There is a need to confirm that these new records are of P. eisentrauti and not of a related species.	20000000	Hypsugo eisentrauti	Data Deficient		2019	2018-08-26 00:00:00 UTC	3.1	English	Listed as Data Deficient in view of continuing problems with its taxonomy as well as absence of recent information on its extent of occurrence, status, ecological requirements and threats. This species is most probably restricted to SW Cameroon. However, there are supposedly records from four other countries. Those records may all be misidentifications. If that is the case, then it is likely that this species has a very restricted range and is probably threatened.	This is typically a forest species, and has been recorded from montane and presumably lowland tropical moist forest, and possibly from tropical dry forest and mangrove forest.	The threats to this species are not well known, but in Cameroon are likely to include encroachment on montane forest by subsistence agriculture.	The population is little known, but it may be locally common in Cameroon.	Unknown	This species was initially described from Cameroon, where it has been recorded from localities including the Rumpi Highlands, Mount Kupe and Mount Cameroon. Although there are additional records of this species from Kenya, Somalia, Uganda and from the Democratic Republic of the Congo, it is uncertain that these actually refer to Pipistrellus eisentrauti . Confirmation of the possible distribution outside of Cameroon is needed.		Terrestrial	It is unclear if the species is present within any protected areas. Further studies are needed into the taxonomy, distribution, and threats to this species.	Afrotropical		FALSE	FALSE	Global	Simmons, N. B., & Cirranello, A. L. (2023).
