Western Highland Treefrog

Litoria iris


Smallish tree frog with males at 36mm and females 43mm. Head as broad as it is long with slightly pointed snout. Dorsal surface can be variable but in this case a bright green covered in black vermiculated lines. Orange patterning on concealed surfaces of thighs and under forelegs. Purple to pale blue patches present the groin area and below abdomen.


Found on foliage beside mountian pool on Rondon Ridge near Mount Hagen in the Western Highland Province of PNG. Eggs layed on foliage above water.


Litoria iris was first described in 1962 (Tyler). There are several similar species and given the number of new species still to be described, there could well be a number of species presently within the 'iris-group'.
