Contribution to bee fauna (Hymenoptera: Apoidea: Anthophila) of Poland. VII. The genus Andrena Fabricius, 1775. Part 3

The paper presents information about the following eight, either exceedingly rare or infrequently recorded species of short-tongued bees of the genus Andrena Fabricius, 1775 in Poland: A. (Lepidandrena) florivaga Eversmann, 1852; A. (Lepidandrena) rufizona Imhoff, 1834; A. (Melandrena) gallica Schmiedeknecht, 1883; A. (Micrandrena) enslinella Stoeckhert, 1924; A. (Micrandrena) nana (Kirby, 1802); A. (Micrandrena) nanula Nylander, 1848; A. (Micrandrena) pusilla Perez, 1903; A. (Micrandrena) saxonica Stoeckhert, 1935. This is the third contribution concerning the rare species of the genus Andrena Fabricius, 1775 in Poland. The studies were conducted from 2010 to 2019, and ca. 24,000 specimens from both the museum and private collections of bees of the genus Andrena from Poland were identified. Currently, the Polish fauna has 96 taxa of mining bees of the genus Andrena. For each species, the following information is provided: short diagnosis, remarks on general distribution, bionomics, published records from Poland and confirmed Polish records based on studied collections, as well as current category of threat resulted from the studies.
