A revised checklist and time window based province catalogue of the long-legged flies (Diptera: Dolichopodidae) of Sweden, with six new synonymies in Dolichopus Latreille, 1796

Abstract

We present an updated checklist of the family Dolichopodidae (Diptera) in Sweden based on major Swedish museum collections, private collections, newly acquired material during the Swedish Malaise Trap Project (SMTP), and literature, including a total of about 92,000 specimens. The previous checklist of 2004 included 334 species. Twenty-five of these species were removed, including 12 species without specimens in Swedish or other collections, seven species which have been synonymized since 2004, and the following six species being synonymized in the present paper: Dolichopus atritibialis Zetterstedt, 1859 = D. urbanus Meigen, 1824 syn. nov.; Dolichopus exiguus Zetterstedt, 1843 = D. arbustorum Stannius, 1831 syn. nov.; Dolichopus fulgidus Fallén, 1823 = D. campestris Meigen, 1824 syn. nov.; Dolichopus inconspicuus Zetterstedt, 1843 = D. simplex Meigen, 1824 syn. nov.; Dolichopus propinquus Zetterstedt, 1852 = D. trivialis Haliday, 1832 syn. nov. and Dolichopus spretus Loew, 1871 = D. vitripennis Meigen, 1824 syn. nov. First records of 35 species were added, raising the total number of Swedish species to 345. A time window based Swedish province catalogue is also presented, containing six time windows covering data collected before 1900 and five 25 year periods from 1900 until present. The total number of data entries i.e. unique combinations of species/province/time window is 5,768.
