''Falsistrellus'' is a genus of

vespertilionid Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat familie ...

family of bats, small predatory flying mammals. They are known from Australia. The poorly researched species have been variously placed by authors, and revised again by studies of their distinct characteristics, consequently the falsistrelles may also be referred to as pipistrelles or false pipstrelles.

Taxonomy

Common names for the species include falsistrelle and false pipistrelle. The description of the genus was published in 1943 by

Ellis Le Geyt Troughton Ellis Le Geyt Troughton (born in Sydney on 29 April 1893; died 30 November 1974) was an Australian zoologist and mammalogist. Biography Ellis Troughton began to exercise his interest in mammals at fourteen years of age, taking a role at the A ...

Pipistrellus ''Pipistrellus'' is a genus of bats in the family Vespertilionidae and subfamily Vespertilioninae. The name of the genus is derived from the Italian word , meaning "bat" (from Latin "bird of evening, bat"). The size of the genus has been co ...

The species outside of Australia have been supposed to be conspecific, and those endemic to the continent separated by a variety of taxonomic treatments. The limited morphological or morphometric analyses lent support to some arrangements, yet remained inconclusive in their implications to ranks of genus and species of associated taxa. The phylogenetic study of '' Falsistrellus petersi'' and '' Nyctalus plancyi'' in 2012, then later work on vespertilionid taxa of the region, had implications for the inclusion of

Species

As workers began to outline the diversity of vespertilionids during twentieth century several taxa were allied as the ''affinis'' group (Tate, 1942. ''et al''), currently named as ''Falsistrellus affinis'', ''F. petersi'' and the inclusion or omission of species ''F. mordax''. The Australian taxa were named for the type as a ''tasmaniensis'' group, which came to include the western population as ''F. mackenziei''. The ASM MammalDiversity Database recognizes two species: *genus ''Falsistrellus'' * Eastern false pipistrelle or eastern falsistrelle, ''Falsistrellus tasmaniensis'' An Australian endemic, named for
