Lemuroid ringtail possums may disperse the seeds of some of the fruits they eat.
Ecosystem Impact: disperses seeds
Carpet pythons (Morelia spilota) and rufous owls (Ninox rufa) are the only known predators of Hemibelideus lemuroides. Both predators hunt these possums in the forest canopy.
Lemuroid ringtail possum families band together in a tight cluster when they sense danger. This may dissuade predators from engaging due to sheer numbers. Also, this allows adults to keep their young safely in the pack's middle.
Known Predators:
Lemuroid ringtail possums are small to medium sized animals, with a body length of 30 to 38 cm and a tail length of 30 to 35 cm. Male weights range from 810 to 1060 g, females from 750 to 1140 g. Covered in long fur, the body is uniformly colored: brownish-gray on the back, head, and shoulders, with a yellowish underbelly. A rare white form of H. lemuroides has been documented and is found in unusually high proportions on Mount Carbine. The tail is covered in the same dark fur, with only the tip being bare. The bare tip acts as a friction pad to allow H. lemuroides to climb and grab objects. The highly prehensile tail also aids in steering when these possums throw themselves from tree to tree in great leaps. Each forelimb ends in 5 freestanding digits with an extended hallux to improve grip. Sharp nails on the end of each digit are long and curved, acting like a grappling hook. On the hindlimbs, the second and third toes are fused, making H. lemuroides syndactylous. The most distinctive feature of lemuroid ringtail possums, and the feature most often used by field researchers to identify them, is the color of their eyeshine. The eyeshine, or the color the tapetum lucidum appears to reflect, is bright yellow. Lemuroid ringtail possums are the only animals in the area to have yellow eyeshine.
Adults and young can only be distinguished by comparing body size and eye markings. Young are slightly smaller, have silvery eyeshine, and their eyes are closer together. However, these features are not easy to distinguish when the animals are high up in the canopy.
Lemuroid ringtail possums are very distinctive because of their odd assortment of possum, lemur, and glider-like features. The similarities between these possums and lemurs are in facial characteristics, including short snouts, large, forward-facing eyes, and small ears. Furthermore, similar to gliders, H. lemuroides have skeletal and musculature adaptations to accommodate a leaping lifestyle. Sometimes said to represent an early morphological stage of gliding, H. lemuroides have a flap of skin along their sides that is about 25 mm wide.
Range mass: 750 to 1140 g.
Range length: 30.5 to 38 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: female larger
Lemuroid ringtail possums have not been held in captivity, nor have any been recorded long term in the wild. Judging by close relatives monitored in the wild, an average life expectancy might be as long as 12 to 15 years.
Average lifespan
Status: wild: 4.0 years.
Lemuroid ringtail possums are strictly arboreal. Their habitat is further limited by both elevation and preference for particular tree types. Favoring the high canopies of the rainforest, they are found above 480 meters and 900 meters on the Atherton and Mount Carbine Tablelands, respectively. Furthermore, lemuroid ringtail possums are found only in mature forests, not secondary or regrowth forests.
Range elevation: 900 (high) m.
Average elevation: 480 m.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: rainforest
The range of lemuroid ringtail possums is restricted to the northeastern rainforests of Queensland, Australia. Hemibelideus lemuroides are found in an area of only 300,000 hectares in two rainforests in the Atherton Tablelands and Mount Carbine Tablelands areas.
Biogeographic Regions: australian (Native )
Lemuroid ringtail possums forage, on average, 16 m above the ground. They are almost exclusively folivorous, specializing in low fibrous leaves, with little variation. Lemuroid ringtail possums eat leaves only from a handful of tree species, preferring young foliage. Preferred tree species are Queensland maple (Flindersia brayleyana), brown quandong (Elaeocarpus ruminatus), and bollywood (Litsea leefeana). If there are no young leaves to be eaten they take mature leaves from their preferred trees, as opposed to eating young leaves from another species. Lemuroid ringtail possums eat other parts of trees as well, particularly the flower buds from brown bollywood (Litsea leefeana) and the fleshy covering of yellow walnut (Beilschmiedia bancroftii).
Plant Foods: leaves; wood, bark, or stems; seeds, grains, and nuts; flowers
Primary Diet: herbivore (Folivore )
There are no known positive effects of Hemibelideus lemuroides on humans.
