Figs. 17 –18 View FIGURE 17 View FIGURE 18 , 22 View FIGURE 22 e, 24 j–l

Type material: Holotype: female from Chile, Región XII (Magallanes y Antártica), Ultima Esperanza province, Puerto Eden   , Isla Wellington, ca. 49 ° S 74 ° W, 7–9 December 1962, P. J. Darlington ( MCZ; temporary preparation MJR-01344, VIW-00012).

Etymology: The specific name is a noun in apposition taken from the type locality.

Diagnosis: Females are similar to that of C. casablanca   n. sp. by having the lateral lobes of the epigyne posteriorly concave, continued in a pouch leading to the copulatory openings ( Fig. 23 View FIGURE 23 ), but can be distinguished by the smaller, irregularly shaped spermathecae ( Fig. 24 View FIGURE 24 j–l). Males are still unknown.

Female (holotype): Prosoma length 3.03, width 1.93. Tibia/metatarsus length: I, 1.49 / 1.34; II, 1.41 / 1.31; III, 1.24 / 1.57; IV, 1.80 / 2.26. Chelicerae with five or six teeth on retromargin, four or five on promargin (right side with more teeth). Sternum length 1.51, width 1.21. Spines: leg I, femur d 1 - 1 - 1, p 2 ap; tibia v p 1-2 -p 1; metatarsus v 2 bas. II, femur d 1 - 1 - 1, p d 1 ap; tibia v 0-r 1 -p 1, p 0-1 or 0; metatarsus v 2 bas. III, femur d 1 - 1 - 1, p and r 0-d 1 -d 1; patella r d 1; tibia v p 1-2 - 2 (median pair not well paired), d r 1 bas, p and r 1 -d 1 - 1 -0; metatarsus v 2 - 2 -comb, d 0-p 1-2, p and r d 1 - 1 - 1. IV, femur d 1 - 1 - 1, p 0-d 1 -d 1, r d 1 ap; patella r d 1; tibia v p 1- 2 - 2, d 2 bas, p and r 1 -d 1 - 1 -0; metatarsus v 2 - 2 -p 1 plus apical comb, d 0-2 - 2, p and r d 1 - 1 - 1. Color in ethanol ( Fig. 17 View FIGURE 17 ): Brown uniform, venter of opisthosoma paler. Opisthosoma length 3.79, epigastrium–spiracle 1.54, spiracle–spinnerets 0.39. Epigyne: Central area anterior to median field not sclerotized. Lateral lobes separated from median field, concave, continued in pouch to copulatory openings, close to epigastric furrow. Median field posteriorly sclerotized, slightly elevated ( Fig. 18 View FIGURE 18 a). Copulatory ducts slightly wrapped on transversal-oblique axes. Ducts of accessory bulbs well defined. Spermathecae irregular, connate, with ample lumen ( Figs. 18 View FIGURE 18 b, 24 j–l).

Distribution: Only known from the type locality.

Other material examined: None.
