Cophixalus petrophilus, the blotched boulder-frog, is a species of frogs from the Cape York Peninsula (Queensland, Australia) that was described in 2013.

[2][1] It is one of three newly described vertebrate species from Cape Melville, Australia, the other two being skink Saproscincus saltus and gecko Saltuarius eximius.

[1][3][4] The specific name petrophilus means "rock-loving" and refers to restriction of this species to boulder field habitats.

[1] The male advertisement call is a fairly short, medium-paced, low-pitched rattle (dominant frequency about 1300 Hz).

[1][4] Cophixalus petrophilus is restricted to granite boulder fields that are largely devoid of vegetation and is known from two sites a few kilometers apart on the Melville Range at elevations of 120 and 470 m (390 and 1,540 ft) above sea level.
