This frog lives in Guayas, Cotopaxi, and Los Ríos in Ecuador. It lives in dry tropical forests where the trees are 20 m or shorter with many smaller plants nearby. Within these forests, the frogs are found in places where people removed some of the vegetation. Scientists believe the frog may have evolved in open areas and then retreated to the forests because of habitat loss as humans changed Ecuador's open flooded grasslands. Scientists have seen the frog between 15 and 300 m (49 and 984 ft) above sea level.. Scientists have reported the frog in protected places: Reserva Cerro Masvale, Reserva Ecológica Andrade Jauneche, and Reserva Ecológica Manglares Churute.

Scientists named the frog for the people who live in Guayaquil in Guayas Province.
