A photographic test key by Rowson & Pavett (2008) is available via the BWARS website. Else and Edwards cover Coelioxys in their new book Handbook of the Bees of the British Isles, which is due for publication soon.
Coelioxys brevis is absent from the British mainland and only found on Jersey in the Channel Islands.
In Europe, it is found from Spain, through France and across to Germany and Poland. It is also recorded from the Ukraine, Italy, Sardinia and Hungary. Further afield, it is recorded from North Africa. It has also been recorded eastwards to Iraq, India and Japan (Else, in prep.).
