Description

Adult males measure 22–31 mm (0.87–1.22 in) and females 25–32 mm (0.98–1.26 in) in snout–vent length. The head is narrower than the plump body. The eyes are relatively small. The tympanum is barely visible. The dorsum is mottled in two shades of brown; small areas of paler ground color are occasionally showing through (coloration is highly variable between individuals and areas). Both the fingertips and toe tips are flattened but not disclike. There is no webbing between the fingers or the toes.[2]

The male advertisement call has been variously described as "woodeny croaking", "soft chirping krrr, krrr not unlike that of a cricket", and "a single short enh, rapidly repeated".[2]

Habitat and conservation

Its natural habitats are alpine grassland with tree ferns. It is very common in suitable habitat. There are no known threats to this species, although it could be impacted by fires.[1]
