Meriola puyehue Platnick & Ewing

Figs 64–66 , 95a

Meriola puyehue Platnick & Ewing, 1995: 31 , figs 77–81 (female holotype from Parque Nacional Puyehue , Osorno, Región de los Lagos (X), Chile, in AMNH, examined from photographs, thanks to Ricardo Botero Trujillo; Fig. 66 e–f).

Diagnosis. Males ( Figs 65 , 66 a–d) are recognized by the very short embolus, concealed by the distal tegular lobe, and by the short, digitiform RTA that is directed dorsally. Females ( Figs 64 , 66 e–f) are recognized by the elevated transversal ridge in the middle of the epigine, the paired hoods below that, and the twisted copulatory ducts ( Platnick & Ewing 1995: fig. 81).

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

Natural history and habitat. The new records were collected by fogging in Nothofagus forests at an altitude of 1200 m.

Distribution. Known from Malleco and Osorno provinces in Chile and adjacent Río Negro province in Argentina ( Fig. 95a ).
