Diagnosis. Males ( Figs 20–21 ) can be easily recognized by the long embolus that coils around the palp, and the copulatory bulb that is half the size of the cymbium. Females ( Fig. 19 ) are easily recognizable by the twisted copulatory ducts and the rounded secondary spermathecae ( Platnick & Ewing 1995: fig. 33).

Description. See Platnick & Ewing (1995) for male and female descriptions.

Natural history and habitat. The species is widely distributed over several ecoregions, from open forests with low trees, shrubs and other herbs (especially rich in grasses and legumes) to savannas and gallery forests, xeric deciduous forests with a layer of gramineous, cacti and land bromeliads, and also in urban habitats. Several specimens were collected on forests with tall trees, vines and epiphytes, woody bamboos and tree ferns. A few specimens were collected between 3000–5000 m altitude, where arborescent cacti, shrubs and grasses abound. Other specimens were collected on shrub steppes and grasslands.

Distribution. Known from central and southern Perú, Bolivia, southern Brazil, Uruguay and Argentina; in Chile known only from the far north.
