El ratpenat nasofoliat bicolor (Hipposideros bicolor) és una espècie de ratpenat de la família dels hiposidèrids. Viu a Indonèsia, Malàisia, Filipines, Tailàndia i Timor Oriental. El seu hàbitat natural és el bosc primari, no és comú en les àrees forestals pertorbades. No hi ha cap amenaça significativa per a la supervivència d'aquesta espècie, tot i que està afectada per ser sensible a la desforestació.[1]

The bicolored roundleaf bat (Hipposideros bicolor) is a species of bat in the family Hipposideridae found in Indonesia, Malaysia, the Philippines, Thailand, and Timor-Leste.[1] This bat inhabits caves, rock crevices and tunnels among lowland forests. They roost in large numbers and consume mostly small winged insects.[2] Their navigation and hunting skills come from the use of echolocation. Its leafnose is used to release ultrasonic shouts to distinguish its surroundings. Echolocation is also used to distinguish other species based on their wingbeat and size.[3] The habitat of this bat decides the color of its fur. Bleaching fumes of a cave environment will cause an orange colored fur. Those who inhabit a well-ventilated roost will be a light brown color.[4]
It was described as a new species in 1834 by Dutch zoologist Coenraad Jacob Temminck. Temminck placed it in the genus Rhinolophus with a binomial of R. bicolor.[5] The bicolored leafnose bat has four subspecies: Hipposideros bicolor atrox, Hipposideros bicolor major, Hipposideros bicolor bicolor and Hipposideros bicolor erigens.[4]
In West Malaysia, researchers have found two different groups of bicolored roundleaf bats. These seemingly identical groups are distinguished by their size and echolocation frequency. The first group has a more rounded wingtip due to its smaller weight and shorter wider wing. It also has an echolocation call between 127.0 and 134.4 kilohertz. The second group has a smaller tibia length but weighs more with larger wings. Their echolocation call ranges from 138.0 to 144.0 kilohertz. Researchers conclude that the first group's body composition may be more suited for better flight agility and hunting in cluttered spaces.[3]
The bicolored roundleaf bat is found in Southeast Asia where its range includes Indonesia, Malaysia, the Philippines, Thailand, and Timor-Leste. It has been documented at elevations up to 600 m (2,000 ft) above sea level.[1] Hipposideros bicolor atrox is documented in southern Thailand to Sumatra. Hipposideros bicolor major located in Enggano Islands and Nias. Hipposideros bicolor bicolor inhabits in Java stretching to the Lesser Sunda Islands and Borneo. Hipposideros bicolor erigens lives solely in the Philippines.[4]
Roosting in groups of up to 150 bats, the bicolored leafnose bat must have darkness and high humidity. They are known to roost in environments that have a constant temperature several degrees cooler than the surrounding areas.[3] Though they prefer to live in forest, they will not dwell in an area that has been disturbed or diminished by humans.[4]
As of 2020, it is evaluated as a least-concern species by the IUCN—its lowest conservation priority. It meets the criteria for this classification because it has a wide geographic range; its range includes protected areas; and it is considered locally common.[1] Despite its wide geographic range, the bicolored leafnose bat is extremely sensitive to habitat loss via deforestation. Deforestation is rapidly growing due to increased demand for residential development and agricultural land for oil palm.[3] Palm oil is derived from the oil palm and is used in detergent, lipstick and margarine. Palm oil is exported primarily by Malaysia and Indonesia producing 88 percent of the world's supply.[4] WWF has led collaboration with other large retailers of palm oil to agree to only use land that has not been subjected to deforestation.[2]

