Range & Status
Wells (1970) includes an unconfirmed record of E. gracilis from the Isles of Scilly and
another - or the same - species has been found in the Penwith Peninsula. As E. gracilis was poorly described, and all other northern hemisphere records are from the Mediterranean, it is omitted from the British fauna pending further material being examined (Huys et al ., 1996).
