Koopman in 1993, and at the time the two were placed in Pipistrellus , but in subgenus Falsistrellus . In 2018, the phylogenetic reconstructions of T. Gorfol and G. Csorba revealed this species to be sister to F tasmaniensis within an “Australian clade” of Vespertilioninae (including Vespadelus , and Chalinolobus ), distantly related to Hypsugo petersi , which clustered with some Hypsugo species from South Asia. Monotypic.	SW Australia , from near Perth to the W margin of the Wheatbelt.	Head-body 55-67 mm, tail 40-53 mm, ear 14-18-3 mm, hindfoot 8:2-11-6 mm, forearm 48-54 mm; weight 17-26 g. The Western False Pipistrelle is slightly larger than the Eastern False Pipistrelle ( F tasmaniensis ) and has a rustier hue to the pelage. Dorsally, it is rusty brown; underparts are light cinnamon-brown. Baculum is short with a broad base, proximally widened, roof-like in cross section, and without distal expansion; unlike the Eastern False Pipistrelle, the dorsal basal transverse ridge is notched at the center; ridge projects behind ventral posterior edge of base. Skull large and robust; superorbital tubercles small to moderate; infraorbital foramen small to moderate, separated from orbit by moderate lacrimal bar; bulla length moderate. Dental formula for hoth species of Falsistrellus is 12/3, C 1/1, P 2/2, M 3/8 (x2) = 34. Dentary similar to that of Eastern False Pipistrelle, but longer relative to basicranial length. P* has buccal edge moderately notched. Condylo-canine length 17-9-18-3 mm; maxillary tooth row 7-3-7-8 mm.	Restricted to tall forest. The Western False Pipistrelle is typically found in wet sclerophyll forest, dominated by karri ( Eucalyptus diversicolor, Myrtaceae ); in high rainfall zones, it occursin jarrah (E. marginata) and tuart (E. gomphocephala) dry sclerophyll forests. Also recorded in mixed tuartjarrah tall woodlands on adjacent coastal plains. It has also been captured in Banksia ( Proteaceae ) woodlands on the Swan Coastal Plain.	Western False Pipistrelles forage on insects above the understory, in the tree canopy, and along forest tracks. Their high agility enables them to outmaneuver and catch airborne insect prey among massive tree trunks.	A single young is born in spring or early summer.	In 1992, over three nights 24 Western False Pipistrelles were captured while foraging 4-8 m aboveground, where their flight was fast and direct, with occasional abrupt turns. During daytime, the species roosts in hollows in old trees, branches and stumps. Echolocation calls end at low frequencies (30 kHz), with most energy at 32-34 kHz, and last c.12 milliseconds.	The Western False Pipistrelle roosts gregariously. A colony of ¢.30 individuals was found in a karri hollow 15 m aboveground. Available data suggest that sexes segregate while roosting and foraging, at least during spring and early summer.	Classified as Near Threatened on The IUCN Red Lust. Western False Pipistrelles are only known from ¢.30 sites. Area of occurrence is less than 20,000 km ? within which it occurs at relatively low densities compared to other sympatric forest-dwelling bats. It is confined to the south-western corner of Australia , and has not been seen in the northern part of its range since 1993, despite searches. Population size is reckoned to be over 10,000 mature individuals, but no census has ever been undertaken. Its habitats are subject to continued logging, burning, clearing and modification for a variety of land uses including forestry, mining, viticulture, housing development. Other threats include competition for roosting resources with feral honeybees and coconut lorikeets ( Trichoglossus haematodus) in some areas.	Adams et al.

Population reduction was calculated as approaching but not exceeding 30% in three generations (21 years), its extent of occurrence (EOO) was considered &gt;20,000 km², area of occupancy (AOO) &gt;2,000 km², plus the species is not severely fragmented and it does not suffer extreme fluctuations. The species is confined to the south-western corner of Australia, and it has not been seen despite searches in the northern part of its range (north of Collie in the Jarrah forest; north of Mandurah on the Swan Coastal Plain) since 1993. Thus, the calculated reduction in EOO was 37% over 39 years, with the species now estimated to occur in only 33,750 km² of its original 53,750 km² EOO. In addition, projected reduction in EOO and AOO for the next 50 years from climate change was also anticipated to be greater than 30%. Total recent past and anticipated loss of range and habitat is therefore greater than 50% over a total of around 80 years, but the rate of decline in any given past or future ten year period is insufficient to justify a listing for this species as Vulnerable A4c. Population size was assumed to be greater than 10,000 mature individuals (Woinarski et al . 2014), but no census has ever been undertaken. It occurs at relatively low density compared to other sympatric forest dwelling bats (Webala et al . 2011), which is relevant for a species that has an EOO approaching the limits for listing in a threatened category (if the northern part of the range as illustrated by Woinarski et al . 2014 is no longer occupied). Thus, if population size estimates are revised below 10,000, it might qualify for listing under Vulnerable C2a(ii), given that the population may not be substructured.	<p>Core habitat of this species is in high rainfall forests dominated by Jarrah, Karri, Marri, and Tuart. Colonies of up to 30 animals have been found in hollow logs. It is a specialist of tall, mature forest (Start and McKenzie 2008), however it has also been captured in the past in Banksia woodland on the Swan Coastal Plain (Hosken and O’Shea 1995). Very little ecological study has been conducted on this species, but they forage under the tree canopy above the shrub layer, and along forest tracks (Webala et al . 2011). There are no data on reproduction and generation length is assumed to be around seven years (Woinarski et al . 2014).</p>	<p>The forest and woodland habitats occupied by this species are subject to continued logging, burning, clearing and modification from a variety of land uses including forestry, mining, viticulture, housing development and other activities on privately owned land. Its response to loss of habitat through burning and the removal of tree hollows in older trees and dead stags has not been studied but such losses may have implications for area of occupancy. Adding to pressure on roosting resources is competition from feral honey bees and Rainbow Lorikeets Trichoglossus haematodus in parts of their range (Woinarski et al . 2014).</p>	<p>No census of the population has been undertaken, but Woinarski et al . (2014) considered that there was enough habitat remaining in its area of occupancy to support more than 10,000 individuals. This is despite a calculated reduction in extent of occurrence of 37% in 39 years, which has occurred predominantly in the northern part of its range—north of Collie in the Jarrah forest and north of Mandurah on the Swan Coastal Plain (Woinarski et al . 2014). It can be common locally, but occurs at lower density than sympatric species such as Vespadelus regulus based on both acoustic recordings and capture effort (Webala et al . 2011).</p>	Decreasing	This species is endemic to south-western Western Australia, Australia.		Terrestrial	<p>Substantial areas of suitable habitat for this species are protected. There is a need for further surveys, a population estimate and ecological studies. Important roosting sites should be identified and protected, distribution limits defined, and studies conducted on the contrasting effects of logging and protection in national parks. Monitoring of relative abundance could be assessed through a programme based on acoustic recordings, and would be especially informative at the periphery of their range (Woinarski et al . 2014). A reassessment of this species should be a priority once better information on population size and occurrence in the northern part of its range is available. </p>	Australasian		FALSE	FALSE	Global	Simmons, N.
