|Scientific Name:||Myotis alcathoe|
|Species Authority:||von Helversen & Heller, 2001|
|Taxonomic Notes:||Formerly included in Myotis mystacinus (Kuhl, 1817); the species was differentiated (von Helversen et al. 2001) on the base of karyological, genetic and echolocation characters.|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Assessor(s):||Hutson, A.M., Aulagnier, S., Nagy, Z., Karataş, A., Palmeirim, J. & Paunović, M.|
|Reviewer(s):||Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Temple, H. (Global Mammal Assessment Team)|
The species has been recently described (2001) and is known from few localities. It is not easy to identify morphologically. More localities are being reported, but insufficient information is currently available on the extent of the range, population size and population trends. Consequently it is assessed as Data Deficient. Based on present knowledge the species is endemic to Europe.
|Range Description:||This species was recently described and is poorly known (von Helversen et al. 2001), but current information suggests that it is endemic to central and southern Europe. It is known from Spain, France, Switzerland, Germany, Czech Republic, Slovakia, Hungary, Montenegro, Romania, Bulgaria, and Greece (Ruedi et al. 2002, Benda et al. 2003, Agirre-Mendi et al. 2004, von Helversen 2004, Helversen et al. 2006, P. Benda in litt. 2006). The species is possibly present for most of Serbia and areas of Montenegro (M. Paunovic pers. comm. 2007).|

|Population:||Its population size and trend is unknown. To date, c.15 localities are recorded in international publications (von Helversen 2001, Benda et al. 2003, von Helversen 2004). However, new localities continue to be found (EMA Workshop 2006, Mediterranean Mammals Workshop 2007).|
|Habitat and Ecology:||According to present scarce knowledge, it is a tree dwelling and forest foraging species. In parts of the range at least it prefers to hunt in small valleys with deciduous trees and flowing water, which is a threatened habitat. The only breeding colony was found in a tree hollow. It may also occur in rural gardens and urban habitats. It probably occurs in underground habitats in winter.|
|Major Threat(s):||Damage to riparian forest is believed be a threat in parts of range (von Helversen et al. 2001). Wider forest and roost tree loss (especially in wet old growth forests) may also be threats.|
|Conservation Actions:||It is protected by national legislation in most range states. There are also international legal obligations for the species' protection through the Bonn Convention (Eurobats) and Bern Convention. It is included in Annex IV of the EU Habitats and Species Directive, and some habitat protection may be provided through Natura 2000. Conservation recommendations include further research on distribution, population status and trends, ecology, habitat requirements, and threats. Measures to increase public awareness of this little-known species are also recommended.|
