The Guadarrama Wall Lizard is specialized on the granite rock substrates of western-central Iberia. No granite rocks - no Podarcis guadarramae! It mainly occurs in the mountain ranges of the Sistema Central - from Sierra del Alto Rey (Guadalajara) in the east to Sierra de Guadarrama, Sierra de Gredos and Peña de Francia. For distribution range see map at Podarcis hispanicus.
Podarcis guadarramae differs from the neighbouring Iberian Podarcis species by its flattened head and elongated snout. It has contact zones or overlapping ranges with the following species:
Podarcis guadarramae may also co-occur with Podarcis muralis (e.g. Sierra de Guadarrama / Madrid). The latter one is much bigger than Podarcis guadarramae and frequently shows prominent blue outer ventral scales and orange throats.
