Have been trying to identify it, im pretty sure its from the affinis subgroup of the obscura group. Because of the coloration, size and the fact that it has 10 row-or so of teeth in the sex combs, it should be D. algonquin or D. tolteca. Im deciding for D. tolteca since the culture trademark is mexican, still, im not completely sure if the very origin of the culture is from Mexico, or if the original culture was made with specimens from USA or another country. Still, any contribution or correction is appreciated!! I will add some more photos. Also found some white-colored flies, not sure if its because a mutation or if they were just recently hatched or something like that
