Abstract

A new species of diurnal gecko of the genus Gonatodes is described from Inselbergs (granite outcrops) on the western peripheral lowlands of the Guiana Shield, Venezuela. The new species can be distinguished from all congeners by the following characters: large size (the new species is the largest known sphaerodactyl gecko), supraciliary spine absent, females with immaculate brown dorsal coloration, and a subcaudal scale pattern found in only one other species in the genus. The new species is also unique in the genus in being restricted to rock outcrops and shows potential adaptations to this type of habitat.
