Nyctimene albiventer occurs in the Halmahera Islands, Banda and Aru Islands, Bismarck Archipelago, Moluccas, New Guinea, Admiralty and Solomon Islands and the Cape York peninsula of Australia (Nowak, 1999; Boitani, 1982).
Biogeographic Regions: oriental (Native ); australian (Native )
Other Geographic Terms: island endemic
These bats are not known to have a negative impact on human economies.
These bats have no special conservation status. However, several members of the genus are near threatened, vulnerable, or critically endangered according to the IUCN. Habitat destruction seems to be the principle threat to the genus, and it is likely that deforestation could eventually affect N. albiventer as well as its close relatives.
CITES: no special status
IUCN Red List of Threatened Species: least concern
Although not much is know about how N. albiventer communicates, it is known to emmit high whistling calls in mid flight. Their peculiar nostrils may be an adaptation to their feeding habits or may function in sound production. The nasal tubes stretch and vibrate when the bat utters its high whistling call in flight (Boitani, 1982).
Communication Channels: visual ; acoustic
Perception Channels: tactile ; chemical
There appears to be considerable active debate regarding the taxonomy of this genus of bats. Authorities sometimes split populations on different islands into different species or subspecies. Other authorities lump various island populations together as a single species. It is likely that these problems of taxonomy affect whether species are viewed as threatened or endangered (Nowak, 1999).
There are no known positive interactions between these bats and humans.
Since N. albiventer is a frugivore, it may play an essential role in seed dispersal for many of the local plant species.
Ecosystem Impact: disperses seeds
N. albiventer is known to mainly be a frugivore. However, Vestjens and Hall (1977) reported that the stomachs of three N. albiventer individuals contained insects. Most other stomachs contained fruit or vegetable matter. Earlier observations indicated that captive individuals prefer soft, juicy fruits and would not take insects that were offered.
In order to eat, the animal hangs horizontally or obliquely in a fruit bush with its thumbs inserted into the fruit. It turns its lips up on the fruit and bites off pieces with its lower jaw. The upper teeth aid the lips in supporting the lower jaw. The bat shoves the bitten pieces toward its breast and the belly with its muzzle, then vhews them up to extract the juice. A fringe of fleshy lobes on the inner edge of the lips seems to assist the bat in this processing. Captives that fed on guavas were not observed to bite into the inside of the fruit, and the nostrils did not come in contact with the fruit at any time. The pulp of young coconuts is also eaten (Nowak, 1999).
Foods eaten include: soft fruit, nectar and some insects.
Animal Foods: insects
Plant Foods: fruit; nectar
Primary Diet: herbivore (Frugivore )
Known to inhabit primary and secondary rainforest, primary montane forest, sago swamp, and areas surrounding native gardens (Nowak, 1999).
Habitat Regions: tropical
Terrestrial Biomes: forest ; rainforest
Wetlands: swamp
Other Habitat Features: agricultural
The lifespan of these bats has not been documented.
N. albiventer is a medium-sized, yet robust fruit bat with a large, rounded head. These bats have large eyes, long, tubular nostrils that extend sideways from the face, and a short tail. The fur is soft and long, grayish brown above, but darker along mid-back and on the spinal stripe. The underparts are usually yellowish-white. The neck and sides are tinged with yellow-orange. The ears and wings are splattered with irregular yellow spots. This mottled fur may help them to remain concealed while hanging in their resting position (Nowak, 1999). The length of head and body about 8-9 cm. The forearm is 5.5-6 cm (2.2-2.4 in) long. These bats weigh up to 45 g (1.6 oz). (Boitani, 1982)
Range mass: 45 (high) g.
Range length: 8 to 9 cm.
Other Physical Features: endothermic ; bilateral symmetry
Predation upon these bats has not been reported. However, it is thought that the mottled pattern on the fur may help them to remain concealed while they are in their resting position (Nowak, 1999).
The mating system of these bats is unknown.
Reproductive behavior is not well documented for this species. N. albiventer may have two annual breeding seasons, in early winter and in late summer, or they breed year-round. Pregnant females with one embryo each have been taken in January, July, and August. Lactating females have been taken in February, May and August (Nowak, 1999). All records on reproduction emminate from Papua New Guinea, so breeding season may vary in ther locations.
Records for congeneric N. rabori indicate that preganancy lasts 4.5 to 5 months, and lactation continues for 3 or 4 months. Females can first become pregnant at 7 to 8 months of age (Nowak, 1999).
Breeding season: Breeding may occur year round, and pregnant females have been taken in January, July, and August.
Average number of offspring: 1.
Key Reproductive Features: iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (Internal ); viviparous
Females nurse the young. Male parental care has not been reported, but little is known about reproduction in these animals.
Parental Investment: female parental care

