Ozimops halli, also referred to as the Cape York free-tailed bat, is a species of molossid bat found at the Cape York Peninsula in Australia.

Taxonomy

A species of genus Ozimops , both taxa emerging in the publication of new species and generic combinations of mostly Australian molossid bats. Prior to this, an analysis of populations in the regions in 1988 had identified this group as 'Mormopterus species 5 (populations S and T)'. [1] [3] Specimens have previously been described as Mormopterus ridei , at least in part, or other uncertainty in paraphyletic groups once referred to as the planiceps complex. [2] The generic combination of this species was inferred by the elevation of a subgenus to genus Ozimops. [3] The first publication of the species was in 2014, allying it to a subgenus of the group under revision as Mormopterus (Ozimops) halli. [3]

The common names also include Cape York free-tailed bat.

The type specimen, a male, was obtained on 7 November 2006 by four collectors [lower-alpha 1] at the Ironbark Dam in the Oyala Thumotang National Park. [2] [3] The epithet refers to a conservation advocate of bats, Leslie Hall, which the authors gave in honour of his contribution to chiropteran research. [2]

Description

Ozimops lumsdenae is a larger microbat, insectivorous flying mammals, which is robust in appearance and the second largest of its genus. The length of the forearm is 31 to 35 millimetres and weight is around 9 grams. The colour of the pelage is a rich or orange brown, the frequent contrast of front and back related species is indistinct and O. halli is almost uniform in colour. There is a yellowish hue in hair at the side of the neck. The skin is very dark brown, evident at the snout, ears and the patagium across the wings. [2]

Distribution and habitat

The records for Ozimops halli, which number around a dozen, are in separate localities in the north of Queensland. The known records are separated by around 500 kilometres, in a region poorly surveyed for bat populations, and it may be widespread or occur in isolated colonies. The established range is within or nearby to the type location, the conservation area Oyala Thumotang NP. [1] Surveys of the distribution range would be assisted by analysis of the characteristics of the species echolocation call. [2]

The species is known from specimens captured by mist nets laid near bodies of water in open vegetation of eucalypt woodlands. They are presumed to inhabit tree hollows as this is the habit of sympatric species and those in similar habitat. [1]

Ecology

The species may occur with others of the genus Ozimops, it is recorded in sympatry with Ozimops ridei and probably O. lumsdenae . [2]

The conservation status of Ozimops halli is data deficient at the entry in the IUCN redlist, which notes the stability of the population as unknown. [1]

<i>Mormopterus</i> Genus of bats

Mormopterus is a genus of molossid microchiropterans, small flying mammals referred to as free-tailed bats. The genus has been the subject of several revisions, and the diversity of taxa centred on Australia were separated to a new genus Ozimops, and two monotypic genera, Setirostris and Micronomus. The species of Mormopterus, in this stricter sense, are only found in areas outside of Australia and West Papua.

<i>Micronomus</i> Species of bat

Micronomus norfolkensis is a species of molossid bat, a family of flying mammals. The bat is endemic to Australia, where it occurs from southeastern Queensland to eastern New South Wales. They are the sole species of genus Micronomus and referred to by variations on east-coast free-tailed bat.

<i>Ozimops beccarii</i> Species of bat

Beccari's free-tailed bat is a species of bat in the free-tailed bat family Molossidae found to Indonesia and Papua New Guinea. It can be found in several habitat types, including savanna, tropical moist forest, and fragmented and urban habitat. It roosts in trees, caves, and buildings in small colonies. This is a common species which is not considered to be threatened. The names Beccari's free-tailed bat or Beccari's mastiff bat once applied to populations in Australia.

Kalinowski's mastiff bat is a species of bat in the family Molossidae, the free-tailed bats. It is native to Peru and northern Chile. Relatively little is known about the species, but it is thought to be common in its range. It is sometimes seen in urban areas. Molecular sequencing data indicates that the closest relatives of M. kalinowski are members of another genus, Nyctinomops.

<i>Setirostris</i> Genus of bats

Setirostris eleryi is a species of small insectivorous bat found in inland eastern Australia. It is the sole species of the molossid genus Setirostris, a name that refers to the coarse bristles on their faces.

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.
