Added note: The correct subgenus is no longer Mesoxaea (Heteroxaea). It is Mesoxaea (Mesoxaea). Bossert S., et al. (2022) Phylogeny, biogeography and diversification of the mining bee family Andrenidae. Systematic Entomology 47(2):283–302. [“Since the diagnosis of the subgenus Heteroxaea is almost exclusively based on pile colouration (Engel, 2015), we regard the subgenus Heteroxaea as a junior synonym of Mesoxaea.” at p. 290.] The PDF is available here: https://entomology.wsu.edu/directory/faculty/silas-bossert/
