Dos nuevos gorgojos introducidos en las islas Canarias (Coleoptera, Curculionidae)

Two probably introduced weevil species, Aulacobaris caerulescens (Scopoli, 1763) and Rhinocyllus conicus (Frolich, 1792), are recorded for the island of Tenerife. The latter thistle-headweevil may represent a potential threat for Canarian plant endemic species of Cardueae and it is suggested as a candidate for inclusion in the Spanish Catalogue of Exotic Invasive Species.
