Figs. 8 –10 View FIGURE 8 View FIGURE 9 View FIGURE 10 , 22 View FIGURE 22 b, 23 d–f, 24 d–f

Type material: Holotype: male from Chile, Región IX (Araucanía), Cautín province, Bellavista   , N shore Lago Villarrica, ca. 39 º S, 72 º W, 310 m, site 655, window trap, Valdivian rainforest, 15–30 December 1982, A. Newton & M. Thayer ( AMNH; temporary preparations male: VIW-00002, VIW-00003, female: MJR- 0 1337, VIW-00004). Paratype: female, same data as holotype.

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

Diagnosis: Females can be distinguished by their epigyne having an anterior trapezoidal sclerotized area, leaving the posterior margin of the epigyne mostly unsclerotized ( Fig. 10 View FIGURE 10 c). Males are similar to several other Coptoprepes   by having a RTA curved, longer than the tibia ( Fig. 10 View FIGURE 10 c), but can be distinguished from them by the truncate tip of the primary conductor and from the similar C. contulmo   n. sp. by having a ventrally concave secondary conductor ( Figs. 10 View FIGURE 10 b–f, 23 -d–f).

Description: Male (holotype): Prosoma length 2.07, width 1.55, narrower in front than in the female. Ttibia/metatarsus length: I, 1.43 / 1.33; II, 1.20 / 1.32; III, 0.92 / 1.17; IV, 1.28 / 1.70. Chelicerae slightly smaller than those of female, with six (right) or seven (left) teeth on retromargin, four on promargin. Sternum length 1.13, width 0.83. Spines: leg I, femur d 1 - 1 - 1, p d 1 ap; tibia v 2 - 2 - 2; metatarsus v 2 bas. II, femur d 1 - 1 - 1, p and r d 1 ap; tibia v r 1 -r 1-2; metatarsus v 2 bas. III, femur d 1 - 1 - 1, p 0-d 1 -d 1 or d 1 ap, r d 1 ap; 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-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 or left 2 - 2 -(p 1-2), p 1 -d 1 - 1 -0, r 1 -d 1 - 1 -0 or left 1 -d 1 -d 1 - 1; metatarsus v 2 - 2 -comb or left r 1-2 -p 1 -comb, p and r d 1 - 1 - 1 or left p d 1 - 1 - 1 - 0-1, d 0-p 1-2 (left leg seemingly abnormal, not considered for scoring of dataset). Opisthosoma length 2.17, spiracle–epigastrium 1.21, spiracle– spinnerets 0.24. Color in ethanol ( Fig. 8 View FIGURE 8 ): As in female, but paler, specimen slightly faded. Palp ( Fig. 10 View FIGURE 10 ): Tibia short, width/length 1.58, RTA longer than tibia, curved, compressed. Cymbial conductor wide. Tegulum displaced basally in ventral view, mostly visible in retrolateral view. Sperm duct with conspicuous loop on anterior-dorsal margin. Embolus long, with flat, rounded basal process. Median apophysis wide, truncate, translucent. Primary conductor with canal, ending in truncate sclerotized projection. Secondary conductor ventrally concave, well sclerotized, separated from anterior-dorsal sperm duct loop by a membranous stripe. Paramedian apophysis with prolateral-ventral cusp (pPMA, Fig. 23 View FIGURE 23 d–f) and a series of several short cusps (rPMA).

Female (paratype): Prosoma length 2.10, width 1.37. Length of tibia/metatarsus: I, 0.98 / 0.85; II, 0.88 / 0.82; III, 0.78 / 0.90; IV, 1.25 / 1.42. Chelicerae with five teeth on retromargin, four on promargin. Sternum length 1.05, width 0.83. Spines: leg I, femur d 1 - 1 - 1, p 2 ap; tibia v 2 - 2 -p 1; metatarsus v 2 bas. II, femur d 1 - 1 - 1, p 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 1 -d 1 - 1 -0 or 0-d 1 - 1 -0, d r 1 bas; metatarsus v 2 -0-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 - 2 plus apical comb, p d 1 - 1 - 1, r d 1 - 0-1, d 0-2 - 2. Color in ethanol ( Fig. 9 View FIGURE 9 ): Prosoma brown, legs brown, darker distally. Opisthosoma pale brown with dorsal pattern brown, with weakly defined posterior chevrons. Opisthosoma length 2.70, epigastrium–spiracle 1.32, spiracle–spinnerets 0.18. Epigyne: Trapezoidal sclerotized patch, mostly anterior to internal ducts. Lateral lobes separate, posterior half not sclerotized except at the limits with the median field. Median field weakly sclerotized ( Fig. 10 View FIGURE 10 g). Copulatory openings very close to epigastric furrow. Copulatory ducts not wrapped. Ducts of accessory bulbs short. Spermathecae with convoluted chambers, fertilization ducts well separated from posterior margin of epigyne ( Figs. 10 View FIGURE 10 h, 24 d–f).

Variability: Spines in females: I, tibia v 2 - 2 -0. Spines in males: III, tibia v p 1-2 - 2.

Distribution: Known for Cautín and Ranco provinces in Chile.
