The Bornean woolly horseshoe bat or Proconsul's horseshoe bat (Rhinolophus proconsulis) is an endangered species of horseshoe bat found on Borneo. Though it was discovered in 1959, it was not recognized as a distinct species until 2013.

Taxonomy and etymology

This bat was initially described in 1959 from specimens in Borneo as a subspecies of the arcuate horseshoe bat and given the name Rhinolophus arcuatus proconsulis. The author of the 1959 paper, British mammalogist John Edwards Hill, stated that the subspecies was similar in appearance to R. arcuatus, with the exception of its larger body and skull size. [2] Hill later published that a population of R. a. proconsulis was on Sulawesi as well. [3] Authors of a 2013 paper determined that the two populations of R. a. proconsulis on Borneo and Sulawesi were each cryptic species.

They elevated the Borneo population to species rank, R. proconsulis, on the basis of morphological data. The Sulawesi "R. a. procunsulis" was also elevated to species rank in the 2013 paper; it is now called Rhinolophus belligerator . Like the arcuate horseshoe bat, R. proconsulis is placed in the euryotis species group of the horseshoe bat genus. [4]

Its species name proconsulis is derived from Latin "proconsul", meaning "a man who became governor of a province or a military commander following a term as consul." Hill chose this species name "in honour of the Office of H.M. Governor of the Colony of Sarawak, which, having succeeded the hereditary Rajahs, often honoured in this way, has not as far as I am aware yet inspired such a name." [2]

Description

The fur on its back is dark brown; the bases of the hairs on the back are grayish. Fur on the ventral surface is pale brown. Its forearm is 46.8–48.3 mm (1.84–1.90 in) long. Its horseshoe is 9.3–9.7 mm (0.37–0.38 in) long. [2]

Range and habitat

It is known from nine localities in three locations. It has been documented in six caves in Sarawak, Malaysia, two sites in Central Kalimantan, Indonesia, and one site in East Kalimantan, Indonesia. During the day, it roosts in limestone caves. [1] As a cave dweller, it differs ecologically from its relative Rhinolophus arcuatus , which lives in forests. [4]

Conservation

It is currently evaluated as endangered by the IUCN. [1] Caves in Borneo are threatened by disturbance via guano mining, ecotourism, and collecting nests of edible-nest swiftlets. Palm oil plantations and cocoa plantations are resulting in the loss of foraging habitat for insectivorous bats. [5]

Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, Rhinolophus, which has about 106 species, the extinct genus Palaeonycteris has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania.

<span class="mw-page-title-main">Madura horseshoe bat</span> Species of bat

The Madura horseshoe bat is a species of bat from the family Rhinolophidae. Current taxonomy treats the Madura horseshoe bat as a species separate of the Sulawesi horseshoe bat and not including parvus, but Csorba et al. (2003) recognizes both as subspecies of the Sulawesi horseshoe bat. It is known only from seven specimens from Madura Island and the Kangean Islands in Indonesia, and its type locality is Soemenep, Madura Island. The species is listed as Vulnerable on the IUCN Red List, and it suffers from habitat loss due to limestone excavation and deforestation for logging and agriculture in its habitat. It is also unknown whether or not the Madura horseshoe bat lives in any protected areas. The species is cave-roosting and most likely independent of water, foraging in primary forest.
