Oligocladus sanguinolentus

Lang, 1884


David Fenwick Snr Can someone identify this one please, it was found under a rock on the lowershore at Penzance, Cornwall, UK. Quite striking for a UK flatworm so I'm hoping someone can do it so I can record it.

Erling Svensen Anybody that knows this flatworm? 2 cm long. I do not feel it is the Oligocladus sanguinolentus, or?

Erling Svensen After some reading, could this be Leptoplana tremellaris?

David Fenwick Snr Here's a better image of the flatworm from Penzance. Is it Eurylepta cornuta?

David Fenwick Snr Done some more work on this and it looks to be Oligocladus sanguinolentus, pretty sure of this now and it checks out using Hayward and Ryland.

David Fenwick Snr A friend and I have looked into this in more detail now and we are both in agreement on looking at Lang that my first opinion Eurylepta cornuta is possibly the most likely species here.
