|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. & Paunović, M.|
|Contributor(s):||Aulagnier, S., Nagy, Z., Karataş, A. & Palmeirim, J.|
European regional and Global assessment: Data Deficient (DD)
EU 28 regional assessment: Data Deficient (DD)
The species was only recently described (2001) and is known from few localities. It is not easy to identify morphologically. More localities are being reported, but no information is available on size of range and population or population trend. Consequently it is assessed as Data Deficient. Based on present knowledge the species is endemic to Europe and 90% of known locations are inside the EU.
|Previously published Red List assessments:|
The Alcathoe Myotis (Myotis alcathoe) 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 occurs in Spain, France, Switzerland, Germany, Czech Republic, Slovakia, Hungary, Montenegro, Serbia, Bulgaria, and Greece (Ruedi et al. 2002, Benda et al. 2003, Agirre-Mendi et al. 2004, von Helversen 2004, von Helversen et al. 2006, P. Benda in litt. 2006). Recent records revealed this bat’s presence also in Austria, Poland, Belgium, Romania and the United Kingdom (Spitzenberger et al. 2008, Jan et al. 2010, Sachanowicz et al. 2012, Uhrin et al. 2014, Nyssen et al. 2015).

This species’ population size and trend are unknown. To date, ca. 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).
|Current Population Trend:||Unknown|
|Habitat and Ecology:|
According to present scarce knowledge, the Alcathoe Myotis is a tree dwelling and forest foraging species, feeding primarily on moths and nematoceran flies (Lučan et al. 2009, Danko et al. 2010). It seems to prefer old and full-grown oak forests (Lučan et al. 2009, Danko et al. 2010), but may also occur in rural gardens and urban habitats. It probably exploits underground habitats in winter. Summer colonies may number up to 80 individuals. The only known breeding colony was found in a tree hollow.
|Generation Length (years):||5.8|
|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 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 & 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.|
