Range & Status
Southern coasts, but with very few modern records.
Known from just five localities in Cornwall and mostly old records: singly on the beach, Portscatho (Champion, 1897); Rame Head in 1902 by J.H. Keys; Mousehole in 1923 and Pentire Point in 1968, both by R.T. Bannister; and Boconnoc Park in 1972 by K.C. Side. Rediscovered at Mousehole by John Walters in 2003.
Habitat & Ecology
Under stones on rocky or sandy sea shores, near high-water marks.
The main threat would appear to be from coastal protection works.
Natural beach transitions should be protected wherever they still survive.
