Marionfyfea adventor, a recently described terrestrial flatworm

First found in Britain in Cambridgeshire in 2012 (a specimen had been found in the Netherlands 3 months earlier), this was described new to science by Hugh Jones in 2016. It is assumed to originate in New Zealand or Australia; the only other member of the genus is known from Campbell Island, off New Zealand.  It has so far been found in half a dozen locations in Britain, ranging from Cornwall to Sunderland.