The common tube-nosed fruit bat (Nyctimene albiventer) is a species of megabat in the family Pteropodidae. It is found at islands north of Australia, and in Indonesia, Papua New Guinea, the Philippines and the Solomon Islands.
The first description of Nyctimene albiventer was provided by John Edward Gray in 1863, and allied the species by the combination Cynopterus albiventer.[2] The type, representing subspecies Nyctimene albiventer albiventer, was obtained at the Moluccas island group.[3] A part of the population which occurs on mainland Australia was recognised by this name, but specimens described by Oldfield Thomas were assigned to the species Nyctimene robinsoni in 1904.[3] The name also encompasses populations at locations which are morphologically distinct, in two separate species complexes distributed across the region, with probable and unnamed taxa sometimes occurring in sympatry; up to three sympatric species may be discerned on the main island of New Guinea.[1]
An available name, recognised as a synonym of the species, is Nyctimene papuanus K. Andersen, 1910.[1]
The species-group is generally solitary and adopts a daytime roost in dry foliage of the lower to mid storey of the forest. The reproduction is typical of megabats, with a single birth once a year. The offspring is carried by the mother until it advances to an age where it can be left behind while feeding.[1]
Common tube-nosed fruit bats are primarily frugivores, thriving on raw fruits. To eat, the bat will bite off small chunks of fruit while hanging horizontally. However, occasionally they are also known to eat nectar and the remains of insects.[4]
The species occurs at the islands north of Cape York peninsula in Australia, but has not been recorded on the mainland. The distribution range of Nyctimene albiventer, so named, extends from the main island of Papua New Guinea to the Indonesian territories and on the region's smaller island groups. The various forms and populations are found at all altitudes below 1,900.[1]
The IUCN classifies the species by the conservation status least concern, but recognises the likelihood of separation of the species and the need for individual revision of these. Some island populations, such as those at the Kei and Moluccan Islands or the Admiralty and Bismarck groups, may be in decline due to acknowledged threats in the region, although the extent of the impact on any putative species has not been evaluated.[1]

Nyctimene albiventer o murciélago de nariz tubular es una especie de murciélago de la familia Pteropodidae. Fue descubierta en 2009 en Papúa Nueva Guinea.
Este mamífero volador pesa menos de ¼ de onza y mide aproximadamente una pulgada de longitud.[2] A diferencia de la mayoría de especies de murciélagos, este utiliza sus grandes ojos (con visión estereoscópica ) para moverse y conseguir su alimento.[3] Su pelo es claro, usualmente gris amarronado,con la cabeza más pálida y las alas con manchas amarillentas.[4] La mayoría de las características morfológicas que separan a este murciélago de otras especies están asociadas con una mandíbula más ancha y redonda que da la apariencia de una sonrisa constante.[5]
El murciélago de nariz tubular es frugivoro, por lo que su dieta está compuesta por frutas y gracias a su alimentación, se ha convertido en un excelente ayudante para su ecosistema, ya que al llevar consigo las frutas caen algunas semillas y estas permiten que surjan nuevos árboles o plantas a varios kilómetros de distancia.[6]
Se encuentra en Australia, Indonesia, Papúa Nueva Guinea, y las Islas Salomón.

