Sur la présence en France d’Andrena confinis Stöckert, 1930, et d’Osmia bidentata Morawitz, 1876 (Hymenoptera, Andrenidae, Megachilidae)

Abstract

On the presence in France of Andrena confinis Stöckert, 1930, and Osmia bidentata Morawitz, 1876 (Hymenoptera, Andrenidae, Megachilidae). Andrena confinis Stöckhert, 1930, and Osmia bidentata Morawitz, 1876, are two wild bee species for which presence in France is dubious. Some French specimens were found in the collections of the Muséum national d’Histoire naturelle (Paris), so affiliation of these two species to the French fauna is confirmed. Major diagnostic features, ecology and distribution are provided.

Unexpected levels of cryptic diversity in European bees of the genus Andrena subgenus Taeniandrena (Hymenoptera, Andrenidae): implications for conservation

“…Obtaining accurate taxonomic and distribution information on bees is crucial for the conservation and monitoring of native pollinators. However, new species are regularly uncovered even in regions with a long tradition in taxonomy such as northern and central Europe, following changes in taxonomy (e. g., Straka and Bogusch 2011;Pauly et al 2019;Le Divelec 2020;Litman et al 2021), the discovery of hitherto undetected taxa due to challenging identifications (e. g., Notton and Norman 2017;Falk et al 2019), inventories in poorly sampled habitats (Johansson and Paukkunen 2017;Schmid-Egger et al 2021), range expansions (Notton et al 2016;Saure and Petrischak 2020), or the description of new species (e. g., Pauly et al 2015;Praz et al 2019). These recent updates in northern or central European countries, characterised by well-known faunas that are studied by numerous active bee specialists, give a worrisome hint at the huge taxonomic work necessary in southern European countries, which have rich but poorly investigated bee faunas.…”

Revisions to the faunas of Andrena of the Iberian Peninsula and Morocco with the descriptions of four new species (Hymenoptera: Andrenidae)

“…This species pair is in need of molecular revision across Europe because of historical synonymy with A. congruens Schmiedeknecht, 1884 (e.g., Warncke 1967). Both species are present in central Europe (Schmid-Egger & Scheuchl 1997;Le Divelec 2020), and material examined from northern Europe (Belgium, northern France, United Kingdom) conforms to A. confinis, suggesting that it is the more northerly of the two. Currently, only A. congruens is listed for Spain (Ortiz-Sánchez 2011), but both…”
