Studied material. ARGENTINA: Chubut province, Estancia “San Román” (30 km East from Esquel on road number 40), 42° 59' S 71° 06' W, 730 m; on Adesmia sp.; December 6, 2009: 6 apterous viviparous females GoogleMaps . ARGENTINA: Neuquén province, La Bomba (km 2302 on road number 40), 39° 36' S 70° 22' W, 770 m; on Adesmia sp.; December 13, 2009: 1 apterous viviparous female. Collection of the University of León (León, Spain) GoogleMaps .

Apterous viviparous females of both samples do not show differences in qualitative features, including colour when alive and pigmentation when mounted on slides, in comparison to the type specimens of the species (Río Mayo [approximately 45° 41’ S 70° 16’ W, 510 m] ( Argentina, Chubut), on Adesmia sp., December 13, 2004). However there are some differences in the maximum and minimum limits of many of the measured characters ( Table 2). These differences can be explained because the measurements and quantities in the original description were based exclusively on the type specimens, which were most likely closely related to each other, because they had been collected on the same day and location and on plants that grew very close to each other. In contrast, the measurements determined here were taken from specimens collected in two localities distant from the type locality (Estancia “San Román” at 280 km and La Bomba at 640 km from the type locality of Río Mayo). It is possible that the intra-specific diversity is even greater because all the studied specimens are from the same month and it is possible that the apterous viviparous females might show inter-generational variability.
