Scotorepens sanborni (Troughton 1937)

Scotorepens sanborni és una espècie de ratpenat de la família dels vespertiliònids. Viu a Austràlia (Territori del Nord, Queensland i Austràlia Occidental), Indonèsia (Irian Jaya) i Papua Nova Guinea. El seu hàbitat natural són terres baixes del bosc tropical humit, bosc escleròfil, boscos costaners, i sabana. No hi ha cap amenaça significativa per a la supervivència d'aquesta espècie.^[1]

Aquest tàxon fou anomenat en honor del zoòleg estatunidenc Colin Campbell Sanborn.^[2]

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.

Taxonomy

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]

Description

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]

Distribution and habitat

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]

Behaviour

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]

Scotorepens sanborni (Troughton, 1937) è un pipistrello della famiglia dei Vespertilionidi diffuso in Australia, Nuova Guinea e Timor.^[1][2]

Descrizione

Dimensioni

Pipistrello di piccole dimensioni, con la lunghezza della testa e del corpo tra 37 e 52 mm, la lunghezza dell'avambraccio tra 28 e 36 mm, la lunghezza della coda tra 27 e 39 mm, la lunghezza del piede tra 7,1 e 9 mm, la lunghezza delle orecchie tra 9 e 13 mm e un peso fino a 9,1 g.^[3]

Aspetto

Le parti dorsali variano dal bruno-rossastro al marrone, mentre le parti ventrali sono bruno-grigiastre chiare con la punta dei peli bianca. Il muso è molto largo, dovuto principalmente alla presenza di due masse ghiandolari sui lati. Le orecchie sono strette, arrotondate e con un lobo basale anteriore semicircolare. Il trago è curvato in avanti, con il bordo anteriore leggermente concavo e quello posteriore convesso. Le membrane alari sono bruno-nerastre. La coda è lunga ed inclusa completamente nell'ampio uropatagio.

Biologia

Comportamento

Si rifugia in colonie fino a diverse centinaia di esemplari nelle cavità degli alberi e negli edifici. Caccia solitamente lungo i fiumi, nelle baie, lungo sentieri e strade e intorno alle luci delle città.

Alimentazione

Si nutre di insetti, in particolare zanzare e moscerini, che cattura in volo a non più di 5 metri dal suolo o dagli specchi d'acqua.

Riproduzione

Sono state osservate femmine gravide in Australia tra i mesi di agosto e settembre, mentre in Nuova Guinea a dicembre. Danno alla luce 1-2 piccoli una volta l'anno.

Distribuzione e habitat

Questa specie è diffusa lungo le coste settentrionali dell'Australia occidentale e del Territorio del Nord, Queensland settentrionale, Nuova Guinea sud-orientale, isola di Yos Sudarso e Timor.

Vive nelle foreste umide tropicali, foreste di sclerofille e savane fino a 2.200 metri di altitudine. Nella regione di Kimberley è stato osservato soltanto nelle mangrovie.

Stato di conservazione

La IUCN Red List, considerato il vasto areale, la popolazione numerosa e la presenza in diverse aree protette, classifica S.sanborni come specie a rischio minimo (LC).^[1]

Scotorepens sanborni is een vleermuis uit het geslacht Scotorepens die voorkomt in Noord-Australië (in twee populaties: Kimberley-Top End en Noordoost-Queensland), op Timor en op Zuid-Nieuw-Guinea en Dolak. Door sommigen wordt deze soort tot S. balstoni gerekend. Deze soort lijkt sterk op S. balstoni en S. greyii, maar is daar genetisch van te onderscheiden. Het dier slaapt in holle bomen of gebouwen en eet kleine insecten en mijten. In september, oktober en november worden jongen geboren.

Scotorepens sanborni^[2][3][4] är en fladdermusart som först beskrevs av Ellis Le Geyt Troughton 1937. Scotorepens sanborni ingår i släktet Scotorepens och familjen läderlappar.^[5][6] Inga underarter finns listade i Catalogue of Life.^[5]

Denna fladdermus förekommer i norra Australien (främst på Kap Yorkhalvön), i södra Nya Guinea och på Timor. Arten vistas främst i låglandet men når i bergstrakter 2200 meter över havet. Habitatet utgörs av olika slags skogar och savanner. Individerna vilar i trädens håligheter, i byggnader eller i andra gömställen. Där bildar de kolonier med upp till några hundra medlemmar. Per kull föds en eller två ungar.^[1]
