Aysenia Simon  

Aysenia Tullgren, 1902: 54   (type species by monotypy Aysenia elongata Tullgren, 1902   ). Simon, 1903 a: 1031. Ramírez, 1995 a: 381 (transferred from Clubionidae   ), 1997: 178, 2003: 60.

Diagnosis: Species of Aysenia   are similar to those of Aysenoides   in having an elongate body, a recurved posterior eye row, and the third leg directed forward ( Fig. 1 View FIGURE 1 a, Ramírez 2003: figs 24 a and 28 d), but can be distinguished by having irregular spermathecae (instead of spherical, Ramírez 2003: figs 22 c and 29 d), and an unmodified, flattened embolar process (instead of spine-like) ( Fig. 4 View FIGURE 4 b, Ramírez 2003; figs 27 b).

Description: See Ramírez (2003), additional characters are here presented: Prosoma wide in front, some species with cephalic area as wide as thoracic area ( Fig. 8 View FIGURE 8 a), other slightly narrower anteriorly. Posterior eye row recurved, except in A. huayun   n. sp., ocular area projecting ( Fig. 11 View FIGURE 11 d). Color reddish-brown except A. elongata   which are pale, and characteristic opisthosoma color pattern in each species (spots in A. araucana   , A. cylindrica   , A. grismadoi   n. sp., A. izquierdoi   n. sp. and A. huayun   n. sp.; chevrons in A. segestrioides   and A. barrigai   ; arrow with chevrons in A. elongata   ). Male paramedian apophysis with two or three cusps. Secondary conductor small or absent. Embolus variable in length, with basal process flattened ( Figs 4 View FIGURE 4 b, 9 e). Epigyne with large accessory bulbs ( Figs 6 View FIGURE 6 b, 13 d).

Distribution: Southern forests of Chile and Argentina.
