Population [top]

Population:The species is considered to be rare, but it may be more abundant than is currently known (Bonaccorso 1998). The occurrence of this species across several biogeographic regions (mainland New Guinea, the Bismarck Archipelago, and Solomon Islands) may indicate that there is little genetic connectivity between some populations (S. Hamilton pers. comm.).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is a cave-dwelling, insectivorous species that has been recorded from mossy tropical forest (Bonaccorso 1998). Females are believed to give birth to two young per year (Bonaccorso 1998).

Threats [top]

Major Threat(s): It is threatened by deforestation and may be locally impacted by collection for food.

Conservation Actions [top]

Conservation Actions: Suitable conservation actions for this species are the protection of known roosting caves, and identification of additional important roosting sites. There are no known records of this species from protected areas, but it may occur in some within its range in Papua New Guinea.
