This species is known only from a non-specific type locality, in northern Halmahera Island, in the Maluku Islands, Indonesia, perhaps up to 670m asl.
Habitat and Ecology
It presumably lives in rainforest and breeds by direct development.
It has not been recorded since it was first described, and its population status is not known.
There are no data available on specific threats to this species, although there is some circumstantial evidence of extensive forest loss on Halmahera.
Its distribution, habitat requirements and abundance need to be properly documented. It is not known from any protected areas.
Red List Status
Data Deficient (DD)
Listed as Data Deficient in view of the absence of recent information on its extent of occurrence, status and ecological requirements.
