Annotated catalogue of the bees described by Léon Provancher (Hymenoptera: Apoidea)

Abstract

AbstractThe bee species described and identified by Léon Provancher are reviewed. From 1882–1896, Provancher published accounts of 179 bee species from North America, which represent 145 currently recognised species. He proposed 67 new names, 21 of which are here considered valid; five species epithets proposed by Provancher were junior homonyms.The following are considered new junior synonyms of Provancher species:Andrena macrocephalaCockerell underAndrena nigripesProvancher;Pseudopanurgus nebrascensis(Crawford) underPseudopanurgus aestivalis(Provancher);Lasioglossum timberlakeiMcGinley underLasioglossum californicum(Provancher);Osmia kenoyeriCockerell underOsmia tarsataProvancher. Additional new synonymies made here include:Halictus distinguendusDalla Torre underLasioglossum coriaceum(Smith);Osmia parvaProvancher underOsmia atriventrisCresson;Stelis plena(Provancher) underStelis lateralisCresson;Coelioxys tristisProvancher underCoelioxys sodalisCresson;Diadasia tricinctaProvancher underEucera actuosa(Cresson).Lectotypes for 60 of Provancher's bee species are here designated, but type material for eight other species were not found. The taxonomic placement ofCalliopsis quadrilineataProvancher,Calliopsis interruptaProvancher,Hoplitis alboscopata(Provancher),Hoplitis imperfecta(Provancher), andDiadasia albovestitaProvancher within the bee fauna of North America remain unclear, and are here declarednomina oblita.
