I have collected it there, myself.  It's often crawling around on the
sidewalks after a winter rain.  In Louisiana, locals would sometimes bring
one into the University after finding one under their dog, fearing a
parasite.  But it was usually that the animal crawled under a dog on a
concrete stab (warm canine + cool concrete = 100% humidity environment).

I read in the little black book on British Planarians* that Bipalium
kewense (which may not be the one originally asked about) is a tropic
species which is not able to sexually reproduce in temperate environments,
but it is suggested to propagate here only by asexual (fission?) means.
