Coptoprepes ecotono Werenkraut & Ramírez 2009: 9 View Cited Treatment (male holotype MACN-Ar 2218, female paratype excluded).

Note. Our analysis of the COI barcoding sequence indicates that a male with the characteristics of Coptoprepes ecotono (CASENT 9029781) share identical sequences with a still undescribed female. Both specimens were collected in the same locality in Chiloé, southern Chile, and have similar somatic morphology. Thus we consider them as conspecific. In comparison, the minimum distance we found between Coptoprepes species is 5.3%, between C. flavopilosus and C. bellavista . The female originally described as C. ecotono is here identified as C. laudani n. sp.

Emended diagnosis. Males are similar to those of C. campanensis by virtually lacking RTA, but can be distinguished by having the median apophysis smaller, not bifid ( Werenkraut & Ramírez 2009: figs 7A–F, 23A–C). Females are easily distinguished from those of all other Coptoprepes by having two small superficial pouches close to the epigastric furrow and spherical, contiguous spermathecae, with the copulatory ducts posterior to them ( Fig. 4 View FIGURE 4 ). Coptoprepes casablanca has roughly spherical spermathecae, but with the copulatory ducts lateral to them (see Werenkraut and Ramírez 2009: figs 24G–H).

Description. Male (holotype). Described in Werenkraut & Ramírez (2009: 9, figs 5, 7A–F, 23A–C).

Female (MACN-Ar 19397). Total length 5.19. Carapace length 2.39, width 1.60. Length of tibia/metatarsus I—1.00/0.87; II—0.93/0.87; III—0.80/0.93; IV—1.30/1.40. Palpal tarsus length 0.63. Chelicerae with three promarginal and four retromarginal teeth. Sternum length 1.30, width 0.93. Abdomen length 2.87, width 1.47. Tracheal spiracle 0.23 from spinnerets, 1.50 from epigastric furrow. Spines: leg I—femur d 1-1-1, p d2ap; metatarsus v 2 bas. II—femur d 1-1-1, p d1ap; metatarsus v 2 bas. III—femur d 1-1-1, p 0-d1-d1, r d1ap; patella r d1; tibia p 1-d1-1-0, r 0-d1-1-0, v p1-2-2; metatarsus d 0-p1-2, p and r d1-1-1, v 2 -0-(2+thick setae). IV—femur d 1-1-1, p 0-d1-d1, r d1ap; patella r d1; tibia p and r 1-d1-1-0, v 2-2 -2; metatarsus d 0-2-2, p and r d1-1-1, v 2-2 - (2+thick setae). Color in ethanol: Carapace and sternum reddish brown, legs lighter than prosoma. Dorsal abdomen light brown with symmetrical pattern of dark brown patches, ventral abdomen light brown. Sternum reddish brown, darker than legs ( Figs 3 View FIGURE 3 A–B). Epigyne with two superficial pouches close to epigastrium, spermathecae spherical, contiguous to each other ( Figs 3 View FIGURE 3 C, 4). Copulatory openings close to epigastrium ( Figs 3 View FIGURE 3 D, 4), accessory bulbs oriented posteriorly, connection with copulatory ducts apparently close to the beginning of the latter. Copulatory ducts describing a loop from dorsal to ventral at base of spermathecae. First portion of fertilization duct emerging from the base of spermathecae, running posteriorly ( Fig. 4 View FIGURE 4 ).

Variability. Rarely five teeth on promargin of chelicerae. Spines slightly variable between right-left sides. Ventral spines of metatarsus in females absent or r 1bas. Leg III—femur r 0-d1-d1; tibia r 1-d1-1-0; metatarsus d 0- 2-2, v x-2 -x or x-p 1-x. IV—femur p d1ap or none; tibia v p1-2-2. Frequently dorsal side of patella and tibia with long apical and basal bristles.

Distribution. Known from Nahuelbuta Natl. Park in Chile, Región IX (Araucanía) and Chiloé Island in Region X (Los Lagos), also in Río Negro province in Argentina.

Genetic barcoding. The COI sequence of a male (CASENT 9029781) is identical as one of the females (CASENT 9034099), and diverge 0.8% with the other female sequenced (CASENT 9034041). This group of sequences diverge 6.1% with the nearest neighbor, the only record of C. campanensis (MACN-Ar 28847).