There are no known adverse effects of Hemibelideus lemuroides on humans.
The status of H. lemuroides is stable, but precarious. Populations currently seem healthy but the habitats that they depend on have so far been spared from extensive logging. Lemuroid ringtail possum populations decreased by 97% in secondary forests compared to primary. This is probably because of their reliance on old trees for dens, their reliance on the leaves of only a few, slow-growing tree species, and their preference for high, continuous forest canopies. Any threat to their primary forest habitats will severely threaten their populations.
CITES: no special status
IUCN Red List of Threatened Species: near threatened
Communication among lemuroid ringtail possums is not well understood. When a young possum is separated from its mother, the young cry with a keening squeak. Reports differ when describing the behavior of adults. Some say that adults are silent, while others maintain that adults reply to lost offspring with a haunting howl. There is no record of groups communicating vocally. If an threat is sensed, all lemuroids in the area are alerted without vocalizations. They congregate in a group, back to back, maintaining physical contact with each other.
Both sexes of Hemibelideus lemuroides secrete a cream colored fluid, which they rub over themselves. Secretions, accompanied by a strong musky odor, are stimulated when lemuroids are disturbed or handled. This may be a form of communicating identity, reproductive state, or other factors.
Lemuroid ringtail possums have large, forward facing eyes adapted to night vision. It is assumed that through vision they locate food, predators, and fellow possums.
Communication Channels: visual ; tactile ; acoustic ; chemical
Other Communication Modes: scent marks

Hemibelideus literally translates as "half-glider" ('belideus' being a diminutive form of Petaurus, meaning "glider"). It was once thought that Hemibelideus lemuroides were gliding possums.
Little is known about the mating system of Hemibelideus lemuroides. Adults have a strong, long lasting pair bond. Monogamous couples raise their offspring together, forage for food together, and share a den. The exact duration of the pair bond is unknown, but it lasts well into the period when the offspring finally become autonomous, about 9 months after birth.
Mating System: monogamous
Young are born in early August and crawl into the pouch on the female's underside. The young remains in the pouch until November, drinking milk from the mother. While the mother has two teats in her pouch, only one offspring is reared at a time. After 6 to 7 weeks, the young leave the pouch and ride on the mother’s back for another 6 months, from October to April.
Information about sexual maturity is unknown, but we can look for generalizations among their close relatives. Petauroides volans reach sexual maturity after 2 years, lemuroid ringtail possumss may have a similar pattern.
Breeding interval: Lemuroid ringtail possumss breed once yearly.
Breeding season: Mating probably occurs in mid winter (late June, July).
Range number of offspring: 1 (high) .
Average weaning age: 4 months.
Average time to independence: 6 months.
Average age at sexual or reproductive maturity (female): 2 years.
Average age at sexual or reproductive maturity (male): 2 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous
Average number of offspring: 1.
Parental investment after birth lasts 9 months. The offspring is carried in the mother's pouch for the first 4 months, receiving food and protection. Young Hemibelideus lemuroides are altricial, unable to provide for themselves. The young suckles milk from its mother until it leaves the pouch. Then both parents are active in caring for their young. Lemuroid ringtail possums are social, and the core unit is the adult parents and their single young. Single-family units are often seen foraging with other family groups. Outside of the family, however, there is no hierarchical social structure.
The offspring follow and learn from both parents for another 5 months before gaining independence. During this time, they rarely intentionally leave their parents' side. Both parents spend considerable amounts of time protecting and teaching the offspring. They often remain in close proximity, even when the young have reached adulthood.
Parental Investment: altricial ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Male, Female); pre-independence (Provisioning: Male, Female, Protecting: Male, Female); post-independence association with parents; extended period of juvenile learning

Der Lemuren-Ringbeutler (Hemibelideus lemuroides, Syn.: Hemibelideus cervinus Logman, 1915) ist eine Beutelsäugerart aus der Familie der Ringbeutler (Pseudocheiridae). Er trägt seinen Namen aufgrund der Ähnlichkeiten mit den madagassischen Lemuren.
