The finger and toe tips are rounded or slightly swollen but without discs; webbing is also absent. The dorsum is brown and tan with yellow outlining. The hands and feet have orange highlights. The iris is bronze. Males have a single vocal sac.[3]

Habitat and conservation

Physalaemus maculiventris occurs in primary and secondary forest at elevations of about 800 m (2,600 ft) above sea level; it can occur on the forest edge but not in more open areas. It is terrestrial frog usually found near temporary ponds or in the water. Breeding takes place in temporary ponds where a foam nest is built.[1]

Physalaemus maculiventris is a common species, but it can be threatened by habitat loss caused by agriculture, livestock grazing, clear-cutting, tourism, and human settlement. It is found in several protected areas.[1]
