This anole suns near the lab at the Las Cruces lab most days, and I was recently able to catch and key it.  This is likely a female; she lacks a prominent dewlap.  Norops biporcatus is a large anole that is most often bright green and resembles Dactyloa spp. and Polychrus spp., because of its size.  However, presence of elongated, unkeeled lamalle on its toes, and dorsal + nuchal ridges help to place it in Norops.  I was really hoping for a Polychrus: the Neotropical chameleon… but it was still fun to catch.
