There really isn't a way to tell them apart as they are physically similar. Since aeneus is the much more common of the two, I'd assume you have aeneus.
I should add, you may be able to tell them apart when they reach full size (2.5"-3")...the paleatus will have a longer slimmer body and the aeneus will be broader and thick-bodied in comparison.
