A new Phymaturus species is described as a new member of the ?patagonicus? group of the genus. The Patagonian lizard genus Phymaturus is regarded as a candidate for non-adaptive radiation given the tendency toward non-overlapping distributions among its phenotypically and ecologically similar species (i.e., niche conservatism). In this paper, we provide the description of a sexually monomorphic species new to this clade. It is distinguished from other members of the patagonicus group by having metric and meristic differences, as well as by a peculiar, almost homogeneous, black colour pattern over the whole body. It lives at about 1000 m of altitude in very dark basalt rocky outcrops, in northwesternChubut Province, Argentina. The new species is morphologically compared with the closely related species of the patagonicus group, and its distribution and natural history are highlighted.
