Pithecopus

Pithecopus is a genus of frogs in the family Phyllomedusidae. These frogs live in tropical South America east of the Andes, from southern Venezuela to northern Argentina. 

For a while, scientists thought Pithecopus was another name for the subfamily Phyllomedusa in the family Hylidae.  However, in 2016, they changed it to Phyllomedusa hypochondrialis group. Its sister group is Callimedusa.

Name
The name of this genus comes from the Greek word pithekodes, which means "ape-like."

Description
Pithecopus frogs are medium-sized, measuring about  in snout–vent length, which means from nose to rear end. On their feet, Toe I is much longer than toe II, and is opposable to it like a thumb. 

These frogs do not have vomerine teeth. The tadpoles have a moderately small oral disc on the bottoms of their bodies, near the front.

Species
There are 12 species in this genus:

However, AmphibiaWeb lists only some of these species (Pithecopus araguaius, Pithecopus rusticus, and Pithecopus gonzagai). It puts the others in Phyllomedusa.
