Meriola penai Platnick & Ewing Figs 3 a–c, 4e–f, 4h, 58–60, 94a Meriola penai Platnick & Ewing, 1995: 20, figs 44–48 (male holotype and female allotype from Tolhuaca, Malleco, Región de la Araucania (IX), Chile, in AMNH, not examined). Diagnosis. Both sexes resemble those of M. tablas by the similar body shape and the relatively flat oval carapace and uniform abdominal pattern, but have depressed setal bases associated to large tubercles on the carapace surface (3A–C). Males (Figs 59–60) can be easily recognized by the long RTA that is not widened at the base. Females (Fig. 58) differ by the wide anterior hood (Figs 58h, i) and the poorly defined CDR chamber (Platnick & Ewing 1995: fig. 48). Description. Male and female described by Platnick & Ewing (1995). Natural history and habitat. The specimens were found between 300–1200 m altitude, by beating shrubs of Fuchsia magellanica, Berberis sp. and Cupressaceae, with Berlese of leaf litter at the base of Lomatia hirsuta, and by fogging in forests of Nothofagus and Araucaria. Several female and male specimens were collected by pitfall traps. Distribution. Known from Neuquén, Río Negro and Chubut provinces in Argentina and from regions VII to XI in Chile (Fig. 94a).
