Scientific Name: Nyctimene albiventer (Gray, 1863)
Common Name(s):
English Common Tube-nosed Fruit Bat, Common Tube-nosed Bat
Nyctimene papuanus K. Andersen, 1910
Taxonomic Notes: Many different morphologically distinct forms of tube-nosed fruit bat have been grouped under this name, sharing in common little more than their relatively small size. In reality, the name albiventer currently subsumes members of at least two quite different species complexes that are not particularly closely related to each other. The typical form N. a. albiventer was described from the Moluccas and appears to be endemic to that region. Multiple distinct taxa are present on the main island of New Guinea, often with two or more distinct forms occurring in sympatry. Populations on surrounding island groups including the Aru, Rajah Ampat, Admiralty, St Matthias and Solomon Islands, the Kei Group, the Bismarck Archipelago, all require clarification of their taxonomic status. There are several available names including papuanus and bougainville, but some forms appear to be unnamed. Another member of this group is draconilla, which has been recognised as distinct from ‘albiventer’ on the main island of New Guinea but without any clarity about its diagnostic morphological characters or distribution. Simmons (2005) considers the Bismarck Archipelago and Solomon Islands to support populations of a separate species, N. vizcaccia, but note that an additional form of ‘albiventer’ is also present on the islands of the Bismarck Archipelago.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-03-10
Assessor(s): Aplin, K. & Armstrong, K.
Reviewer(s): Mildenstein, T.
Contributor(s): Bonaccorso, F.J. & Helgen, K.
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is not believed to be declining across many parts of its geographic range. However, because this species will be split into a number of component species and subspecies in the near future, it is likely that some populations (such as those on the Kei and Admiralty Islands) may be of conservation concern.

Geographic Range [top]

Range Description:This composite ‘species’ has been recorded from the islands of Halmahera, Obi, Batjan, Waigeo, and Salawati (all Indonesia), and eastwards to the island of New Guinea (Indonesia and Papua New Guinea) and its various satellite groups including the Aru and Kei Islands (Indonesia), the Admiralty Group and the Bismarck Archipelago (Flannery 1995a,b). The total elevational range of all members of the group is from sea level to 1,900 m a.s.l.
Countries occurrence:
Indonesia; Papua New Guinea

Population [top]

Population:Across much of the Moluccan and Melanesian regions, small tube-nosed fruit bats of the general ‘albiventer’ form appear common. Bonaccorso (1998) and Flannery (1995a) reported that it was one of the most abundant fruit bats found in the primary rainforests of Papua New Guinea but in some areas forms of ‘albiventer’ can be equally abundant in garden and secondary forest habitats. All members of the ‘albiventer’ group are much less abundant at higher elevation and peak taxonomic diversity and abundance is probably attained within the Hill Forest zone between 100 m and c. 600 m a.s.l.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Members of this group can be locally abundant in primary lowland rainforest, hill forest, Melaleuca savannah and monsoon forests, and in derived secondary forest, native gardens and sago palm and other plantations. During the day animals roost singly or in mother-infant pairs within understorey to mid-canopy vegetation, usually among dry leaves. Pregnant females have been collected on New Guinea in almost every month but there is good evidence for seasonal reproduction at some localities, albeit without island-wide synchrony. As in all other pteropodids, females carry a single embryo and the young are initially carried during foraging activities but later they are left behind at a roost site. Gestation and weaning periods are not known.

Threats [top]

Major Threat(s): Habitat clearance and conversion to monoculture plantations represent the only significant known threats to this species. These threats may be particularly pressing on the Moluccan and Kei Islands, and on the islands of the Admiralty and Bismarck groups. All members of the albiventer group are too small to be systematically hunted and their habit of roosting singly through the canopy would makes them difficult to harvest efficiently.

Conservation Actions [top]

Conservation Actions: This species is likely to be found in almost every protected area within its broader distribution. Work is needed to determine the taxonomic status of populations on the main island of New Guinea where several species of the group may be found in sympatry, and on the Kei Islands, the Bismarck, Admiralty and St Matthias groups, and in the Solomon Islands. Once the taxonomy is resolved, the status of individual species will need to be reassessed and taxon-specific conservation measures may need to be developed.
