The peninsular rock agama or South Indian rock agama (Psammophilus dorsalis) is a common species of agama found on rocky hills in south India. An allied species, Psammophilus blanfordanus, is found in the Eastern Ghats, but north of the range of this species.
Males bask openly on exposed rocks and show head push-up displays. The larger males take up higher perch positions. They flatten their bodies when birds fly overhead. Densities of about 90 lizards per hectare have been noted.