Das Fell der Lemuren-Ringbeutler ist ausgesprochen dicht und wollig, es ist an der Oberseite in einem dunklen Schokoladenbraun und an der Unterseite gelbgrau gefärbt. Eine seltenere Farbmorphe ist auf dem Rücken cremefarben, ihre Bauchseite ebenfalls gelbgrau. Sie wurde in der Vergangenheit als eigenständige Art beschrieben. Der Schwanz ist bis auf den hinteren Bereich an der Unterseite ebenfalls dicht behaart und kann als Greifschwanz verwendet werden. Der Kopf ist relativ klein, die kurzen Ohren ragen kaum aus dem Fell heraus. Zwischen den Gliedmaßen haben sie angedeutete Flugmembranen, die auf eine enge Verwandtschaft zum Riesengleitbeutler hindeuten. Diese Tiere erreichen eine Kopf-Rumpf-Länge von 31 bis 40 Zentimeter, haben einen 23 bis 38,4 Zentimeter langen Schwanz und ein Gewicht von 810 bis 1170 Gramm.
Lemuren-Ringbeutler leben in zwei kleinen Gebieten in den Feuchttropen von Queensland (Australien). Eine Population lebt zwischen Ingham und Cairns in einer Höhe von etwa 400 Metern über dem Meeresspiegel, die andere, kleinere in einer Höhe von 1100 Metern auf dem Tafelland des Mount Carbine westlich von Mossman.
Lemuren-Ringbeutler sind ausgesprochene Baumbewohner, die sich meist in Höhen von elf bis zwanzig Metern aufhalten, und damit höher als ihre Verwandten, der Grüne Ringbeutler (Pseudochirops archeri) und der Herbert River-Ringbeutler (Pseudochirulus herbertensis). Sie gelten als agile und gute Kletterer und können auch etwa zwei bis drei Meter weit von Baum zu Baum springen. Den Tag verbringen sie in Baumhöhlen schlafend, um in der Nacht auf Nahrungssuche zu gehen. Sie leben oft in kleinen Familiengruppen zusammen (Männchen und Weibchen oder Weibchen mit Nachwuchs), bei der Nahrungsaufnahme schließen sie sich manchmal zu größeren Gruppen (bis zu acht Tiere) zusammen. Ihre Nahrung besteht in erster Linie aus Blättern. Insgesamt sind 37 Arten von Regenwaldbäumen bekannt, deren Blätter sie fressen, vor allem von Lorbeergewächsen, Elaeocarpacen und Rautengewächsen.
Der Beutel der Weibchen enthält zwei Zitzen, trotzdem kommt meist ein einzelnes Jungtier zur Welt. Nach der Geburt verbringt dieses die ersten Lebensmonate im Beutel der Mutter, später reitet es auf ihrem Rücken. Die Geburten finden meist zwischen August und November statt, Jungtiere, die auf dem Rücken der Mutter reiten werden von Oktober bis April gesehen.
Zu den natürlichen Feinden des Lemuren-Ringbeutlers gehören der Amethystpython (Simalia kinghorni), der Rote Buschkauz (Ninox rufa), die Flecken-Rußeule (Tyto multipunctata) und der Riesenbeutelmarder (Dasyurus maculatus).
Der Lemuren-Ringbeutler wurde 1884 durch den norwegischen Zoologen Robert Collett unter dem wissenschaftlichen Namen Phalangista lemuroides beschrieben und noch im gleichen Jahr durch denselben Autor der Gattung Hemibelideus zugeordnet. Die Gattung ist bis heute monotypisch geblieben. Innerhalb der Familie der Ringbeutler (Pseudocheiridae) bildet der Lemuren-Ringbeutler zusammen mit den drei Arten der Riesengleitbeutler (Petauroides) die Unterfamilie Hemibelideinae[1].
