"Ants are continually introduced into regions outside of their natural biogeographic ranges via global trade. The genus Strumigenys Smith 1860 (Formicidae: Myrmicinae) are minute predators with a growing history of global introductions, although tropical introductions into temperate zones are rarely able to establish outside of heated infrastructures. We report the first record of the Australasian Strumigenys perplexa (Smith 1876) to Europe and the British Isles from four sites on Guernsey, Channel Islands. This novel discovery is likely attributable to the species wide climatic and habitat tolerances, enabling the species to establish away from its natural range in Australasia and from heated-infrastructure. A key to the West Palaearctic Strumigenys species is provided alongside a preliminary and critical checklist of ant species recorded from the Channel Island archipelago, listing 32 species." . . .
