Plagiolepis alluaudi emery, 1894, a globally spreading exotic ant (Hymenoptera, Formicidae) newly recorded from Tenerife (Canary Islands, Spain).
Exotic ants have been a prevalent ecological problem, particularly in tropical and subtropical islands. Here Plagiolepis alluaudi Emery, 1894 is recorded from the island of Tenerife (Canary Islands, Spain) for the first time, where it was commonly encountered in the town Puerto de la Cruz. This is the first Canary Islands record of this species that is presumably native to Madagascar and surrounding islands. Whether or not P. alluaudi will be able to spread into natural Canary ecosystems that have a high share of endemic species is unknown.