Ein Teil ihres Verbreitungsgebietes ist geschützt, dort dürften die Tiere relativ häufig sein, durch Rodungen und Zerstückelung ihres Lebensraumes sind sie in anderen Gebieten selten geworden. Durch Rodungen und Zerstückelung ihres Lebensraumes sind sie besonders bedroht, da sie nicht auf den Erdboden kommen um zwischen verschiedenen Waldfragmenten zu wechseln, nur die Blätter von Bäumen, die für Primärwälder typisch sind, fressen und natürliche, ausreichend große Baumhöhlen benötigen um tagsüber zu schlafen. Die IUCN listet die Art als potenziell gefährdet (Near Threatened).[2]

The lemuroid ringtail possum (Hemibelideus lemuroides), also known as the lemur-like ringtail possum or the brushy-tailed ringtail, is a truly singular member of the ringtail possum group. It was once thought that they were greater gliders (Petauroides volans); Hemibelideus literally translates as "half-glider" (belideus being a diminutive form of Petaurus, meaning "glider").[3] Named for their facial characteristics visually similar to the unrelated primate lemurs, with short snouts, large, forward-facing eyes and small ears, they are similar to other gliding possums in their musculo-skeletal adaptations to accommodate a leaping lifestyle. Their long, prehensile tail is a further adaptation to their arboreal habitat.[3]
It has a bushier tail when compared to other ringtails, and can be distinguished from the greater glider by its lack of gliding membrane and much shorter, hairless ears. It is a social possum, and is found in two main colour forms: the more common brownish-gray form,[3] with a yellowish underbelly, and a rare white form, which occurred in the Daintree Rainforest and was last seen in 2005 in Mount Lewis National Park, and in 2008 believed to have been nearly extinct.[4][5][6]
This possum is found in a small area of only about 300,000 hectares in total, between Ingham and Cairns in Queensland, Australia, and in an isolated population on the Mount Carbine Tableland,[4] both within the Wet Tropics World Heritage Area.[6] They are strictly arboreal and live in the high canopies of mature forests and favour particular tree types, usually found above 480–900 metres in elevation. Body length is 30–38 cm and tail length 30–35 cm, weighing between 810 and 1140 grams.[3]
Stephen Williams, researcher on climate change and biodiversity at the Centre for Tropical Biodiversity and Climate Change at James Cook University, Queensland, stated that none were seen for several years after the heat waves of 2005, when first a few were spotted (three were observed in the Daintree National Park, on Cape York Peninsula in 2009[7]) then increasing numbers as they slowly recovered.[6] Williams said in 2009 that there was no reason to believe the white variant would be impacted more than the brown.[7]
Then the next heatwave in struck in November 2018, when the Cairns region was hit by the highest temperatures since records began – even the highest mountain in the wet tropics reached 39 °C. Many tropical species cannot cope with extreme heat, not having evolved mechanisms to cool their bodies down, according to Williams; they can die from temperatures above 29 degrees. He said that over the past 15 years systematically species have started to disappear from the lower elevations, causing the total populations to decline as they are constrained to smaller areas at higher elevations. This puts pressure on creatures living in the mountain summits such as the lemuroid possum, which have nowhere else to go; the nearest rainforest is 1000 kilometres away.[6]

Hemibelideus lemuroides
Le phalanger lémurien (Hemibelideus lemuroides ; en anglais : Lemur-like Ringtail Possum, ou Lemuroid Ringtail Possum) est un des plus singuliers membre du groupe des possums à queue en anneau australiens. En fait il est beaucoup plus proche du grand planeur (Petauroides volans) que des autres possums.
Hemibelideus lemuroides est la seule espèce du genre Hemibelideus.
Il se distingue des autres possums par sa queue beaucoup plus fournie. Il se distingue du grand planeur par la taille de sa membrane volante qui est plus petite et par ses oreilles dénudées. Il existe sous deux couleurs différentes: la plus commune est d'un brun « chocolat », l'autre, plus rare, blanche que l'on trouvait dans la forêt tropicale de Daintree et que l'on n'a plus vu depuis 2005[1],[2].
On le trouve dans un petit territoire entre Ingham et Cairns dans le Queensland, en Australie. On en trouve une population isolée sur le plateau Carbine[1].

Hemibelideus lemuroides est la seule espèce du genre Hemibelideus.
Il coda ad anello lemuroide (Hemibelideus lemuroides Collett, 1884) è un marsupiale arboricolo della famiglia degli Pseudocheiridi. È l'unica specie del genere Hemibelideus Collett, 1884[2].
