A new species of Bachia (Squamata: Gymnophthalmidae) with pleisomorphic limb morphology

We describe a new species of Bachia from the upper Rio Negro drainage of southeastern Colombia and southern Venezuela. The new taxon is diagnosed by a complement of phalanges that is unique among gymnophthalmid lizards and intermediate relative to other Bachia and closely related genera. Variation in limb osteology among the species of Bachia and close relatives is reported. We discuss the distribution of B. panoplia and the taxonomic status of B. flavescens.
