Thanks to Ned Johnston for spotting this one.
Flatworm approx 10mm in damp boggy area under log. Light and dark brown-grey patches with speckling throughout. White underside. Two eyes visible with naked eye one on each side of head, at least I'm guessing they are eyes. Sorry about the photo quality. its was hard to get good detailed pics of such a small flatworm.
With paired eyes, the specimen belongs to the Rhynchodemini. The grey and white speckled dorsum, and the un-speckled ventral surface are similar to an undescribed species that I have previously found in Victoria. The other grey and white speckled species is Anisorhynchodemus simulans that is found in Victoria and Tasmania, but it has a speckled ventral surface. Thanks for closely checking the eye pattern, and especially the ventral surface.
