Hylodidae is a family of frogs.[1][2][3] Whether their sister taxon is the Dendrobatoidea or Alsodidae is still under debate. They are native to Brazil and northern Argentina.[1]

Megaelosia is one species that lost the ability to produce vocalizations which in turn are denoted as mute. Through observation of aggressive interactions, it was found that the species vocal sacs are used for one form of their visual signaling and communication. [4]

Diversity

The family contains 46 species in three genera:[1][2]

Crossodactylus Duméril and Bibron, 1841 (14 species)
Hylodes Fitzinger, 1826 (25 species)
Megaelosia Miranda-Ribeiro, 1923 (seven species)
