and described as a new species in 2014 after a team from the Institut de Biologia Evolutiva in Barcelona collected the holotype in 2008. ''L. balearicus'' is confined to the island of Majorca and it is the first known endemic ant species from the Balearic Islands and the first known endemic ''Lasius'' species from any Mediterranean island.
