Revision of the historical type collections of long-horn bees (Hymenoptera: Apidae: Eucerini) preserved in the Muséum national d'Histoire naturelle, Paris

Summary. This work presents a first taxonomic revision of the historical type collections West Palaearctic bees in tribe Eucerini (Apidae) that are preserved Muséum national d'Histoire naturelle, Paris. A total 72 species names revised, 147 specimens recognised, and 33 synonyms newly proposed. Unexpectedly, some oldest bee were found to be misinterpreted have been incorrectly used for period nearly 200 years, demonstrating substantial lack knowledge. Actions taken settle taxonomy these many other species, which continuously being biodiversity studies databases. The following changes proposed: Tetralonia Spinola, 1838 is reestablished as valid genus not subgenus Eucera Scopoli, 1770 (based on F. Freitas, litt.) (stat. rev.); speculifera Pérez, 1910 n. syn. aeolopus 1910; conspersa 1895 algira Lepeletier, 1841; dentipes Saunders, 1908 atroalba brachycera Gribodo, 1893 [Eucera (Synhalonia) (Gribodo)]; wahrmani Benoist, 1950 cinnamomea Alfken, 1935; fasciatella 1841 clypeata Erichson, 1835; decolorata 1924 confinis 1895; bolivari Dusmet y Alonso, 1926 mucida cuniculina Klug, 1845; fulvescens Walker, 1871 (and its replacement name E. aegyptiaca Dalla Torre, 1896) dimidiata Brullé, 1832; gracilipes duplicata 1926) furfurea Vachal, 1907; bicolor (as well algeriensis hispana ephippia Dours, 1873 hispaliensis 1902 Apis longicornis Linnaeus, 1758 (Linnaeus)]; fallax subvillosa nigra contigua 1928 nigrifacies lucasi (Gribodo)] Macrocera obscura 1832 (Brullé)]; grisea var. effasciata Alfken oraniensis aciculata polita bipartita proxima Morawitz, 1875; sulamita 1907 syriaca 1896; kervillei maxima Tkalců, 1987 taurea obsoleta terminata also latter’s xanthura 1895); unicincta vidua carbonaria atrata 1845 [Tetralonia (Klug)]. In addition, eucnemidea confirmed synonym, formally synonymised with Fabricius, 1793 (n. syn.). species-group synonymised, despite having precedency, under principle stability: trivittata bidentata 1887; distincta pollinosa Smith, 1854; alternans (Brullé)] rufa (Lepeletier)]; subfasciata taurica 1871. impressiventris stat. rev. resurrected from synonymy punctatissima 1895, species. addition 43 lectotypes, neotypes designated two coangustata 1873, T. (syn. commixta Torre & Friese, 1895).