Il coda ad anello lemuroide ha una lunghezza testa-corpo di 31,3–52 cm e una coda di 33,5–73 cm; pesa 810-1270 g. Presenta generalmente un manto di colore marrone-cioccolato, tinto di giallo sulle regioni inferiori e di rosso sulla testa. Ha zampe di colore marrone scuro, piedi neri e due anelli chiari attorno agli occhi. La pelliccia è soffice e lanosa, ed è piuttosto folta sulla coda, a eccezione di una chiazza glabra sulla parte inferiore, vicino all'estremità. Questa particolarità aiuta l'animale ad arrampicarsi sugli alberi e gli consente di afferrare i rami con la lunga coda prensile. Le orecchie sono quasi completamente nascoste dal pelo e il muso è breve.
Il coda ad anello lemuroide possiede inoltre piccole frange di pelle ai lati del corpo che vengono aperte quando l'animale salta da un ramo all'altro, consentendogli di planare per distanze molto brevi. Questa insolita caratteristica ha portato alcuni scienziati a ipotizzare che la specie costituisca una sorta di anello di transizione tra gli altri Pseudocheiridi e i Petauridi.
In una zona isolata della foresta del Daintree è presente una rara forma bianca di coda ad anello lemuroide, interamente di colore bianco-crema con riflessi arancio[3][4][5].
Il coda ad anello lemuroide ha abitudini rigorosamente arboricole e notturne; durante la notte conduce vita attiva, effettuando anche salti di due o tre metri da un ramo all'altro. Quando salta, distende le zampe e appiattisce il corpo, utilizzando la coda come un timone. Va spesso in cerca di cibo in piccole unità familiari composte da un maschio, una femmina e un unico piccolo, ma talvolta su un solo albero sono state avvistate aggregazioni anche di otto esemplari. Durante il giorno riposa in cavità degli alberi imbottite di fogliame.
Il coda ad anelli lemuroide è folivoro, e si nutre quasi interamente di foglie. Predilige le giovani foglioline di acero del Queensland (Flindersia brayleyana) e di quandong bruno (Elaeocarpus coorangooloo), ma mangia anche boccioli di fiori e la polpa che ricopre alcuni semi.
La stagione degli amori va da agosto a novembre, ma le femmine partoriscono generalmente il loro unico piccolo agli inizi di agosto. Il piccolo rimane nel marsupio materno per sei o sette settimane, nutrendosi del latte della madre. Dopo aver lasciato il marsupio, viene trasportato in giro sul dorso della madre per circa sei mesi, da novembre ad aprile, e raggiunge la piena indipendenza a circa nove mesi di età.
Il coda ad anello lemuroide è presente solamente in due località distinte del Queensland settentrionale: una compresa tra Ingham e Cairns, a circa 450 m di quota, e l'altra, più piccola, sul tavolato del monte Carbine, a ovest di Mossman, a circa 1100 m di quota[3]. Abita le fredde e umide foreste pluviali, prediligendo le aree interne a quelle marginali.
La specie è minacciata soprattutto dal riscaldamento climatico globale. Infatti l'esposizione prolungata a più di 30 °C provoca in questi animali la perdita del controllo della termoregolazione, causandone la morte. La specie è particolarmente vulnerabile anche perché, vivendo già sulle cime dei monti, non può trovare rifugio dal calore spostandosi verso quote più elevate.
Un'altra minaccia è costituita dalla deforestazione e dalla distruzione dell'habitat. Avendo abitudini arboricole, non può spostarsi da una chiazza di foresta all'altra, e nelle zone dove il suo habitat è stato danneggiato la popolazione è diminuita del 97%. La IUCN classifica H. lemuroides tra le specie prossime alla minaccia (Near Threatened)[1].

De Queenslandkoeskoes (Hemibelideus lemuroides) is een klimbuideldier uit de familie der kleine koeskoezen (Pseudocheiridae). Het is de enige soort van het geslacht, dat eerder tot Pseudocheirus is gerekend, maar waarschijnlijk nauwer verwant is aan Petauroides, waarmee het de onderfamilie Hemibelideinae vormt.
