This species is known from 1,480m asl on Mount Ngoc Linh, in Tra My District, Tra Don Commune, Quang Nam Province, Viet Nam. The limits of its distribution remain unknown.
Habitat and Ecology
This species was found in montane broad-leaved evergreen forest with small mixed coniferous areas. Streams in the area had beds comprising rock, gravel, sand and mud. Breeding in this species is presumably by larval development.
It is known from only a single specimen.
Up to approximately 900m asl on this mountain the potential habitat of this species is heavily disturbed due to clearance of forest for agriculture and timber extraction, with forests persisting only in ravines and steeper slopes. Disturbance is likely to increase if plans go ahead for building a road to Muong Hoong and Ngoc Linh communes (Tordoff 2002). At the higher altitudes where this species was actually found, disturbance levels are lower.
Ngoc Linh Nature Reserve was decreed on the Kon Tum side of the mountain by the government in 1986, but there is a need to decree a nature reserve on the Quang Nam side and to put in place a management board (Tordoff 2002).
