Andrena nana (Kirby, 1802)

Description and notes

It should be noted that the name Andrena nana has occasionally been misapplied in the older literature (e.g. Smith, 1855; Saunders, 1896) and in some collections, being a misidentification for A. semilaevis Pérez.

Distribution

This species is known in Britain from just five records: East Suffolk, Barham (Kirby, 1802), female, the type of the species, collected pre-1802; West Suffolk, Sudbury, 1923, female, B.S. Harwood (Perkins, 1924) (in Natural History Museum, London); West Kent, Luddesdown, 27th August 1899, female, H. Elgar (Felton, 1963) (in Maidstone Museum); West Kent, Eynesford, 27th April, 1930, male (in Natural History Museum, London) and Surrey, Oxshott, July 1915, male, collector not known (in Oxford University Museum). As the most recent record was made more than eighty years ago, it is highly likely that the species is now lost from the British fauna.

This is a Western Palaearctic species, distributed from Sweden and Estonia to Spain, east to Sardinia, Italy, Ukraine and Kazakhstan. Also known from North Africa (Morocco to Tunisia) (Osytshnjuk, 1977; Gusenleitner & Schwarz, 2002; Ascher & Pickering, 2012).
