[Herpetology • 2004] Petracola labioocularis (originally Proctoporus) • new Proctoporus (Squamata: Gymnophthalmidae) from Peru, with a Key to the species of Euspondylus and Proctoporus from Peru

Petracola labioocularis (Köhler & Lehr, 2004)

Type locality: Peru, Departamento de Huánuco, Chaglla, 2980 m elevation
Holotype: MHNSM 20092
Basonym: Proctoporus labioocularis Köhler & Lehr, 2004

Etymology.- The  name labioocularis is  an  adjective and is formed from the Latin words labium  (lip)  and oculus (eye). The name is used in reference to the distinctive supralabial-subocular fusion found in all specimens of this species.

We describe two new species of Proctoporus and a new species of Euspondylus (all from central Peru, Departamento de Huanuco, 2545 to 3010 m elevation). The new species are distinguished from all species presently assigned to Proctoporus and Euspondylus by unique characteristics of pholidosis, morphometrics, and color pattern. A key to the Peruvian species of Proctoporus and Euspondylus is provided. The current allocation of species to Proctoporus and Euspondylus may not reflect the phylogenetic relationships of the species  under consideration. Based on the  available data there  appears to  be  no  evidence to justify the separation of these genera. However, because of nomenclatural problems that would arise from synonymizing the two genera (e.g., producing a secondary homonymy in the case of Proctoporus guentheri Boettger and Ecpleopus guentheri O'Shaughnessy), we  chose to  retain the two genera until phylogenetic information is available.
