The northern broad-nosed bat (Scotorepens sanborni) is a species of the vespertilionid family of microbats. It can be found in northern Australia, Timor-Leste, and Papua New Guinea.
The species was first described by Ellis Le Geyt Troughton in 1937, allying to a genus Scoteinus. [2] The taxon was assigned to the rank of subspecies, as Scotorepens balstoni sanborni, but recognised as a species following a revision by Darrell Kitchener. The type locality in the Milne Bay region of Papua New Guinea. [3] The author nominated the specific epithet sanborni in recognition of the works of Colin C. Sanborn, a curator at the Field Museum of Natural History and appreciation for his accommodation in Chicago while researching the mammals of Oceania. [2]
The two populations found in Australia are reported to be genetically distinguishable. [1]
A species of Scotorepens , closely resembling the widespread 'inland' or 'western' species S. balstoni excepting its slightly larger size. The muzzle is hairless and has prominent glands that are characteristic of the genus. The pelage colour is variable among individuals, the hair over the upper-parts is a uniform sandy to tawny olive and darker than the bi-coloured ventral fur, which is a pale greyish brown with whitish tips. [4]
The measurements of the geographical separated Australian populations are distinguished as those from the northwest and another from Queensland, as with S. balstoni the size of individuals becomes greater in the east and north of the range. The size and weight range of the Kimberley and Top End group is 28 to 34 millimetres for the forearm, an average of 31 mm; head and body combined is 37 to 48 mm; tail length is 27–36 mm; ear length is an average of 10 mm, ranging from 9–12 mmm; the average weight of the range 5.7 to 7.3 grams is 6.5 g. Those in Queensland are somewhat larger, a forearm length averaging 33 mm, for a range of 31–36 mm; head and body is 40–52 mm; tail ranges in length from 29 to 39 mm, ear length from 10 to 13 mm. The weight range of the eastern populous is 5.7 to 9.1 grams, an average of 7.3 g. [4]
A widely distributed species whose range extends across Timor-Leste, Papua New Guinea and the northern coast of Australia.
There are two geographically separated populations in the northern parts of Australia. One is located from the western Top End to the Kimberley region in the northwest of the continent, occurring in coastal and sub-coastal wooded regions of mangrove forest and near waterways. Another population is located north of Rockhampton, inland from the coast to the Cape York peninsula, occurring at heathlands, open woodland and monsoonal forest. [4]
The daytimes roosts are usually sited in tree hollows, although buildings have also be used. They are often observed foraging for smaller flying insects such as midges and mosquitoes over open water. The species reproduces during September to November. [4]
The long-tongued nectar bat, also known as the northern blossom bat, honey nectar bat, least blossom-bat, dagger-toothed long-nosed fruit bat, and lesser long-tongued fruit bat, is a species of megabat. M. minimus is one of the smallest species in the family Pteropodidae, with an average length of 60–85 mm. It has a reddish-brown colouring with relatively long hair compared to the other species. The hair on the abdomen is a lighter colour, and a dark brown stripe runs bilaterally down the top of the head and back.
The red-cheeked dunnart is so called because of the distinctive red hair on its cheek. It is an Australasian marsupial. Its total length is 167–270 mm; its average body length is 80–135 mm with a tail of 87–135 mm. Ear length is 12–13 mm. Its weight varies between 18 and 75 grams. Its tail is thin and pale pink.
Gould's long-eared bat is a microbat found in southern regions of Australia. It occurs in eastern Australia, from Queensland to Victoria, and in a smaller isolated range in the south-west of Western Australia.
The pale field rat is a small rat endemic to Australia. It is a nocturnal and herbivorous rodent that resides throughout the day in shallow burrows made in loose sand. Once widespread, the range has become greatly reduced and it is restricted to the grasslands, sedges, and cane-fields at the north and east of the continent. The fur is an attractive yellow-brown colour, with grey or cream at the underside. This medium-sized rat has a tail shorter than its body.
The western or inland broad-nosed bat is a species of vesper bat. They are endemic to Australia and widespread throughout the inland, especially in arid and semi-arid regions. This insectivorous microbat, measuring 12 centimetres (4.7 in) in length, roosts in tree hollows during the day and forages over woodland and water at night.
Rüppell's or the greater broad-nosed bat is a species of vespertilionid microbat found in eastern Australia.
The eastern broad-nosed bat or Orion broad-nosed bat is a species of vespertilionid bat. It is found only in Australia, east of the Great Dividing Range, from about Rockhampton to Melbourne, with a small isolated population on the Atherton Tablelands.
The inland forest bat is a vespertilionid bat that occurs in central and arid regions in Australia. They were first described in 1987, published in a review of poorly surveyed microbat populations. A tiny flying mammal, whose body is around twelve millimetres (½ inch) long, that occupies small cavities in trees and buildings while roosting. The nocturnal activity is foraging for insects, typically moths.
The northern cave bat is a vespertilionid bat that occurs in most of Australia.
The yellow-lipped cave bat is a vespertilionid bat which only occurs in the Kimberley region of northwest Australia. The bat was first captured at Tunnel Creek in 1958 and a description published nearly twenty years later. Aside from observations of their physical characteristics, a preference for caves, and hunting insects over streams, little is known of the species.
Finlayson's cave bat is a species of vespertilionid bat found only in Australia.
Xeromys myoides, also known as the water mouse, marine mouse, mangrove mouse, false water rat, manngay and yirrkoo, is a species of rodent native to waterways of Australia and Papua New Guinea.
The Papuan sheath-tailed bat is a species of bat in the family Emballonuridae which occurs at the Cape York Peninsula and New Guinea. The poorly known species hunts in open forests for night flying insects.
The rufous owl, also known as the rufous boobook, is a species of owl in the family Strigidae. It was described in 1846 by John Gould, an English ornithologist. Its common name reflects the rufous-coloured feathers that these owls are covered with in adulthood. While it is uncommon, the species has a wide range, including Australia, Indonesia, and Papua New Guinea.
The smaller horseshoe bat is a species of bat in the family Rhinolophidae. It is found in Australia and Papua New Guinea.
Scotorepens is a genus of bats within the Vespertilionidae family. Species within this genus are widely distributed across Australia and to the north at Papua New Guinea and Indonesia.
The big-eared flying fox is a species of bat in the family Pteropodidae, larger bats who subsist largely on fruits. The species is distributed across a range in Indonesia, Papua New Guinea and islands nearing the Cape York peninsula at the northeast of Australia, at elevations less than 500 metres and often in coastal mangroves.
Nyctophilus daedalus is a species of bat in the family Vespertilionidae, a flying mammal endemic to northern Australia. They are also referred to as the pallid long-eared bat or northern long-eared bat.
Ozimops cobourgianus is a species of molossid bat, insectivorous flying mammals known as freetail bats, which are found in north and west coastal regions of Australia. First described in 1959, the group were later recognised as species Mormopterus cobourgianus and soon placed with a new genus. They are associated with mangrove habitat and roost in the hollows of those trees, and known to seek food there and in eucalypt or melaleuca woodland or other coastal habitat. A smaller bat of genus Ozimops, O. cobourgianus are around fifty millimetres long and weigh six to ten grams. Little is known of their habits.
