Primary Literature, keys to Andrena species
Having
ascertained the Andrena subgenus, the next step would be to consult the species
keys in the publications of W.E. LaBerge, and various collaborators. These are
challenging for the non-specialist, with technical language and references to
material most users will not have at hand. Particularly frustrating is the lack
of any kind of illustration that might explain ambiguous characters. But at
present (to my knowledge), these are the definitive resources.
Oh, and:
most of these are behind paywalls, in many cases set to become freely available
after 2050. In the meantime, the taxa will likely be revised by others to
incorporate more accurate phylogeny, and hopefully more accessible ID tools.
The best of which might be the era of cheap and rapid barcoding.
For now,
we have:
