Identify this Lizard? (pic)

I got a couple of pictures of this lizard while in Azacualpa, Chalatenango, El Salvador last week.

The closest I've found is Ameiva Festiva, but it really doesn't seem like an exact match, though it is obviously some sort of Ameiva lizard.

Anyone know what it is?

Ameiva Festiva looks as though it has lines/stripes down the length of its back, whereas the lizard pictured does not.
