Andrena (incertae sedis) numida Lepeletier, 1841 and Andrena (incertae sedis) hypopolia Schmiedeknecht, 1883

Remarks. Wood (2023a) clarified the relationship between these two taxa as distinct based on morphological and genetic data. Andrena numida is found in North Africa, Sicily, and southern Italy north to Lazio, whereas A. hypopolia is widely distributed across Europe and probably Turkey into northern Italy. Both A. inconspicua Morawitz, 1871 (described from Calabria, see Astafurova et al. 2021) and A. propinqua var. syracusae Strand, 1921 (described from Sicily) were synonymised with A. numida . The exact range limits of A. hypopolia and A. numida must be clarified through additional revision of material and genetic work. To our knowledge, A. hypopolia extends south to Lazio (Rome) and Sardinia, and A. numida extends north to sandy habitats around Maccarese based on newly barcoded material. The two species therefore appear to be present more or less in sympatry, but this requires more study to confirm with certainty.
