Interpretive Summary: Many plant diseases such as “Pierce’s Disease” (PD) in grape (Vitis vinífera L.), “Phony Peach Disease” (PPD), “Coffee Leaf Scorch” (CLS), “Oleander Leaf Scorch” (OLS), and “Citrus Variegate Chlorosis” (CVC) are produce for a bacteria endemic of the Americas. The bacteria enter the plant through sap feeding insects of the subfamily of leafhoppers. This note provides information about distribution of potential disease vectors in South America. The 3 main insect collections of Argentina were examined and as result 5 species are cited for the first time from Paraguay; 4 for Perú; 3 for Bolivia; 2 for Ecuador; and 1 each for Uruguay and Brazil.

Technical Abstract: Xylella fastidiosa is endemic to the Americas, it causes economically important diseases in a variety of different crops, and is transmitted by xylem-feeding sharpshooters. This paper provides new geographic records for Proconiini sharpshooters in South America which help to better understand their distribution. To develop these new records, we examined material from 3 of the main entomological collections held in Argentina. As a result, 5 species are cited for the first time from Paraguay; 4 for Perú; 3 for Bolivia; 2 for Ecuador; and 1 each for Uruguay and Brazil. Some of the species could be vectors of X. fastidiosa because congeners of the species studied here are known to transmit this bacterium.
