Sort of looks like a female aeneus. Hard to tell from that photo though. Lots of variation in aeneus. But the babies and juveniles are pretty specific looking. I produced lots of these in captivity over the summer. Easy species.
Adults and juveniles. Male and female.
Aeneus belongs to the roquet group so it's easy to see how they can be confused. Plus they aren't native to Guyana so that doesn't help either. It's very possible they can and do hybridize with roquet.
