Coptoprepes contulmo new species

Figs. 15–16 , 22 d, 23j–l

Type material: Holotype: male from Chile, Región IX (Araucanía), Malleco province, Purén, Monumento Natural Contulmo , ca. 38º S, 73º W, 350 m, FIT, mixed evergreen forest, 11 December 1984 – 13 February 1985, S. & J. Peck ( AMNH; temporary preparations MJR-01333, VIW-00008).

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

Diagnosis: Females are still unknown. Males are similar to those of C. nahuelbuta by having a long and curved RTA and a large, heavily sclerotized secondary conductor, but can be distinguished by the smaller secondary conductor and the wide, flat, truncate median apophysis ( Figs 16 , 23 j–l).

Description: Male (holotype): Prosoma length 1.97, width 1.33. Tibia/metatarsus length: I, 1.37/1.25; II, 1.08/1.07; III, 0.85/1.07; IV, 1.25/1.52. Chelicerae with six teeth on retromargin, five on promargin. Sternum length 1.08, width 0.82. Spines: leg I, femur d 1-1-1, p 2 ap; tibia v 2-2 -2, p 1bas or 0; metatarsus v 2 bas. II, femur d 1-1-1, p d1ap; tibia v r1-2-2; metatarsus v 2 bas. III, femur d 1-1-1, p and r 0-d1-d1; patella r d1; tibia v p1-p1-2, d r1bas, p and r 1-d1-1-0; metatarsus v 2 bas plus apical comb, p and r d1-1-1, d 0-p1- 2. IV, femur d 1-1-1, p and r d1ap; patella r d1; tibia v p1-2-2, d r1bas, p and r 1-d1-1-0; metatarsus v 2-2 -0 plus apical comb, p and r d1-1-1, d 0-2-2. Opisthosoma length 2.07, spiracle–epigastrium 1.16, spiracle–spinnerets 0.19, with weak dorsal anterior scutum. Color in ethanol brown uniform, opisthosoma slightly paler ( Fig. 15 ). Palp ( Fig. 16 ): Tibia short, width/length 1.64, RTA longer than tibia, curved, compressed. Cymbial conductor wide. Tegulum basal in ventral view, mostly visible in retrolateral view. Sperm duct with conspicuous loop on anterior-dorsal margin. Embolus long, thin, basal process flat, rounded. Median apophysis wide, transparent, truncate. Primary conductor well sclerotized, with wide canal, apex short, moderately acute. Secondary conductor ventrally convex, well sclerotized, separated from anterior-dorsal sperm duct loop by membranous stripe. Paramedian apophysis with prolateral cusp globose, two retrolateral projections near median apophysis ( Fig. 23 j–l).

Female: Unknown.

Variability: Spines in males: IV, metatarsus, d 0-p1-2.

Distribution: Known from Malleco province in Chile.

Other material examined: CHILE: same data as holotype, 1 male ( AMNH; temporary preparation MJR- 01334); Chile, no specific locality, “loc. 59”, 1 male ( IRSN IG 25.765).
