Look like U folds. Better pictures of the jaw and sides so we can be certain.
For microlepis need a ll scale count and source of where it was imported from. Jaws will look like mala.
The folds look wide enough to call prematurely Australis. But it I would need out of tank shots and pore counts. As in tank shots can be tricky cause of fish movement. Can't see any of it completely.
