Comments: This morphospecies ( Figure 6 ) had previously been included under the Andrena geranii complex by ZP due to the reduced propodeal corbicula, but it appears to match the description of the Andrena aff. nigrihirta reported recently from Manitoba in Gibbs et al. (2023) based in part on the curved tibial spurs. However, the apparent association between this species and Uvularia in Minnesota raises the possibility that this is not the same species as the one reported in Gibbs et al (2023) , since Uvularia is not widespread in Manitoba . Additional investigation is needed and the subgenus Ptilandrena is in need of revision.
