The first Psyllid for Iceland: Trioza anthrisci Burckhardt, 1986, and an update of the Icelandic Auchenorrhyncha fauna: (Insecta: Hemiptera)

Abstract

The Icelandic fauna of Auchenorrhyncha and Psylloidea was assessed at 14 locations in the south, west and north of the country in August 2013. In total, 1,556 individuals belonging to six species were recorded: Javesella pellucida, Ribautiana ulmi, Edwardsiana rosae, Cicadula quadrinotata, Macrosteles laevis and Jassargus pseudocellaris. Edwardsiana rosae and R. ulmi have only been found in Reykjavík, while the other species are all widespread and common on Iceland. Two further species known to occur on Iceland were not recorded: Evacanthus interruptus and Philaenus spumarius, which both have very restricted distributions. Additionally, with the finding of Trioza anthrisci Burckhardt (Hemiptera: Triozidae) the first psyllid species was recorded from Iceland. One female was found near the airport of the northern town of Akureyri. Some of this species’ main host plants (Angelica sylvestris and the introduced Anthriscus sylvestris) are widespread in the coastal lowlands, but might not have been adequately sampled during earlier investigations. Because only one individual was found, and because of its proximity to an airport, the native status of the species for Iceland remains to be determined, but is not unlikely given its northern occurrence in Scandinavia.
