Abstract: We describe a new species of riparian Litoria from the Cloudy Mountains of southeastern Papua New Guinea. The new species is a member of the Litoria nigropunctata species group and differs from other members of that group in its combination of small size, blunt snout, head wider than long, no vomerine teeth, fingers one-third webbed, red iris, and several aspects of color pattern. The new species is among the smallest members of its genus in New Guinea and apparently can be distinguished readily from all other Papuan (New Guinea and surrounding islands) Litoria by its iris color alone. The sole female has many small, white ova, but exact reproductive mode for the species remains uncertain.