Hipposideros bicolor (Temminck, 1834) è un pipistrello della famiglia degli Ipposideridi diffuso nell'Ecozona orientale.[1][2]
Pipistrello di piccole dimensioni, con la lunghezza totale tra 78 e 86 mm, la lunghezza dell'avambraccio tra 42 e 48 mm, la lunghezza della coda tra 31 e 33 mm, la lunghezza del piede tra 7 e 9 mm, la lunghezza delle orecchie tra 19 e 20 mm e un peso fino a 10,2 g.[3]
La pelliccia è lunga. Le parti dorsali variano dal marrone al bruno-grigiastro, con la base dei peli biancastra, mentre le parti ventrali giallo-biancastre. È presente una fase completamente arancione. La foglia nasale presenta una porzione anteriore piccola, bruno-rosata, di forma quadrata e senza fogliette supplementari laterali, un setto nasale triangolare, largo alla base e più stretto tra le narici, leggermente rigonfio e separato lateralmente da solchi profondi, una porzione intermedia liscia, una porzione posteriore con il margine superiore semi-circolare e provvista di tre setti che la dividono in quattro celle indistinte. Le orecchie sono grandi, arrotondate, con il margine anteriore fortemente convesso e con l'antitrago provvisto di una piega interna. Le membrane alari sono marroni. La coda è lunga e si estende leggermente oltre l'ampio uropatagio. Il primo premolare superiore è piccolo e situato fuori la linea alveolare.
Emette ultrasuoni ad alto ciclo di lavoro con impulsi a frequenza costante. Esistono due forme criptiche differenziate dall'emissione degli ultrasuoni. La prima emette a 127-134 kHz, mentre la seconda a 138-144 kHz.
Si rifugia in gruppi da 10 a 250 individui nelle case, grotte o in tane di altri animali come volpi e istrici. I due sessi convivono sebbene i maschi siano sempre in numero doppio rispetto alle femmine.
Si nutre di insetti con il corpo molle come le termiti.
Le nascite avvengono in aprile e vengono trasportati dalle madri aggrappati alle false mammelle inguinali finché non raggiungono la maturità.
Questa specie è diffusa nella Penisola malese, in Indonesia da Sumatra alle Isole Tanimbar e in alcune delle Isole Filippine.
Vive nelle foreste primarie e meno frequentemente in aree disturbate fino a 620 metri di altitudine.
Sono state riconosciute 7 sottospecie:
La popolazione delle isole di Sumbawa, Sumba e Flores non è stata assegnata ancora a nessuna sottospecie.
La IUCN Red List, considerato il vasto areale e la presenza in diverse aree protette , classifica H.bicolor come specie a rischio minimo (LC).[1]

Hipposideros bicolor is een vleermuis uit het geslacht Hipposideros.
Deze soort komt voor van Zuid-Thailand, Laos en Vietnam tot de Filipijnen, Borneo, Java en de Kleine Soenda-eilanden.[2] Deze soort bevat in haar huidige definitie waarschijnlijk meerdere soorten; zo zijn er in een Maleisische populatie twee soorten gevonden die verschillen in de toonhoogte die ze gebruiken voor echolocatie.[2][3] Populaties van soorten als H. hypophyllus, H. pomona en H. macrobullatus werden voorheen ook tot deze soort gerekend. Ook andere soorten uit de zogenaamde H. bicolor-groep zijn wel tot H. bicolor gerekend (zoals H. ater).[2] In de Filipijnen is de soort alleen gevonden op Luzon en Mindoro.[4]

Hipposideros bicolor[2][3] är en fladdermusart som först beskrevs av Coenraad Jacob Temminck 1834. Hipposideros bicolor ingår i släktet Hipposideros och familjen rundbladnäsor.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1] Inga underarter finns listade i Catalogue of Life.[4] Wilson & Reeder (2005) skiljer mellan 7 underarter.[2]
Denna fladdermus förekommer i Sydostasien från södra Malackahalvön över Borneo och Sumatra till Filippinerna och till Timor. En liten avskilda population finns på fastlandet i södra Thailand. Arten lever i låglandet och i kulliga områden upp till 600 meter över havet. Hipposideros bicolor vilar i grottor och har ursprungliga skogar som habitat.[1]
