(Barygenys exsul)
Barygenys exsul is a species of frog in the family Microhylidae. It is endemic to Papua New Guinea. It is known from Rossel (type locality) and Sudest Islands in the Louisiade Archipelago, east of New Guinea. It is uncertain whether the specimens from Sudest really are conspecific with this species. Barygenys apodasta and Barygenys resima were mixed with this species prior to their described in 2013.
