A new species of Riama (Squamata : Gymnophthalmidae), endemic to the Peninsula de Paria, Venezuela

摘要

A new species of gymnophthalmid lizard is describes from the montane forests of the peninsula de Paria in northeastern Venezuela. The new species is one of the three gymnophtalmid species known to be endemic to the region, and the fourth species of Riama from Venezuela. It is likely the sister species to R. shrevei of Trinidad, but can be distinguished from the latter species by having a nosoloreal suture, fewer scale rows encircling the midbody, and by having a higher number of transverse dorsal scale rows.
