This species is known only from the type locality, Merauke, in southern Papua, Indonesia, and there have been very few records since it was first discovered in the late 1960s. It occurs close to sea level.
Habitat and Ecology
It has only been found in a grassy, swampy area in the town of Merauke, where it breeds. It presumably occurs elsewhere, but its broader habitat requirements are not yet known, and surveys have not been successful in locating it.
There is no information on the population status of this species.
There is no information on major threats, but given that it occurs close to sea level it might be susceptible to habitat loss due to development in coastal areas. It has been found once in the pet trade in Jakarta.
It is not known from any protected areas. This species requires close population monitoring, given that it currently is known only from a single locality; further survey work is needed to determine whether or not it might occur more widely.
Red List Status
Listed as Vulnerable because it is known from fewer than five locations.
