The orsillid genus Nysius Dallas is a complex and large genus with more than 100 described species worldwide, and includes many species of agricultural importance, one such example is N. simulans (Stal) from Argentina. Three species of Nysius are found in this country: N. simulans (Stal), N. irroratus (Spinola) and N. puberulus Berg. The material available for the present study, consisting of over 610 specimens, was collected by sweep-net, G-Vac and light trap in the provinces of Chubut (42 degrees to 46 degrees S; 63.5 degrees to 72 degrees W), La Pampa (35 degrees to 39 degrees south; 63 degrees to 68 degrees West), Neuquen (36 degrees to 41 degrees S; 68 degrees to 71 degrees W) and Rio Negro (37 degrees to 42 degrees S; 62 degrees to 71 degrees W), in the central region of Argentina, during the years 2010-2014. Although the species N. simulans is frequently recorded as a pest of soybean crop, there exist no detailed description but only a brief general diagnosis. In the present contribution, therefore, we provide a detailed redescription as well as an updated distribution of N. simulans and N. irroratus, and a key for species of genus Nysius present in Argentina.
