Figs 43–45, 96
Trachelas longitarsis Simon, 1904: 104, fig. 5 (male holotype from Punta Arenas, Magallanes, Región de Magallanes, Chile, in MNHN 12913, labeled as “Chili”, examined; Fig. 45b, c, g–i).
Meriola longitarsis Platnick & Ewing, 1995: 18, figs 34–38.
Diagnosis. Males (Figs 44 a–f, 45) are easily distinguished by a combination of an elongated cymbium constricted at the middle, a long, filiform embolus, and the distally pointed tegulum. Females (Fig. 43, 44g) are recognized by the rectangular median field located posterior to the copulatory ducts and spermathecae, and the large, rounded secondary spermathecae (Platnick & Ewing 1995: figs 37, 38).
Description. See Platnick & Ewing (1995) for male and female descriptions.
Variability. The males show continuous variability in palpal morphology, with a long embolus and curved cymbium (Fig. 45 h–i) to a shorter embolus and straighter cymbium (Fig. 45 e–f and Platnick & Ewing 1995: figs 34–36).
Natural history and habitat. The specimens were collected by fogging in forests of Laurelia sp., Myrceugenia sp., Nothofagus dombeyi, N. oblicua, N. alpina, Castanopsis hystrix, Podocarpus saligna, Austrocedrus chilensis and Araucaria araucana, between 900–1200 m altitude. A few specimens were found in low coastal forest, hygrophilic forests and forests of Peumus boldus.
Distribution. Known from a Chile, in Choapa, Quillota, Curicó, Concepción, Malleco and Valdivia provinces in Chile, and adjacent localities in Neuquén, Río Negro and Chubut provinces in Argentina; the holotype however is from Punta Arenas, far to the south (Fig. 96).
