The orbiculus leaf-nosed bat (Hipposideros orbiculus), also known as the orbiculus roundleaf bat and small disc roundleaf bat, is a species of bat from the family Hipposideridae. The species has been found on the island of Sumatra in Indonesia and on peninsular Malaysia.[2]
The orbiculus leaf-nosed bat was described as a new species in 1999.[3] The holotype had been collected in Abai Siat, which is southeast of Kota Bharu on the Indonesian island of Sumatra.[1] It is cryptic species with the Ridley's leaf-nosed bat, though the two can be differentiated based on their echolocation characteristics: the frequencies of the two species' calls differ by 19 kHz.[4]
Its forearm length is 46.15–48.50 mm (1.817–1.909 in). Its tail is 26.2–34.2 mm (1.03–1.35 in) long and its ears are 20.6–23.6 mm (0.81–0.93 in) long. It echolocates at around 80 kHz.[5]
The orbiculus leaf-nosed bat has been documented in three areas: West Sumatra of Indonesia, near Rawang, Selangor of Malaysia, and Sungkai Wildlife Forest Reserve, which is also in Malaysia.[6]
As of 2015, the orbiculus leaf-nosed bat ess listed as a vulnerable species on the IUCN Red List because of its small extent of occurrence and continuing decline of the extent and quality of its habitat, as well as its population. It had previously been listed as an endangered species but was reevaluated because its extent of occurrence was recalculated to 20,345 km2 (7,855 sq mi).[1][7] The orbiculus leaf-nosed bat is a terrestrial species that prefers lowland rainforests, and its habitat is degrading due to logging, agriculture, infrastructure development, plantations, and forest fire.[1]

Hipposideros orbiculus (Francis, Kock, & Habersetzer, 1999) è un pipistrello della famiglia degli Ipposideridi diffuso nell'Ecozona orientale.[1][2]
Pipistrello di piccole dimensioni, con la lunghezza dell'avambraccio tra 46 e 49 mm, la lunghezza della coda tra 26 e 34 mm, la lunghezza delle orecchie tra 20 e 23,5 mm e un peso fino a 10,3 g.[3]
Il colore generale del corpo è marrone scuro. Le orecchie sono grandi, scure e arrotondate. La foglia nasale presenta una porzione anteriore priva di fogliette supplementari, un setto nasale ingrandito e di forma discoidale che copre quasi completamente le narici, una porzione posteriore con tre setti verticali che la dividono in quattro celle. Le membrane alari sono scure. La coda è lunga e si estende leggermente oltre l'ampio uropatagio.
Emette ultrasuoni ad alto ciclo di lavoro sotto forma di impulsi a frequenza costante di 80 Khz.
Si nutre di insetti.
Questa specie è diffusa nella Penisola malese e sull'isola di Sumatra.
Vive nelle foreste pluviali di pianura.
La IUCN Red List, considerato l'areale limitato a solo due località e il continuo declino nell'estensione e nella qualità del proprio habitat, classifica H.orbiculus come specie in pericolo (EN).[1]

오르비쿨루스잎코박쥐 또는 오르비쿨루스둥근잎박쥐(Hipposideros orbiculus)는 잎코박쥐과에 속하는 박쥐의 일종이다. 인도네시아 수마트라섬과 말레이반도에서 발견된다.[2] 오르비쿨루스잎코박쥐는 차지하는 서식지의 크기가 작고, 현존하는 서식지의 질이 떨어지고 있으며 개체수가 감소하기 때문에 IUCN 적색 목록에서 "멸종위기종"으로 등록되었다.[1] 서식지로 저지대 우림을 선호하며, 서식지는 벌목과 농업, 기반 시설 개발과 농장, 산불 때문에 파괴되고 있다.[1]
