Description

Meriola virgata Simon

Figs 86–88, 95a

Trachelas virgatus Simon, 1904: 105, fig. 4 (one male and three female syntypes from La Herradura, Elqui, Región de Coquimbo, Chile, in MNHN, examined by Platnick & Ewing 1995).

Meriola virgata Platnick & Ewing, 1995: 12, figs 3, 19–23.

Diagnosis. Males (Figs 87–88) resemble those of M. nague by the sinuous embolus with a retrolateral origin, but differ by the longer and dorsally curved RTA, and by the longer and ribbon-like embolus. Females (Fig. 86) resemble those of M. nague by their median excavation, but it is wide and triangular in M. virgata, and by their S2, elongated and diverging (Platnick & Ewing 1995: figs 22, 23).

Description. Male and female described by Platnick & Ewing (1995).

Natural history and habitat. The specimens were collected in forests and bushes by hand collecting. The specimen collected by fogging, at 1100 m of altitude, was found in a forest of Nothofagus dombeyi.

Distribution. Known from Región IV to VIII in Chile (Fig. 95a).
