Papua New Guinea hosts an abundance of frog species, and there are huge areas of the country yet to be systematically studied. The chances of finding new species, especially in the rugged highland regions, is extremely high, and many species remain undescribed. Many of the smaller species, however, are hard to locate in the tangle of tree roots, ferns, mosses, leaf litter and other debris which makes up the forest floor in many hilly or mountainous areas. The species shown here are largely from lower montane forests, between 800 and 1750 metres elevation.
