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

Chile
(
Fig. 94a
