This work presents the results obtained after a revision of the current species of the subgenus Andrena (Micrandrena) Ashmead, 1899 that appear in the Iberian Peninsula. It provides a key to the species, diagnosis, biological data, and comments about the 19 species and 5 subspecies. Additionally, it includes a redescription of five species because their original descriptions were inadequate. Newly reported for the Iberian Peninsula are Andrena floricola Eversmann, 1852 and Andrena strohmella Stöckhert, 1928. This study is the first contribution to resolve certain taxonomic problems in the subgenus Andrena (Micrandrena); however, the use of additional tools like morphometric and molecular characters are recommended in the future to confirm the taxonomic status of Andrena spreta Pérez, 1895.

With about 1700 described species, the mining bee genus is a rapidly diversifying lineage and one of the most species-rich groups of bees. Recent phylogenomic advances have greatly improved our understanding of the phylogeny of the genus, yet many species still await description, subgeneric assignments that are in line with their evolutionary history, as well as study of their morphology and behavior. Here we provide a comprehensive account of a newly discovered species, n.

The genus Andrena is principally distributed through the Holarctic, but it remains understudied in Asia. The subgenus Cnemidandrena Hedicke, 1933 is distributed across Asia with some species reaching south to the Tibetan Plateau.

Using wild pollinators to pollinate crops without introducing human-managed pollinators is cost-effective and friendly to native ecosystems. To maintain stable, good-quality yields in crops that mainly use wild pollinators, it is essential to determine which flower visitors are important pollinators and their degree of importance. In this study, we observed flower-visiting insects for 5 years in outdoor cultivated strawberries surrounded by a semi-natural environment in central Japan.

All three hitherto described species of the Palearctic subgenus Andrena (Longandrena Osytshnjuk, 1993), are revised and redescribed. This subgenus is characterized by an unusually long glossa, a rare character among short-tongued bees. A revised diagnosis of this subgenus is given.
