Alloscirtetica weyrauchi Michener, LaBerge & Moure View in CoL

( Figs. 7–11 View FIGURES 7 – 10 View FIGURE 11 )

This species is distributed from central-southern Peru to central Bolivia, mainly in mountainous areas about 2600 meters above sea level. The description of this species was based on males collected in Tarata ( Peru), the same that were studied by Urban, along with other male specimens, in her revision of the species of Alloscirtetica published in 1971. In that paper, she reported males of this species in Bolivia, although the females had never been observed. During travels in northern Chile in 2000, Laurence Packer (York University, Canada) collected males and females of A. weyrauchi in Zapahuira (Region of Arica and Parinacota). These are the first records of this species from Chile ( Fig. 11 View FIGURE 11 ). As the female of this species remained unknown until now, a description is given here to permit its identification.
