Above, a Spiny Bottom Tree Frog is a mixture of olive, chestnut and reddish-brown spots, while below it is mostly white, with tiny black spots and some larger black markings on the belly.

Whereas the skin on the underside is mostly uneven and bumpy, above it is mostly smooth, apart for some small bumps, that are brownish to coppery in colour. Those blunt spines, somewhat reminiscent of goose bumps, are scattered all over the back, yet appear in a greater concentration towards the rear. The eyes are golden brown with a little black in the irises.

In 1999, this species was recorded by scientists to dwell at a height of 900 meters above sea level, this one however was in fact spotted at a height of about 1,200 meters above sea level near the village of Xa Linh in Hoa Binh (Hòa Bình) Province.
