From the IUCN Red List Species Account:

Range Description

This species is known from the mountains of central Viet Nam (Orlov and Cuc, 2005). There are records from: Ba Na National Park, in Danang Province, at 1,400m asl; Bach Ma National Park (Hai Van Mountain Range), in Thua Thien-Hue Province, 1,300m asl; Huong Hoa district, in Quang Tri Province, at 400m asl; and Phong Nha – Ke Bang National Park, in Quang Binh province, at 300m asl (Orlov and Cuc, 2005). It presumably occurs more widely, especially in areas between known sites, and it can be expected from neighbouring Laos.

Habitat and Ecology

This species lives in valleys near mountain streams in evergreen forest (Orlov and Cuc, 2005). It is arboreal, but prefers the lower strata of the forest (usually 30-100cm above ground), and can be found on leaves of ferns and Gingeraceae and Araceae plants at night (Orlov and Cuc, 2005). Clutches of 5-12 eggs are found on the back surface of the leaves, sometimes with 2-3 clutches lie on the same leaf (Orlov and Cuc, 2005). The males appear to guard the egg clutches (Orlov and Cuc, 2005). It presumably breeds by direct development.

Population

It is probably common in suitable habitats.

Population Trend

unknown

Major Threats

There is no direct information on threats, but the habitat of this species is presumably being impacted by expanding agriculture and human settlements, and by logging.

Conservation Actions

It occurs in the Ba Na, Bach Ma, and Phong Nha-Ke Bang National Parks. Surveys are needed to determine its geographic distribution, abundance, ecological requirements, threats and conservations needs.

Red List Status

Data Deficient (DD)

Rationale

Listed as Data Deficient since it has only recently been described, and there is still very little known about its extent of occurrence, area of occupancy, status and ecological requirements.
