Cheesman's big-eyed tree frog

Cheesman's big-eyed tree frog ("Nyctimystes cheesmani") is a tree frog from southeastern Papua New Guinea.
The adult male frog is 47.6 to 56.5 mm long from nose to rear end, and the adult female frog is 54.7 to 65.0 mm long. It can be light brown to dark brown or green-brown in color. It has very dark eyes. It has purple color on some parts of its body. It has vomerine teeth in its upper jaw.
Scientists found this frog in streams in forests that were open enough for the sunlight to come through.
In 2020, the International Commission of Zoological Nomenclature considered calling the frog "cheesmanae" but decided not to.
