Abstract

We describe a new species of Microtegu lizard (Selvasaura) from the Amazonian slopes of the Andes in Ecuador. Among other characters, the new species differs from the only other known species of Selvasaura, S. brava from Peru, in having more femoral pores in males and an unilobed hemipenis. We present the first description of the skull of Selvasaura, along with a molecular phylogeny of Cercosaurinae and genetic distances as additional evidence supporting delimitation of the new species.
