Copiula is a genus of microhylid frogs endemic to New Guinea. The common name Mehely frogs has been coined for them.[1] They are leaf-litter inhabitants.[2]
Copiula is probably not monophyletic. Some former Austrochaperina species have already been transferred to this genus, and further ones might follow when more data became available.[1][3]
The AmphibiaWeb[4] reports fewer species, with species that Peloso and colleagues moved in 2016 from Austrochaperina and Oxydactyla missing.[3]
