The genus Physalaemus is currently placed in the family Leiperidae. The most relevant literature about the family Leiuperidae. Grant and colleages removed the family from the synonym of Leptodactylidae based on molecular data.
The taxa sampled by those authors were Pseudopaludicola, Physalaemus, Pleurodema and Edalorhina. The family is the sister taxon of a clade composed by the family Bufonidae and Hylodidae, and other Dendrobatoidea. There is no morphological synapomorphy for the family.
The genus Physalaemus comprises currently 46 species, divuded into 7 species groups. The species goups within the genus Physalaemus were reviewed recently by Nascimento and colleages, who removed from the genera Engystomops and Eupemphix fom its synonym. Despite some criticism, their arrangement has been folowed by several authors. The diagnosis og the genus is fully based on adult traits
There are several ecomorphological guilds among tadpoles. They are partially represented here. Carnivores, school of suspension feeder, macrophagus, arboreal, nektonic and benthic (Bufo or Rhinella)
All tadpole of the family Leiuperide present a “pond-type” tadpoles, lentic: benthic. Not so much variation in the body shape.
