Taxonomy
.
Taphozous troughtoni
Tate, 1952
,
“
Rifle Creek, Mt. Isa, northwest
Queensland
,”
Australia
.
Taphozous troughtoni
is in the subgenus
Taphozous
.
It was considered ajunior synonym of
T georgianus
,
but. T. Chimimba and D. J. Kitchener in 1991 raised
it
to a distinct species. Monotypic.
Distribution.
NE Australia endemic, in WC, C & E Queensland.
Descriptive
notes.
Head-body
79-4-86-3 mm, tail 31-5-36-9 mm, ear 22-4-27-1 mm, hindfoot 9-8-10-3 mm, forearm 73-76 mm; weight. 20-29 g. Dorsum of Troughton’s Sheath-tailed Bat is predominately olive brown, with pale mouse-gray guard hairs. Venter surface hairs are
olive-brown
from chin to shoulders and posteriorly dark yellow-brown, with guard hairs of pale mouse-gray. Uropatagium close to abdomen is heavily furred. Throat pouches are absent, and radio-metacarpal sacs are present in both sexes. Skin of rhinarium, wings, uropatagium, lips, face, and tragus are fuscous (pale yellow).
Habitat
. Wide variety of habitats and bioregions of interior Queensland.
Food and Feeding
.
Troughton’s Sheath-tailed Bats forage for
insects
well above tree canopies and high over open habitats. Large, high-flying grasshoppers are preferred food items and often taken back to cave roosts to eat.
Breeding
. No information.
Activity patterns.
Troughton’s Sheath-tailed Bat roosts in caves, mines and tunnels, rock crevices, and
rocky
escarpments. Echolocation call is less than 25 kHz and distinguishes it from the Common Sheath-tailed Bat (.
georgianus
)
where they
co-occur
.
Movements, Home range and Social organization.
Large colonies of Troughton’s Sheath-tailed Bat can be found in landscapes with abundant
rocky
outcrops, especially in tower karst. Colony size might be limited by roosting structures, especially in more arid areas where there are few caves deep enough to support large colonies.
Status
and Conservation
. Classified as Least Concern on
TheIUCNRed List.
Troughton’s Sheath-tailed Bat has a large distribution and
presumably
large and stable overall population, uses a wide variety of habitats, occurs in protected areas, and does not face significant threats. It was originally recorded only from a small area in the Mount Isa Inland bioregion of Queensland, but recent studies based on isozymes and echolocation calls extend distribution further east throughout much of interior and near coastal region of central Queensland, formerly attributed to the Common Sheathtailed Bat.
Recent
reports of absence of Troughton’s Sheath-tailed Bat in western parts of its distribution require additional verification, possibly leading to re-evaluation of its conservation status after taxonomic issues are clarified.
