The lack of or presence of only tiny black lateral spot is basically the first thing I take note of when identifying (or at least narrowing down the identity of) suranamensoid-type earth eaters.
Literally translated, 'altifrons' = 'high forehead', referring to the prominent slope of the forehead as seen in this species' profile.
Very impressive fish you've got there. Not many folks get to see this species at such large sizes.
