This species was formerly known by the name Andrena saundersella (Perkins, 1914), now treated as a synonym of semilaevis Pérez.
The species occurs throughout much of the British Isles. In Britain it is found from the south coast of England north to the Isle of Man and northern Scotland (Easterness). It is similarly widespread in Ireland, reaching Down in the north. In the Channel Islands it has been reported from Alderney, Herm, Guernsey, Jersey (Richards, 1979) and Sark (Beavis, 2000). A common bee that is easily overlooked on account of its small size.
This is a northern and central European species, ranging from central Fennoscandia south to the Pyrenees, Yugoslavia and Ukraine (Gusenleitner & Schwarz, 2002). It is apparently absent from the Mediterranean Basin.
