Recorded Distribution(s):
This species is known only from Argentina and Chile. It was reported from the Rio Negro region in Argentina by Beamer in 1943 (49) and Bennett and Munck (1946). Oman (1949) recorded it from Chile and Linnavouri (1959) cited numerous localities in Argentina and Santiago, Chile.(Nielson, 1968)

This species is a vector of the yellow wilt virus of sugarbeet in Argentina. Bennett and Munck in 1946 (64) Were first to report transmission of this virus in 1946. Although only a limited number of tests were made, there was reasonable evidence that this species transmitted the virus. Information on virus-vector relationships was not reported.
(Nielson 1968)

Although this species is the only reported vector of yellow wilt virus of sugarbeet, further studies are necessary to confirm previous work and to determine the importance of the species through biological studies of the vector and virus
