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.

Euspondylus excelsum sp. nov.

Etymology. The specific epithet “excelsum” is from Latin and means “tall”, in reference to the habitat of the new species in the canopy of the tropical rainforest.