Il pipistrello della frutta dalle narici a tubo comune (Nyctimene albiventer Gray, 1863) è un pipistrello appartenente alla famiglia degli Pteropodidi, diffuso in Nuova Guinea e Isole Molucche settentrionali.[1][2]
Pipistrello di medie dimensioni, con la lunghezza della testa e del corpo tra 65,5 e 98 mm, la lunghezza dell'avambraccio tra 51 e 61 mm, la lunghezza della coda tra 17,9 e 30,1 mm, la lunghezza del piede tra 11,3 e 18,4 mm, la lunghezza delle orecchie tra 8,5 e 18,6 mm, un'apertura alare fino a 43,6 cm e un peso fino a 38 g e un'apertura alare fino a 43,6 cm.[3]
Le parti dorsali sono marroni, mentre le parti ventrali sono bruno-giallastre lungo i fianchi e il basso ventre, color crema sull'addome. Lungo la spina dorsale è presente una sottile banda bruno-nerastra, larga appena 2 cm, indistinta nel primo terzo della schiena nella sottospecie N.a.albiventer, mentre è ben più visibile in N.a.papuanus. Il muso è corto, tozzo e largo, gli occhi sono grandi, con l'iride color ambra. Le narici hanno la forma di due piccoli cilindri che si estendono ben oltre l'estremità del naso e sono spesso ricoperte di macchie gialle. Le orecchie sono ben separate tra loro, ovali e ricoperte esternamente di macchie giallognole. Le ali sono nero-verdastre, ricoperte di macchie chiare e scure e sono attaccate posteriormente alla base del secondo dito dei piedi. La coda è corta e si estende completamente fuori dall'uropatagio, il quale è ridotto ad una sottile membrana lungo la parte interna degli arti inferiori. La sottospecie N.a.albiventer è la più piccola.
Si rifugia singolarmente nella densa vegetazione. Entra in uno stato di torpore durante il giorno.
Specie principalmente frugivora, sebbene siano stati rinvenuti resti di coleotteri, formiche e falene nei residui digestivi di alcuni individui catturati.[3]
Le femmine danno alla luce un piccolo alla volta all'anno. Femmine gravide sono state catturate in Nuova Guinea nei mesi di gennaio, febbraio, luglio, agosto e settembre.
Questa specie è diffusa in Nuova Guinea e Isole Molucche settentrionali.
Vive nelle foreste pluviali primarie fino a 1900 metri di altitudine, mentre è meno frequente nelle foreste secondarie, nelle foreste di palme da sago, nei giardini, nelle piantagioni, nelle savane di Melaleuca e nelle foreste monsoniche.
Sono state riconosciute due sottospecie:
N. minutus (Andersen, 1910), dell'isola di Sulawesi, è considerato un individuo di N. albiventer con l'indicazione geografica d'origine errata.[1]
Altre specie simpatriche dello stesso genere: N. aello, N. cyclotis, N. certans, N. cephalotes, N. keasti e N. major
La IUCN Red List, considerato il vasto areale e la popolazione numerosa, classifica N. albiventer come specie a rischio minimo (LC).[1]

Nyctimene albiventer is een vleermuis uit het geslacht Nyctimene die voorkomt op Nieuw-Guinea en in de Molukken. Deze soort behoort tot de N. albiventer-groep. Veel van de andere soorten uit die groep, zoals Nyctimene draconilla, worden vaak ook tot N. albiventer gerekend. Nyctimene keasti (een soort uit de N. cephalotes-groep) werd oorspronkelijk ook beschreven als een ondersoort van N. albiventer. De Nieuw-Guinese populatie wordt als een aparte ondersoort gezien, N. a. papuanus Andersen, 1910. De populatie op de Aru-eilanden is niet in een ondersoort geplaatst. Het is mogelijk dat de soort ook op Nieuw-Brittannië voorkomt; de taxonomie van de oostelijke leden van de albiventer-groep is zeer verward.
N. albiventer is een middelgrote soort met een smalle rugstreep. De kop-romplengte bedraagt 68,0 tot 82,9 mm, de staartlengte 17,3 tot 24,9 mm, de voorarmlengte 49,4 tot 57,4 mm, de tibialengte 18,1 tot 24,9 mm, de oorlengte 11,5 tot 13,9 mm en het gewicht 22 tot 33 g.

Nyctimene albiventer[2][3] är en däggdjursart som först beskrevs av Gray 1863. Nyctimene albiventer ingår i släktet Nyctimene och familjen flyghundar.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1]
Inga underarter finns listade i Catalogue of Life.[4] Wilson & Reeder (2005) skiljer mellan två underarter.[6]
Denna flyghund förekommer på Nya Guinea och på Moluckerna. Arten vistas i låglandet och i bergstrakter upp till 1900 meter över havet. Habitatet utgörs av regnskogar, andra skogar, savanner med trädgrupper och trädgårdar. Individerna vilar gömd i den täta växtligheten. Honor kan para sig under olika årstider och per kull föds allmänt ett ungdjur.[1]
Arten når en kroppslängd (huvud och bål) av 8 till 9 cm, en underarmlängd av 5,5 till 6 cm och en vikt av cirka 45 g. Svansen är bara en liten stubbe. På ovansidan har den långa mjuka pälsen en gråbrun färg som är mörkare på ryggens mitt. Undersidan är däremot gulvit och vissa ställen kan ha en orange skugga. Det stora runda huvudet kännetecknas av stora ögon och rörformiga näsborrar. På öronen och på flygmembranen förekommer gulaktiga punkter.[7]
Nyctimene albiventer letar på natten efter mjuka frukter och den äter även blommornas nektar. I magsäcken av några individer hittades dessutom rester av insekter. Hos andra arter av samma släkte är honan 4,5 till 5 månader dräktig och ungen diar sin mor 3 till 4 månader. Antagligen har Nyctimene albiventer ett liknande fortplantningssätt. Punkterna på vingarna tolkas som kamouflage.[7]
