[3] With an average snout-vent length of 1.5 – 2.5 cm, it is the smallest amphibian recorded in the territory.

All digits have small toe pads, which allow the frog to hang on tree branches or leaves.

The habitat of the frog is well-wooded areas near small streams or other water sources suitable for breeding.

This frog usually sits on low bushes, buries itself in fallen leaves, or rests on bare ground.

[3][4] Its tadpoles and eggs are susceptible to predation by the introduced mosquitofish, and it is only able to breed in places where the fish has yet to colonise.

[4][5] Over 200 individuals of the species were rescued from Chek Lap Kok in 1992, before the construction of the new Hong Kong International Airport.

The captives were bred successfully and the offspring were released into eight selected sites in Hong Kong Island and New Territories.
