Terrestrial Planarian

[GaryGaston]

I found a terrestrial planarian on the sidewalk today (in Oxford, Mississippi). I have found Bipalium before, but this one is different. It is evenly chocolate brown, and has a pointed anterior (not at all spade-like). Is there an introduced species like this known for this region? Thanks.

Added an hour later: this specimen is 10cm long, about the size of Bipalium.
