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 ).
