Anolis laeviventris
—
White Anole

This is not one of the most distinctive Anolis species around, but fortunately there aren't too many species found in this area so process of elimination goes pretty far. They have dirty white dewlaps, but I didn't annoy this sleeping lizard by checking its dewlap.
Here is a list of all the reptiles and frogs I saw on this trip to Guatemala.

I believe that the females are the striped ones, but I haven't confirmed that.
