AC Cory Club

I have 4 sterbai cories and 4 cories that were sold as pandas but really aren't. Can you let me know what they really are?
I believe they are corydorus mellini, the false bandit cory.

Mellini have a stripe from the base of the dorsal to the bottom of the caudal peduncal, kinda diagonal. Metae have a stripe from the dorsal base to the top of the caudal peduncal, not quite along the spine & from top to bottom on their caudal peduncal.
