Male genitalia; Pygofer ( Figs. 36-37 ) in posterior view almost circular; dorsal margin of diaphragm with two triangular lobes; anal tube ( Figs. 38-39 ) with each latero-apical angles produced ventrad in a slender spine; parameres ( Fig. 40 ) broAD, “S” shApeD with the LAtero- apical angle strongly produced; aedeagus ( Fig. 41 ) abruptly bent near base, distal portion tubular, porrect, with a ridge thickening traversing each side almost through the whole length ( Fennah 1955, 1957).

Previously recorded for Robinson Crusoe Island, Juan Fernández ( Chile), Argentina and Uruguay ( Fennah 1955, Remes-Lenicov & Tesón 1978, Remes-Lenicov et al. 2000). This record fills the gap between Juan Fernández Islands and the oriental side of the southern cone. Description of the female in Remes-Lenicov & Tesón (1978) and Tesón & Remes-Lenicov (1983). Immature stages described by Remes-Lenicov et al. (2008). This species has being extensively studied for being the main vector of Mal de Río Cuarto maize virus in Argentina (e.g. Remes-Lenicov et al. 1985, Grilli & Gorla 1997, 2002, Truol et al. 2001).
