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specimens matching A. campanulae are distinct based on morphology and barcode data ( Gibbs et al. 2023 , ZP and MA, unpublished), so we are treating it as a separate species, though we have not been able to examine any males or compare to the holotype .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) .
