Two new species of Geckobia Mégnin, 1878, Geckobia andina n. sp. and Geckobia circumdata n. sp., ectoparasites commonly reported on geckos, are described from the host species Phyllodactylus gerrhopygus (Wiegmann). The specimens were collected in the subtropical region of the Andean Pacific of Peru. The geographic distribution of species of Geckobia in South America and the Caribbean are mapped. Furthermore, a dichotomous key for the species of New World Geckobia is provided.
