Description

Meriola fasciata Mello-Leitão

Figs 1 a–b, 2e–g, 4a–b, 28–30, 91

Trachelopachys fasciatus Mello-Leit „o, 1941a: 178, fig. 70, pl. X, fig. 48 (four female syntypes from Cabana, Cordoba, Argentina, in MLP, examined by Platnick & Ewing, 1995).

Trachelas fasciatus Platnick, 1975: 10.

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

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).
