Meriola fasciata Platnick & Ewing, 1995: 26 , figs 59–63. FIGURE 28.

Diagnosis. Males ( Figs 29–30 ) resemble those of M. avalosi sp. nov. by the long RTA with bent tip, but differ by the longer, sinuous embolus, by lacking the bulb distal projection, and by lacking a basal spine on the dorsal side of the femur II. Females ( Fig. 28 ) are easily recognized by the long tube-like anterior hood of the epigyne. Description. See Platnick & Ewing (1995) for male and female descriptions. Natural history and habitat. The specimens were collected in forests and grasslands; many were found in dry forests (xerophilic and semi-xerophilic forest), with pyrophilus plants, such as Baccharis sp., but also in humid forests. Distribution. Known from south of Brazil , Uruguay and center of Argentina ( Fig. 91 ). FIGURE 29.
