Departamento de Ica
This species is endemic from the Ica Region in southern Peru, and its known geographical distribution is restricted to the Paracas National Reservation, including two islands (La Vieja in the Bahia Independencia and Sangayan west of the Paracas Peninsula). This gecko most closely resembles "Phyllodactylus gerrhopygus" (a species that also occurs in southern Peru), from which it can be distinguished by smaller and more numerous terminal lamellae on the fourth toe.
