different than above. 2 2 Cerci directed anteriorly (Figs 6A, 9C, 12B, 15B) (subgenus Dasyrhamphomyia). 3 - Cerci directed posteriorly. 6 3 Thorax short haired (setae shorter than gaps between rows) with acrostichals and dorsocentrals 1–2 serial, with brown vittae beneath rows; cerci with dark apex, with left cercus overlapping right at tip (Figs 12B, C); hind tibia with anteroventral row of dark, stout, spine-like setae shorter than half tibial width. R. (D.) leptidiformis Frey - Thorax long haired (setae longer than gaps between rows) with acrostichals and dorsocentrals 2–4 serial, without brown vittae beneath rows; cerci not darkened at apex, with right cercus overlapping left at tip (Figs 9D, 15C); hind tibia without anteroventral row of dark, stout, spine-like setae. 4 4 Cerci pale, elongate, extending to tergite 3, overlapping subapically in addition to apical overlap (Figs 15B, C). R. (D.) nigrita Zetterstedt - Cerci brownish to black, shorter, extending to tergite 5, only overlapping apically (Figs 6A, 9C). 5 5 Dichoptic; abdomen with setae longer than length of abdominal tergites; cerci blackish (Fig. 6A); hind tibia and femur with pronounced fine, pale ventral pubescence (Fig. 6C). R. (D.) erinacioides Malloch - Holoptic; abdomen with setae shorter than length of abdominal tergites; cerci pale brown (Fig. 9C); hind tibia and femur with long setae beneath (Fig. 9A). R. (D.) hovgaardii Holmgren 6 Wing without dm-m crossvein (cell dm open) (Fig. 62C); scutum with shiny vittae. R. (Pararhamphomyia) diversipennis Becker - Wing with dm-m crossvein (cell dm closed), sometimes dm-m crossvein or M 2 base ... |
