The mammals represent the second largest vertebrate class in Armenia, after birds, with 83 species recorded in the country (Table 2.15). Over the last 10 years research has identified the presence of seven bat species which had not previously been recorded. These included the grey long-eared bat (Plecotus austriacus), barbastelle (Barbastella barbastella), Leisler's bat (Nyctalus leisleri), Nathusius's pipistrelle (Pipistrellus nathusii), Savi's pipistrelle (Pipistrellus savii), particoloured bat (Vespertilio murinus) and the European free-tailed bat (Tadarida teniotis).
