For all flatworms, especially the small very dark grey - black species, it is very helpful if the observer can check out the ventral side and include these observations in the notes. In this case, P. atrata has three dark ventral stripes, and this would help confirm the ID.
I looked at the ventral side as best I could, I did not have my hand lens, but it just seemed black all over. Hard to get detail with the naked eye from these small specimens.
