Scientific Name: Pteralopex pulchra Flannery, 1991
Common Name(s):
English Montane Monkey-faced Bat

Assessment Information [top]

Red List Category & Criteria: Critically Endangered (Possibly Extinct) D ver 3.1
Year Published: 2017

The Montane Monkey-faced Bat is listed as Critically Endangered because its population size is estimated to number fewer than 50 mature individuals, with all individuals in a single subpopulation, and if it still exists it is likely experiencing a continuing decline. This species has not been recorded since it was first discovered and surveys are needed to confirm its continued existence. Other members of the genus are susceptible to deforestation and hunting, and either of these threats could also be operating on this species.
Date last seen: 1991

Geographic Range [top]

Range Description:This bat is known from a single specimen collected on the southern slopes of Mount Makarakomburu, Guadacanal in the Solomon Islands. It was recorded at 1,230 m asl (elevational range of 1,200-2,448 m comes from Helgen 2005).

Population [top]

Population:This species is known only from the holotype. Extensive surveys at 1,000 m and 1,300-1,500 m asl on the northern side of Mt Popomanasaeu in 2015 failed to record the species. The habitat present at the 1,300-1,500 m survey site resembled the description given by Flannery (1991); however, the species was not detected. It is possible the lower altitudinal limit of this species is greater that 1,500 m on northern Guadalcanal. The rain shadow may restrict montane vegetation that is suitable for P. pulchra to higher altitudes on the northern side of the island.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:0-50
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Flannery (1995, p. 242) recorded the habitat at the collection site as being "primary mossy montane forest with emergent Metrosideros and palms, and an abundant understorey of ferns and climbing bamboo". The species is likely restricted to upland areas.

Threats [top]

Major Threat(s): The threats to this species are not known. It has a restricted range that could be susceptible to a single threat event. The species likely has specific habitat requirements, given the dependence of its congeners on large hollow trees as roosts. It might also share traits that make Pteralopex species easily hunted; however, hunting pressure at high elevation on Guadalcanal appears extremely low (T. Lavery pers. comm).

Conservation Actions [top]

Conservation Actions: This species is not found in any protected areas. Survey work on the species is urgently needed to confirm its presence. Studies of the natural history of the species and threats faced by it are also needed.
