predatory terrestrial planarians

[Douglas Yanega]

Yesterday I saw one of the most amazing things ever in my life, as I
watched a black-and-yellow racing-striped planarian chase a slug up a tree,
catch it, wrap around it, and kill it. Since there isn't any "terrestrial
planarian" mailing list, I thought I'd solicit here if anyone knows of this
beastie - name, distribution, known prey habits, etc.

Thanks,
