Trachelas foraminosus Keyserling, 1891: 60   , fig. 32 (female holotype from Rio Grande , Rio Grande do Sul, Brazil, in BMNH, examined by Platnick & Ewing, 1995).

Meriola foraminosa Platnick & Ewing, 1995: 29   , fig. 72–76.

Diagnosis. Both sexes present depressed setal bases associated with tubercles covering the carapace surface. Males ( Figs 32–33 View FIGURE 32 View FIGURE 33 ) can by distinguished by the short, twisted embolus, RTA nearly triangular with acute tip, and the presence of a distal spine on the prolateral side of femora II and III. Females ( Fig. 31 View FIGURE 31 ) can be also distinguished by the narrow anterior epigynal hood and the well separated copulatory openings and the very wide median field.

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

Natural history and habitat. Several specimens were collected in pitfall traps in forests and shrub steppes, between rocks.

Distribution. Known from a few localities in Venezuela, Ecuador, Perú, Brazil, Chile, and from La Rioja, Buenos Aires, Neuquén and Río Negro provinces in Argentina ( Fig. 89 View FIGURE 89 ).
