The Canary archipelago is situated in the Atlantic Ocean off the African coast. The archipelago ismade up of eight oceanic and volcanic islands and islets. Seven species of bats are known toinhabit the archipelago: six of which belong to family Vespertilionidae(Plecotus teneriffae, Hypsugosavii, Pipistrellus maderensis, Pipistrellus kuhlii, Barbastella barbastellus and Nyctalus leisleri) andone to family Molossidae (Tadarida teniotis). The presence of these species among the islands ofthe archipelago is variable, so the western islands (Tenerife, La Gomera, La Palma and El Hierro)have the greatest diversity of species, Tenerife being the island with the largest number of species(six of the seven). In comparison, the eastern islands show lower species richness, with threespecies in Gran Canaria and a single species in Lanzarote and Fuerteventura. In this study, wedescribe morphologically the teeth of 31 individuals from the different extant species of bats fromthe archipelago. The results obtained allow us to differentiate them when any isolated dental remains are found associated with a paleontological or archaeological site. This will increase what is known of the paleodistribution and the paleobiological data of this group in the Canary Islands.
