Per i gonostili incurvati potrebbe essere
Andrena (Micrandrena) simontornyella Noskiewicz, 1939.

Ho visto che nel sottogenere sono importanti le proporzioni dei primi articoli antennali.
Provo a controllarli ed a fare una foto.

Ciao

La forma dei gonostili è più che sufficiente a confermare la specie, non c'è altro di simile :hi:
