Physalaemus marmoratus can be found in the states of Bahia, Espírito Santo, Rio de Janeiro, São Paulo, Minas Gerais, Goiás, Mato Grosso, and Mato Grosso do Sul (Brazil), and also in Paraguay (Nascimento et al., 2006).
Habitat and Ecology
Physalaemus marmoratus breeds in temporary shallow ponds of open habitats. Males call floating on the water with the large vocal sac inflated. During the axillary amplexus a foam nest is constructed on the water surface where the unpigmented eggs are deposited (Nascimento et al., 2006).
It does not adapt well to anthropogenic disturbance.
This is an uncommon species.
There are no major threats, although agricultural activities could be a threat in eastern Paraguay, and probably also in parts of Brazil.
It occurs in several protected areas.
Nascimento et al. (2006) associate Gomphobates marmoratus to the genus Physalaemus, and indicate that this name refers to specimens previously identified as Physalaemus fuscomaculatus.
