Taxonomy
A single male specimen was collected in 1874 and deposited at the
The description for this was published by George Edward Dobson in 1878, in a revision of chiropteran specimens held at the museum.[2] Further details were provided when the specimen was again examined in 1912.[4] Since that record, no further documentation is known of this species;[5] the specimen is still located at BMNH. The description was re-evaluated in the late twentieth century, and recognition as a species is maintained in the third edition of The Mammals of Australia (National Photographic Index of Australian Wildlife, 2008).[6][1] Speculation on the taxon includes the proposition the specimen may be an undiagnosed vagrant of another species.[1]
Description
A smaller species of genus Pteropus, the weight estimated to be around 200 g (7.1 oz). The length of the head and body combined is approximately 210 mm (8.3 in), the forearm of the single specimen is 118 mm (4.6 in). Fur colour of this macrobat is uniform across the body, a golden shade of brown.[7]
The first description notes the form of the ears, comparing the specimen to those of Pteropus keraudrenii (
The species bears no resemblance to the Australian
Distribution and habitat
The presumed distribution is uncertain, and the type location given with the only specimen has been considered questionable. Nominally the range is cited as "Percy Island", long presumed to be part of an offshore island group known as the Percy Isles that form part of the Northumberland Islands.[3] The exact island of the collection has never been determined.[1] The record of the species was provided by the amateur collector, following a trend amongst British aristocratic explorers for assembling or trading specimen collections that were returned to England.[3]
A colony of bats at the island is reported after the collection date, without physical evidence, no later survey has identified a similar megabat camp at the location.[1] Several possibilities have been proposed to account for this species, these include a colony blown to the islands in a cyclone, which became extinct shortly after, or that the locality of the collection was in error.[3] The location might be confirmed by skeletal remains at the purported camp or by discovery of nearby populations.[1]
