Type material: Holotype: male from Argentina, Río Negro province, Bariloche, ca. 41 º 0 0 S, 71 º 30 ’ W, March 1947, A. G. Giai (MACN-Ar 2218; temporary preparations MJR-01341, VIW-00014). Paratypes: female from Argentina, Neuquén province, Nahuel   Huapi Natl. Park, Lago Espejo, ca. 40 º 30 ’ S, 71 º 30 ’ W, 21 January 1985, M. J. Ramírez (MACN-Ar 20320; temporary preparations MJR-01342, VIW-00013).

Etymology: This new species is dedicated to V. Werenkraut’s colleagues and friends from Laboratorio Ecotono   , Bariloche, Argentina.

Diagnosis: Females are very similar to those of C. valdiviensis   by the rather flat epigyne with rectangular, unsclerotized median field ( Fig. 7 View FIGURE 7 g), but can be distinguished by having a longitudinally oriented profile of the anterior portion of the copulatory ducts ( Fig. 24 View FIGURE 24 a –c). Males are similar to those of C. campanensis   n. sp. by (virtually) lacking a RTA, but have a much smaller, not bifid median apophysis ( Figs. 7 View FIGURE 7 a –f, 23 a –c).

Description: Male (holotype): Prosoma length 1.86, width 1.36, narrower in front than in female. Tibia/ metatarsus length: I, 1.06 / 0.91; II, 0.92 / 0.84; III, 0.64 / 0.68; IV, 1.17 / 1.27. Chelicerae slightly smaller than those of female, with four teeth on retromargin, three on promargin (promargin observed from MACN-Ar 2227). Sternum length 1.05, width 0.78. Spines: I, femur d 1 - 1 - 1, p 2 ap; tibia v 0-2 -p 1; metatarsus v 2 bas. II, femur d 1 - 1 - 1, p d 1 ap; tibia v 0-r 1 -p 1; 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, p 1 -d 1 - 1 -0, r d 1 - 1, d 0; metatarsus v 2 -p 1-2 plus apical comb, p and r d 1 - 1 - 1, d 0-p 1- 2. IV, femur d 1 - 1 - 1, p 0-d 1 -d 1, r d 1 ap; patella r d 1; tibia v 2 - 2 - 2, p and r 1 -d 1 - 1 -0, d 0; metatarsus v 2 - 2 - 2 plus apical comb, p and r d 1 - 1 - 1, d 0-2 - 2. Opisthosoma length 2.20, spiracle –epigastrium 1.15, spiracle –spinnerets 0.18. Color in ethanol ( Fig. 5 View FIGURE 5 ): As in female, but paler, specimen faded (as well as male MACN-Ar 2227). Palp ( Fig. 7 View FIGURE 7 ): Tibia short, width/length 1.00, RTA reduced to short acute relict. Cymbial conductor wide. Tegulum only visible in retrolateral view. Sperm duct with conspicuous loop on anterior-dorsal margin. Embolus long, thin, basal process elongate, flat, transparent. Median apophysis thin, hook-shaped. Primary conductor with long canal, ventral border tiny, cuticular hair-like extensions, tip acute, elongate, directed forward. Secondary conductor well sclerotized, apical, without canal, contiguous to anterior-dorsal sperm duct loop. Paramedian apophysis absent, area only slightly sclerotized ( Fig. 23 View FIGURE 23 a –c).

Female (paratype): Prosoma length 1.82, width 1.29. Tibia/metatarsus length: I, 0.93 / 0.80; II, 0.83 / 0.78; III, 0.72 / 0.86; IV, 1.11 / 131. Chelicerae with four teeth on retromargin, four on promargin. Sternum length 1.05, width 0.76. Spines: leg I, femur d 1 - 1 - 1, p 2 ap; tibia v 2 - 2 - 2; metatarsus v 2 bas. II, femur d 1 - 1 - 1, p d 1 ap; tibia v r 1 -r 1 -p 1; 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 -p 1-2, p 1 - d 1 - 1 -0, r d 1 - 1, d r 1 bas; metatarsus v 2 -0-p 1 plus apical comb, p and r d 1 - 1 - 1, d 0-p 1- 2. IV, femur d 1 - 1 - 1, p and r d 1 ap; patella r d 1; tibia v p 1-2 - 2, p and r 1 -d 1 - 1 -0, d r 1 bas; metatarsus v 2 - 2 -p 1 plus apical comb, p and r d 1 - 1 - 1, d 0-p 1-2. Color in ethanol ( Fig. 6 View FIGURE 6 ): Prosoma brown, legs brown, darker distally. Opisthosoma pale brown, dorsal pattern brown, including posterior chevrons. Opisthosoma length 2.55, epigastrium –spiracle 1.19, spiracle –spinnerets 0.15. Epigyne: Lateral lobes separate, median field not sclerotized ( Fig. 7 View FIGURE 7 g). Copulatory openings very close to epigastric furrow. Copulatory ducts slightly wrapped. Ducts of accessory bulbs short. Spermathecae with convoluted chambers ( Figs. 7 View FIGURE 7 h, 24 a –c).

Variability: Spines in male: I, tibia v 0-p 1 -p 1. II, tibia v 0-2 -p 1. III, metatarsus v 2 -r 1-2 or 2 - 2 - 2.

Distribution: Known from Neuquén and Río Negro provinces in Argentina.

Other material examined: ARGENTINA: same locality as holotype, 1 male (MACN-Ar 2227; temporary preparation MJR-01343); same data as paratype [1 immature] (MACN-Ar).
