Description
editMales 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.[4]
Habitat and conservation
editIts natural habitats are stream margins in premontane and lower montane rainforests.[1] It was formerly abundant but has seen a drastic population decline. Last seen in 1986, it might already be extinct.[1][3] Its decline is likely to have been caused by chytridiomycosis, although climate change, pet trade, and pollution are also possible threats.[1]
