I quote "Ligia exotica Roux, 1828 has a circum-tropical coastal distribution. There are lots of Ligia (an ancient genus) scattered around the planet, but L.oceanica is our (only) north-western European representative. Ligia italica (which looks a bit similar) occurs around the Mediterranean (but doesn't make it onto the Atlantic coast)."
