The inclusion of this bee on the British list rests on a female in the F. Smith Collection in the University Museum, Oxford. The only documentation carried on the pin is “16.8.”. According to R.C.L. Perkins (1914) the specimen was probably sent to Smith by J.B. Bridgman of Norwich as the pin, mode of setting and label is similar to that of other Andrena known to have been sent by him to Smith in the period 1875-77. The numerals “16.8” presumably indicates the date. This specimen is not mapped.
This is a very rare, local and little known bee though widely distributed throughout much of Eurasia, from Sweden to France and Italy, east to the far east of the Russian Federation (Dylewska, 1987; Gusenleitner & Schwarz, 2002; Ascher & Pickering, 2012).
