| Summary: | Chironomus (Chironomus) atritibia Malloch Chironomus (Chironomus) atritibia Malloch, 1934: 16. Material examined. Lake Winnipeg light traps: 0.5 km off George Island, 1 male, 13.vii. 1969; Old Fishing Dock, 1 male, 18.viii. 1971; Calder’s Dock, 3 males, 26.viii. 1971. Of the five males caught in light traps three are intersexes. The normal male has an AR of 4.08, 7 sensilla chaetica on p2 and 6 on p3. The male intersexes have female antennae, 38–54 sensilla chaetica on p2 and 42(1) sensilla chaetica on p3. Distribution and ecology. The species was previously known from New York, Québec, Ontario, Northwest Territories, British Columbia and Washington (Townes 1945:131, Saether 1970: 7, Saether & McLean 1972: 11, Johnson & Brinkhurst 1971: 1696, Wiederholm 1976: 24, Oliver et al. 1990: 42). Martin (2012) mentions that most specimens listed by Townes (1945), other than the type, probably are C. cucini Webb. The larva is of the C. salinarius type and characteristic for mesotrophic to moderately ... : Published as part of Saether, Ole A., 2012, The Chironomus group (Diptera: Chironomidae) in Lake Winnipeg, Canada, pp. 1-19 in Zootaxa 3275 on pages 3-4, DOI: 10.5281/zenodo.280836 ... |
