Type material. Male holotype from Chile, Antofagasta Region (II), Antofagasta Province, 8.1 km NNW Paposo , 24.93947º S, 70.49265º W, elev. 114 m, 27–29 Oct 2011, M.J. Ramírez, A. Ojanguren, J. Pizarro et al. (temporary preparations AJL-1 to 6; AJL-10; AJL-15), deposited in MNHN. Same data, male paratype, MACN-Ar 30292 (temporary preparation MJR-1405). Female paratype together with holotype.
Etymology. The specific name is a noun in apposition taken from the type locality.
Diagnosis. It is similar to Aysenia araucana Ramírez by having moderately wrapped copulatory ducts, long embolus and relatively small primary conductor, but can be distinguished by the long extension of the primary conductor in retrolateral view (shorter in Aysenia araucana ), and the angle of the margin of tegulum and cymbium of about 90° in retrolateral view ( Fig. 1 View FIGURE 1 d) (about 120° in Aysenia araucana, Ramírez 2003 : fig. 25B), and the leftright copulatory ducts in the female vulva well separated, less coiled ( Fig. 2 View FIGURE 2 c) (contiguous and clearly coiled in Aysenia araucana, Ramírez 2003 : fig. 25E).
Description. Male (holotype): Prosoma length 1.93, width 1.03, narrowed in front ( Fig. 1 View FIGURE 1 a). Tibia/metatarsus length: I, 1.23/1.07; II, 1.07/1.00; III, 0.60/0.70; IV, 1.13/0.83. Chelicerae strong, with thick anterior bristles ( Fig. 1 View FIGURE 1 a) three contiguous teeth on retromargin and three on promargin. Sternum length 0.93, width 0.60. Spines: leg I, femur d 1-1-1, p d1ap; tibia v 2-2 -2 (the x-p 1-x displaced to prolateral), p 1-1-1 or 1-0-1, r 1-0-1; metatarsus v 2 -0- 2, p d1-d1-0-1, r 0-1-0, d 0-p1-0. II, femur = I; tibia v r1-r1-2, p d1-d1-d1; metatarsus v 2 -0-2, p d1-d1-0-1 or 0-d1- 0-1, d 0-1-0. III, femur d 1-1-1; tibia v 2 ap; d 2bas; metatarsus v 2 -r1-2 (x-r 1-x advanced); p 0-1-1; r 1ap; d 0-p1- 2. IV, femur = III; tibia v p1-p1-2, r 0-1-1; metatarsus v 2-2 -2, p d1-1-1, r d1-0-1; d 0-p1-2. Third legs directed forward. Opisthosoma length 2.33, spiracle–epigastrium 1.17, spiracle–spinnerets 0.30. Color in ethanol ( Fig. 1 View FIGURE 1 a, b): Prosoma brown, ocular region slightly darker. Chelicerae brown. Legs yellowish brown with coxae and trochanters slightly lighter. Labium, gnathocoxae and sternum dark brown. Opisthosoma brownish violet, dark, with three whitish dorsal spots, covered by white hairs, two patches of white hairs on posterior end. Venter dark brown. Palp ( Fig. 1 View FIGURE 1 a, b; 3a–c): tibia short, width/length 1.06, RTA sharp, long, thin. Cymbial conductor wide, triangular. Tegulum basal. Sperm duct with two loops at dorsal anterior margin. Embolous long, basal process flat, rounded. Median apophysis apical, thin, hook-shaped. Primare conductor long, with narrow apex. Secondary conductor rounded. Paramedian apophysis with three sclerotized cusps, close to median apophysis.
Female (paratype): Prosoma length 1.97, width 0.97, wider at chelicerae bases and at leg III. Length of tibia/ metatarsus: I, 0.83/0.70; II, 0.83/0.67; III, 0.50/0.53; IV, 0.87/0.67. Chelicerae strong, with thick anterior bristles, three teeth on retromargin, three on promargin. Length of sternum 0.93, with 0.60. Spines: leg I, femur d 1-1-1, p d1ap; tibia v 2-2 -2 (the x-p 1-x displaced to prolateral), p 1-1; metatarsus v 2 bas, p 0-d1-0. II, femur = I; tibia v r1- r1-2, p 1-0-1; metatarsus v 2 -r1-0, p 0-d1-0. III, femur d 1-1-1; tibia v 2 ap; d 2-p1-0; metatarsus v 2 -r1-2 (x-r 1-x advanced); p 0-1-0; r 1ap; d 0-p1- 2. IV, femur =III; tibia v p1-p1-2, r 0-d1-d1; metatarsus v 2 -p1-2, p 0-1-1, r d1-0- 1; d 0-p1-2. Third legs directed forward. Opisthosoma length 2.67, spiracle-epigastrium 1.37, spiracle–spinnerets 0.17. Color in ethanol ( Figs 2 View FIGURE 2 a, b): as in male. Epigyne: Lateral lobes elevated, slightly sclerotized, their limits with median field well defined ( Fig. 2 View FIGURE 2 d). Copulatory ducts coiled. Accessory bulbs with long ducts. Spermathecae irregular, separate ( Fig. 2 View FIGURE 2 c).
Variability. Spines in males: leg I, tibia r 0-1-0; metatarsus p 0-d1-0- 1. II, tibia p 0-d1-d1. Color of male specimen, photographed alive in the field: prosoma, ocular region and chelicerae black. Femur and patella black, covered with white hairs, tibia, metatarsus and tarsus lighter. Opisthosoma black, with three whitish dorsal spots, covered by white hairs and two patches of white hairs on posterior end ( Fig. 4 View FIGURE 4 ).
Natural history. Several specimens were collected in the coastal desert near Paposo , with abundant shrubs, in flowering time ( Fig. 4 View FIGURE 4 c). They were found beating and fogging Euphorbia lactiflua Phil. ( Fig. 4 View FIGURE 4 e), and on foliage and between rocks and leaf litter at the base of Heliotropium shrubs ( Fig. 4 View FIGURE 4 d, probably H. taltalense (Phil.) Jonhst ). No retreats could be observed.
Distribution. Only known from two localities of coastal desert in Antofagasta and Elqui provinces, separated by about 500 km.
