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

摘要

The 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 arehere considered valid; five species epithets proposed by Provancher were junior homonyms. The following are considered new junior synonyms of Provancher species: Andrena macrocephala Cockerell under Andrena nigripes Provancher; Pseudopanurgus nebrascensis (Crawford) under Pseudopanurgus aestivalis (Provancher); Lasioglossum timberlakei McGinley under Lasioglossum californicum (Provancher); Osmia kenoyeri Cockerell under Osmia tarsata Provancher. Additional new synonymies made here include: Halictus distinguendus Dalla Torre under Lasioglossum coriaceum (Smith); Osmia parva Provancher under Osmia atriventris Cresson; Stelis plena (Provancher) under Stelis lateralis Cresson; Coelioxys tristis Provancher under Coelioxys sodalis Cresson; Diadasia tricincta Provancher under Eucera 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 of Calliopsis quadrilineata Provancher, Calliopsis interrupta Provancher, Hoplitis alboscopata (Provancher), Hoplitis imperfecta (Provancher), and Diadasia albovestita Provancher within the bee fauna of North America remain unclear, and are here declared nomina oblita.
