Abstract

AbstractFive new species, Apometriocnemus beringensis, Cricotopus (Cricotopus) bifurcatus, Doithrix dillonae, Hydrobaenus piloculus, and Paratrissocladius lawrencensis, are described. The following new combinations are established: Bryophaenocladius astis (Roback 1951b); Compterosmittia nerius (Curran 1930); Parakiefferiella subaterrima (Malloch 1915); Paratrichocladius nitidus (Malloch 1915); Pseudosmittia nanseni (Kieffer 1926); and Zalutschia sivertseni (Aagard 1979). New genus name synonymies are Maricladius Sublette, 1970 with Parakiefferiella Thienemann, 1936; and Prosmittia Brundin, 1956 with Pseudosmittia Goetghebuer, 1932. New species name synonymies are Spaniotoma (Trichocladius) senex Johannsen, 1937 with Trichocladius nitidellus Malloch, 1915 (= Acricotopus nitidellus); Hydrobaenus traenis Roback, 1957b with Hydrobaenus astis Roback, 1957b (= Bryophaenocladius astis); Compterosmittia clavigera Saether, 1982 with Camptocladius nerius Curran, 1930 (= Compterosmittia nerius); Cricotopus flannagani Saether, 1971 with Cricotopus macraei Saether, 1971; Gymnometriocnemus marionensis Saether, 1969 with Metriocnemus subnudus Edwards, 1929 (= Gymnometriocnemus (Gymnometriocnemus) subnudus); Gymnometriocnemus (Raphidocladius) acigus Saether, 1983 with Metriocnemus brumalis Edwards, 1929 (= Gymnometriocnemus (Raphidocladius) brumalis); Limnophyes spatulosus Saether, 1975 with Limnophyes borealis Goetghebuer, 1933; Limnophyes cristatissimus Saether, 1975 with Camptocladius fumosus Johannsen, 1905 (= Limnophyes fumosus); Limnophyes hudsoni Saether, 1975 with Limnophyes immucronatus Saether, 1969; Hydrobaenus hudsoni Saether, 1977 with Chaetocladius (Parachaetocladius) abnobaeus Wülker, 1959 (= Parachaetocladius abnobaeus); Parakiefferiella torulata Saether, 1969 with Camptocladius subaterrimus Malloch, 1915 (= Parakiefferiella subaterrima); Trichocladius helis Roback, 1957b with Orthocladius nitidus Malloch, 1915 (= Paratrichocladius nitidus); Syncricotopus fontinalis Saether, 1969 with Chironomus rufiventris Meigen, 1830 (= Paratrichocladius rufiventris); Pseudorthocladius (Lordella) comans Saether and Sublette, 1983 with Pseudorthocladius (Lordella) wingoi Saether and Sublette, 1983; Smittia triappendiculata Goetghebuer, 1931 with Camptocladius forcipatus Goetghebuer, 1921 (= Pseudosmittia forcipatus); and Psilometriocnemus cristatus Saether, 1982 with Psilometriocnemus triannulatus Saether, 1969. Major new distribution records are given for 49 species including 8 Nearctic and 32 Canadian. A key to adult males of Nearctic Limnophyes is given.
