Thank you! This one didn’t have a white stripe - you’re right it’s just the light reflection.

Initially I too thought that this specimen was Caenoplana coerulea. However, the typical mid dorsal white stripe of this species appears on this specimen to be a reflection of the light, as in one small portion of the body where there is no reflection (near a twig), there is no white stripe. In this case, the species would be Caenoplana spenceri that also occurs in this region. Do you recollect whether or not it had a white stripe?

A freshwater triclad. Working on the ID.
