Copiula  Copiula is a genus of microhylid frogs endemic to New Guinea. The common name Mehely frogs has been coined for them. They are leaf-litter inhabitants. "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. There are at present 14 species in this genus: The AmphibiaWeb reports fewer species, with species that Peloso and colleagues moved in 2016 from "Austrochaperina" and "Oxydactyla" missing.
