Diagnosis. Males ( Figs 8–9 View FIGURE 8 View FIGURE 9 ) are recognized by the small, hook-shaped, subdistal RTA ( Figs 9 View FIGURE 9 b–d; Platnick & Ewing 1995: figs 65, 66). Females ( Fig. 7 View FIGURE 7 ) resemble those of M. peras sp. nov. by the epigyne lacking a hood and with a wide median field, but differ by the narrower, bean-shaped secondary spermathecae and by the shorter, not arcshaped, lateral epigynal ridges ( Platnick & Ewing 1995: figs 67, 68).

Description. See Platnick & Ewing (1995).

Natural history and habitat. Specimens were collected in grass, succulents or under rocks. The specimens from U.S.A. and Chile belong to the Matorral region, where the most typical communities include sclerophyllous forest, xeric scrub and Mediterranean forest. Those from Robinson Crusoe Island were found under stones in a disturbed, dry area with little vegetation. The rest were collected in the Chacoan subregion, where vegetation is predominantly xerophyllous forest and graminaceous steppes or in temperate rainforest. Some male specimens were collected with pitfalls.

Distribution. Known from Cochabamba in Bolivia, south of Brazil and Uruguay, Argentina and center and south of Chile. Probably introduced in California, U.S.A., and Easter Island (Baert et al. 1997). Some records from temperate forests in southern Argentina and Chile and in Robinson Crusoe Island, Juan Fernández Archipelago, may represent anthropic introductions as well.
