The dark blotch area in the posterior, above the lateral line usually means bifasciatum to me, although most of the species in the complex are very similar in appearance. So as Buphy said, coatzacoalcos is a distinct possibility, as is hartwegi, especially it it has an overbite (one of hartwegi's distinctive traits).
And even within the bifas species, there are many location (color variants)
Below is a Rio Candeleria bifas I had to compare.
