Natural history. The Argentine specimens here listed were collected in areas belonging to the Chaco Biogeographic Province (records from Corrientes) and to the northern, ecotonal areas of the Pampean Biogeographic province (sensu Morrone, 2014) bordering with the former. They were found in habitats ranging from savannas and grasslands with different palm species to cultivated, disturbed areas. Most of the specimens were obtained with pitfall traps, but the female from San Justo, Santa Fe ( Fig. 5 ) was found by manual searching the bases of grasses in an area with a mixture of natural and adventitious vegetation along the roadside. The female from Parque Nacional El Palmar shows the distal part of amale embolusinserted intotheepigynum.
