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 View FIGURE 45 , g–i).

Meriola longitarsis Platnick & Ewing, 1995: 18 , figs 34–38.

Diagnosis. Males ( Figs 44 View FIGURE 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 View FIGURE 43 , 44g View FIGURE 44 ) 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 View FIGURE 45 h–i) to a shorter embolus and straighter cymbium ( Fig. 45 View FIGURE 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 View FIGURE 96 ).
