A photographic test key by Rowson and Pavett 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.
In Britain Coelioxys quadridentata is restricted to England and south Wales. There are no records for Scotland or Ireland. The greatest density of records is from Dorset and Surrey with more scattered records from the south-east up towards Yorkshire. The bee is also recorded from Jersey in the Channel Islands.
On the near continent, the bee is found in many western European countries (including Scandinavia) from Finland to Spain and across to Slovenia in the east. Worldwide it is found in Asia from Turkey to Siberia.
