Remarks

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

taxa are present in mountainous parts of northern Spain, though given the limited material available it is difficult to come to firm conclusions concerning their true distributions.

Distribution

The distribution of A. confinis is unclear because of continued confusion and synonymy with Andrena congruens Schmiedeknecht, 1884 . At this moment, it is not possible to give an accurate picture of its true distribution, but both species are present in central Europe, with A. congruens having more southern and A. confinis more northern tendencies ( Schmid-Egger & Scheuchl 1997).
