Andrena (Ptilandrena) cf. campanulae Viereck and Cockerell, 1914

Counties: Becker, Mahnomen, Pennington

Comments: Andrena campanulae was synonymized under A. geranii by LaBerge (1977). However, specimens matching A. campanulae are distinct based on morphology and barcode data ( Gibbs et al. 2023, ZP and MA, unpublished), so we are treating it as a separate species, though we have not been able to examine any males or compare to the holotype. Females of A. cf. campanulae are similar to A. geranii , but they have the clypeus more regularly punctured, the abdomen is black rather than slightly metallic blue, and there is a weak posterior fringe on the propodeal corbicula ( Figure 5 ). This species was previously reported from Minnesota as “ Andrena (Euandrena) n. sp. aff. geranii ” in Lane et al. (2022).
