Background Museums and other institutions curating natural history collections (NHCs) are fundamental entities to many scientific disciplines, as they house data and reference material for varied research projects. As such, biological specimens preserved in NHCs represent accessible physical records of the living world's history. They provide useful information regarding the presence and distribution of different taxonomic groups through space and time. Despite the importance of biological museum specimens, their potential to answer scientific questions, pertinent to the necessities of our current historical context, is often under-explored. The currently-known wild bee fauna of Luxembourg comprises 341 registered species distributed amongst 38 different genera. However, specimens stored in the archives of local NHCs represent an untapped resource to update taxonomic lists, including potentially overlooked findings relevant to the development of national conservation strategies. New information We re-investigated the wild bee collection of the Zoology Department of the National Museum of Natural History Luxembourg by using morphotaxonomy and DNA barcoding. The collection revision led to the discovery of four species so far not described for the country: Andrena lagopus (Latreille, 1809), Nomada furva (Panzer, 1798), Hoplitis papaveris (Latreille, 1799) and Sphecodes majalis (Pérez, 1903). Additionally, the presence of Nomada sexfasciata (Panzer, 1799), which inexplicably had been omitted by the most current species list, can be re-confirmed. Altogether, our findings increase the number of recorded wild bee species in Luxembourg to 346. Moreover, the results highlight the crucial role of NHCs as repositories of our knowledge of the natural world.

从修订的自然历史收集数据和实地调查中推断出卢森堡野生蜂群清单的更新

背景 博物馆和其他管理自然历史收藏 (NHC) 的机构是许多科学学科的基本实体，因为它们为各种研究项目提供数据和参考材料。因此，保存在 NHC 中的生物标本代表了生物世界历史的可访问的物理记录。它们提供了有关不同分类群在空间和时间上的存在和分布的有用信息。尽管生物博物馆标本很重要，但它们回答与我们当前历史背景的必要性相关的科学问题的潜力往往未被充分探索。卢森堡目前已知的野生蜜蜂动物群包括 341 个注册物种，分布在 38 个不同的属中。然而，保存在当地 NHC 档案中的标本是更新分类清单的未开发资源，包括与制定国家保护战略相关的可能被忽视的发现。新信息 我们使用形态分类学和 DNA 条形码重新调查了卢森堡国家自然历史博物馆动物学部的野蜂收藏。收集修订导致发现了四个迄今为止未在该国描述的物种：Andrena lagopus (Latreille, 1809)、Nomada furva (Panzer, 1798)、Hoplitis papaveris (Latreille, 1799) 和 Sphecodes majalis (Pérez, 1903)。此外，可以重新确认 Nomada sexfasciata (Panzer, 1799) 的存在，莫名其妙地被最新的物种清单忽略了。共，
