This species can be distinguished from all other species of the genus by the following characters: apical half of telomere narrowing to a sharp apex in males; in females, the posterior margin of sternum VII with a narrow sinus and spermatheca with bulga as long as hilla ( Smit 1987). These are the first records of the species for La Rioja Province. The localities correspond to the Monte Desert of Mountains and Isolated Valleys eco-region.
