Physical description
The Pearson's Tree Frog is a small tree frog growing up to 45 mm in length. Its dorsal surface can range from being completely light green, to a mixture of green and brown, or mostly brown. There are usually black dots scattered over the dorsal surface, but in some specimens these dots may not occur. The belly is white, or off white. There is a light brown/yellow stripe that starts at the tip of the snout, through the nostril and eye, through tympanum and then widens and dissipates over the shoulder. This line is underlined with a thicker dark brown line. The tympanum of this species is brown or mostly brown, not green.

Ecology and behaviour
This species inhabits flowing creeks in rainforests and wet scleophyll forest in highland and coastal areas. Males call from creek side vegetation during spring and summer. The call is an eh-eh-eh-eh-eh-eh-ehk, with the 'eh's getting faster towards the end of the call, almost forming a trill.The taxonomy of this species and the Mountain Stream Tree Frog
