Nomada errans var. korleviciana FRIESE 1921; Nomada errans var. sibirica FRIESE; Nomada transsylvatica ZILAHI-KISS 1927
This small Nomada was only recognised as British in 1944 (Spooner 1946) but had been found much earlier, in 1878, by C.W. Dale, although he failed to recognise the species. It is one of our most localised bee species, but has not been seen since 1982, despite several recent searches.
Restricted to a small area of coast on the Isle of Purbeck, Dorset. Widespread in southern Europe, but nowhere frequent.
