Interpretive Summary: The Proconiini sharpshooters are large leafhoppers that are known for their capacity to transmit diseases to plants, like Pierce ‘s disease and Oleander leaf scorch. They are xylem sap feeders; the xylem transports water and soluble mineral nutrients from the roots throughout the plant. Given that Proconiini sharpshooters are vectors of plant diseases, the knowledge of insect species present in a country is basic information to enable identification of potential sharpshooter species, vectors of plant diseases. In this article, we summarized the available information of Proconiini sharpshooters of Argentina, where 14 species of sharpshooters are mentioned for the first time occurring in this country. In addition information on geographic distribution, host plants and parasitoids is provided for several species.

Technical Abstract: The American tribe Proconiini is one of the largest groups of xylem-feeding insects and includes the majority of the known vectors of xylem-born phytopathogenic organisms. The significance of the diseases transmitted by them gives the group an important role as pests, mostly for citrus fruit, grapes and almonds. So far, the knowledge of these Hemiptera in Argentina was scarce and the information was fragmentary so, the aim of this contribution is to summarize the available information of the Proconiini sharpshooters in Argentina. In addition, 14 species are mentioned for the first time occurring in the country, and new distributional data are given for 18 species; 34 new associations of host plants-sharpshooters are recorded. New records of egg parasitoids are given for Dechacona missionum, Molomea consolida, M. lineiceps and Tapajosa similis.