De bovenkant van het lichaam is chocoladebruin, de onderkant grijsbruin. Sommige dieren zijn volledig wit. De antracietgrijze, borstelige staart is zeer harig en heeft een kale punt. Die staart wordt gebruikt om tijdens een sprong te sturen en zich aan takken vast te grijpen. De kop-romplengte bedraagt 320 tot 400 mm, de staartlengte 300 tot 370 mm en het gewicht 750 tot 1100 g.
Deze soort is 's nachts actief, leeft in bomen en eet bladeren, bloemen en fruit. Het is een sociale soort, die in paartjes of familiegroepen leeft. Tussen augustus en november wordt een enkel jong geboren, dat na 6 tot 7 weken de buidel verlaat.
Deze soort komt voor in de regenwouden van Noordoost-Queensland, op minstens 450 m hoogte, tussen Ingham en Cairns, met een geïsoleerde populatie op meer dan 1100 m hoogte op het Carbine Tableland.

Vakoveverica lemurovitá (lat. Hemibelideus lemuroides) je druh kengury z čeľade Pseudocheiridae. Pripomína tvarom, a telesnými proporciami poloopice lemury.
Hemibelideus lemuroides är ett pungdjur i familjen ringsvanspungråttor och den enda arten i släktet Hemibelideus.[2] Den påminner i utseende om lemurer men är inte släkt med dessa.
Djurets päls är mycket tät och ullig. Den är på ovansidan mörkt gråbrun och på undersidan gulgrå. Svansen är lite längre än övriga kroppen och tätt täckt med hår, med undantag av ett ställe vid spetsens undersida. Svansen används som gripverktyg.[3] Huvudet är jämförelsevis litet samt något rödaktig och de små öronen är nästan gömda i pälsen. Mellan extremiteterna har den anlag till en flygmembran som hänvisar till släktskapet med arten jätteflygfalang.[3] Kroppslängden utan svans ligger mellan 31 och 35 centimeter. Vikten varierar mellan 800 och 1300 gram.[3]
Arten lever i regnskogar i nordöstra Queensland, Australien. Området kännetecknas av bergstrakter som är minst 450 meter höga. Den vistas nästan alltid i träd och har bra förmåga att klättra och hoppa.[3] Hemibelideus lemuroides vilar på dagen i trädets håligheter och letar på natten efter föda. Ofta förekommer familjegrupper (hanne och hona eller bara hona med ungdjur). När de letar efter föda bildar de ibland större grupper med upp till åtta individer. Födan utgörs främst av blad.[3] Dessutom äter arten blommor, knopp och nöt av trädet Beilschmiedia bancroftii.[4]
I honans pung (marsupium) finns två spenar men vanligen föds bara ett ungdjur åt gången. Ungen visats de första månaderna i pungen och klamrar sig senare fast på moderns rygg.[3]
Artens naturliga fiender utgörs av rutpyton (Morelia spilota) och rödbrun spökuggla (Ninox rufa).[4]
Vissa delar av utbredningsområdet är skyddszon och där uppskattas ett större bestånd. I andra regioner blev de sällsynta på grund av förstöring av levnadsområdet. IUCN listar arten som nära hotad (Near Threatened).[1]
Hemibelideus lemuroides är ett pungdjur i familjen ringsvanspungråttor och den enda arten i släktet Hemibelideus. Den påminner i utseende om lemurer men är inte släkt med dessa.

여우원숭이반지꼬리주머니쥐(Hemibelideus lemuroides)는 반지꼬리주머니쥐과에 속하는 유대류의 일종이다. 오스트레일리아 퀸즐랜드주 잉햄과 케언스 사이의 좁은 지역에서 발견된다. 카빈 테이블랜드에서도 고립된 개체군으로 발견된다.[3] 다른 반지꼬리주머니쥐와 비교하여 붓꼬리에 털이 더 무성하며, 활강막이 없고 귀가 더 짧고 털이 없어서 주머니날다람쥐와 구별할 수 있다. 무리 생활을 하며, 색에 따라 두 부류가 발견된다. 가장 흔한 부류는 초콜렛 갈색을 띠며, 나머지는 드물게 발견되는 흰색을 띠는 부류로 데인트리 우림에서 서식하며 2005년에 마지막으로 관찰되었다.[3][4] 그러나 2009년 갈색을 띠는 부류가 케이프 요크의 데인트리 국립공원에서 발견되었다.[5]
