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