This species is known from the vicinity of one small pond in the Reserva Nacional Lago Jeinimeni, southern Chile.
Habitat and Ecology
The small pond which forms the only area where this species is known from measures 68.8m by 80m, and around 50cm deep at the deepest point. Most other ponds in the area dry out in summer. In the vicinity are pine plantations and degraded Nothofagus pumilio forest. This species presumably breeds by larval development.
It appears to be fairly common within its extremely limited range.
A major threat to this species is a plan to construct a paved road crossing the reserve to improve an existing road that is currently impassable in winter. Unfortunately, the planned route passes close to the only known breeding pond, which will probably cause direct mortality and pollution, and would also isolate it from the Jeinimeni River and lake.
The known range of this species is encompassed by the Reserva Nacional Lago Jeinimeni. Studies are urgently needed prior to the approval of the planned road to assess further the ecology and, in particular, the dispersal patterns of this species. At this time, unsupervised public access to the breeding pond should be restricted, in order to remove any potential disturbance.
