A new species of arboreal microteiid lizard of the genus Euspondylus (Gymnophtalmidae: Cercosaurinae) from the Andean slopes of central Peru with comments on Peruvian Euspondylus

Abstract

We describe a new species of arboreal gymnophtalmid lizard from the eastern Andean slopes in central Peru. Euspondylus excelsum sp. nov. is assigned tentatively to this genus for the presence of a transparent and divided lower palpebral disc, a pair of prefrontals, striated, subimbricated and homogeneous dorsal scales, lateral scales reduced in proximity to ventrals, and a discontinuous series of femoral pores in males and females. We include a revision of the type material of E. maculatus and clarify morphological differences with the new species. Finally, we discuss the taxonomic status of Peruvian species of Euspondylus.
