Figs 2 a–d, 49–51, 95b

Meriola manuel Platnick & Ewing, 1995: 24 , figs 54–58 (male holotype and female allotype from San Manuel , Melipilla, Región Metropolitana, Chile, in AMNH, not examined).

Diagnosis. Males are very similar to M. tablas by the similar body shape, with a relatively flat oval carapace, and by the long, straight RTA that is widened basally, but differ by the mottled pattern of the abdomen and the longer RTA. Females ( Fig. 49 ) are also similar to M. tablas by the flat oval carapace, but differ by the mottled abdominal pattern and the smaller spermathecae.

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

Natural history and habitat. The specimens were found at altitudes between 200–800 m, in forest.

Distribution. Known from regions IV to VIII in Chile ( Fig. 95b ).
