Scotorepens greyii és una espècie de ratpenat de la família dels vespertiliònids. Viu a Austràlia. El seu hàbitat natural és prop de masses d'aigua dins dels boscos oberts i plans àrids. Es refugia en colònies d'uns pocs individus fins a uns vint animals en buits dels arbres, edificis en desús i altres estructures disponibles. No hi ha cap amenaça significativa per a la supervivència d'aquesta espècie.[1]

The little broad-nosed bat (Scotorepens greyii) (pronounced skoh’-toh-rep’-enz grey’-ee-ee’) translates to "Grey’s darkness creeper".[2] Sometimes called Grey’s broad-nosed after the third governor of South Australia, Sir John Edward Grey.[2] It is a species of vesper bat, which is one of the largest and best-known family of bats. They are endemic to Australia, are insectivores and have a broad range within the mainland, mainly in hot arid areas but also found in tropical rainforests.[3][4]
Scotorepens greyii individuals have a slender body shape, a broad square muzzle when viewed from above and have varied fur colouring. Fur ranges from brown to grey-brown on the back, with the base of the hairs being lighter than the tips; the belly fur is also lighter. Their forearm is small, their ears are relatively broad, and the tragus has a narrow and pointed tip. The glans penis has up to ten spines on the head, mainly in two rows. [3][2] They are similar in appearance to other broad-nosed bats such as the Greater, Inland, Northern and Eastern broad-nosed bats.[5] But most notably, they are almost impossible to differentiate in the field where their ranges overlap such as Northern Broad-nosed bats where their ranges overlap in the Kimberley.[3]
The range of Scotorepens greyii includes all of mainland Australia, but it is not found in the southern half of Western Australia and South Australia, Tasmania, Cape York Peninsula, most of the south eastern coast and most of Victoria.[3] Although they have a broad range, their abundance within the range is relatively small and blurred by crossover range from similar species.[5]
They live in mostly hot arid regions but also reside in more temperate tropical areas. These areas range from dry grasslands, sandy deserts, inland rivers with redgums, monsoon forests, melaleuca forests, open forests, mixed shrubland and paperbark swamps. They are commonly caught around water.[3][4][2][5]
Like most bats, the little broad-nosed bat is nocturnal and begins being active soon after sunset. They rely on good eyesight and echolocation to find their prey.[4]
The little broad-nosed bat is an insectivore which feeds and drinks while in flight. They forage for prey close to tree tops, over water, open grassland and other open habitat. They are characteristically fast fliers which make abrupt darts and turns to catch prey. They eat a lot of beetles, bugs and ants. They also consume moths, termites, cockroaches, katydids, crickets, flies and lacewings. They drink while in flight and are known to be feisty; they have been observed preying on moths their own size.[3][4][2][5][6]
Little broad-nosed bats are known to roost in hollows, usually in trees but they have also been found in fence posts and in the space under metal caps of telegraph poles. They will also roost in disused buildings; 20 individuals have been found roosting in one area.[3][4] It is thought that Scotorepens greyii has some kind of seasonal migration or seasonal change in foraging behaviour due to extreme differences in bat numbers found at different times of the year.[3]
Despite its small size, the little broad-nosed bat is able to survive the extreme summer temperatures in its arid Australian environment by utilizing torpor and roost selection to conserve energy.[7] Torpor helps the bats retain body water and reduces heat production from metabolic reactions.[7] S. greyii minimizes energy expenditure using passive rewarming from its lethargic state. Roosting in poorly insulated dead trees allows solar radiation to rouse them instead of physical activity.[7] Most endotherms perform thermoregulation, an energetically demanding process where an organism uses metabolic processes along with physiological changes to control body temperature. Little broad-nosed bats are able to alternate between thermoregulation and thermoconformation, a process where body temperature fluctuates with ambient temperature, to save energy and delay hyperthermia.[8]
Scotorepens greyii has different mating behaviour depending on where the bats are located. It is thought that in more arid areas mating begins before winter in April and they give birth in October while in more temperate areas they are known to mate during winter and give birth in late spring or summer. They frequently give birth to twins and the young bats are capable for foraging within one to two months.[3]
They are not considered endangered or threatened. Although there are no major threats to the species they are vulnerable to loss of roost sites in tree hollows and loss of feeding grounds by forestry activities, clearing for agriculture and housing.[6]

Scotorepens greyi (Gray, 1842) è un pipistrello della famiglia dei Vespertilionidi diffuso in Australia.[1][2]
Pipistrello di piccole dimensioni, con la lunghezza della testa e del corpo tra 37 e 53 mm, la lunghezza dell'avambraccio tra 27 e 35 mm, la lunghezza della coda tra 25 e 48,5 mm, la lunghezza delle orecchie tra 10 e 13 mm e un peso fino a 11 g.[3]
Le parti dorsali variano dal bruno-giallastro al bruno-rossastro, mentre le parti ventrali sono grigio chiare. Il muso è molto largo, dovuto principalmente alla presenza di due masse ghiandolari sui lati. Inoltre è presente un distinto tubercolo tra l'angolo posteriore del muso e la base dell'orecchio. Le orecchie sono relativamente larghe, bruno-giallastre, con il margine anteriore leggermente convesso, la punta arrotondata e il lobo basale anteriore piccolo. Il trago è curvato in avanti, con il bordo anteriore leggermente concavo e quello posteriore convesso. La coda è lunga ed inclusa completamente nell'ampio uropatagio.
Emette ultrasuoni a basso ciclo di lavoro sotto forma di impulsi di breve durata con una frequenza iniziale a 38,38±0,88 kHz, finale a 64,51±9,47 kHz e massima energia a 40,06±0,82 kHz[4].
Si rifugia in colonie fino a 20 esemplari nelle cavità degli alberi, edifici abbandonati ed altre strutture disponibili.
Si nutre di insetti.
Questa specie è diffusa nell'Australia occidentale nord-occidentale e settentrionale, Territorio del Nord, Queensland escluso la Penisola di Capo York, Australia meridionale nord-orientale e Nuovo Galles del Sud.
Vive nei boschi aridi e nelle pianure vicino a specchi d'acqua.
La IUCN Red List, considerato il vasto areale, la popolazione numerosa e la presenza in diverse aree protette, classifica S.greyi come specie a rischio minimo (LC).[1]
