Description

Males measure 28–32 mm (1.1–1.3 in) and females 30–43 mm (1.2–1.7 in) in snout–vent length. Males are bluish gray, blue-green, black, or occasionally greenish, without patterning. Females may have patterning consisting of cream, lemon, or lime-coloured lighter areas.

§2

Range & habitat

Its natural habitats are stream margins in premontane and lower montane rainforests. It was formerly abundant but has seen a drastic population decline. Last seen in 1986, it might already be extinct. Its decline is likely to have been caused by chytridiomycosis, although climate change, pet trade, and pollution are also possible threats.
