Types. Holotype: male from Reserva Natural La Almenara , Santa María, Boyacá, Colombia, 1126 m, 4.87907°N, 73.25333°W, 6.XII.2016, R. Anderson ( ICN –Ar 8273)GoogleMaps  . Paratypes: one female with same data as holotype ( ICN –Ar 8274). One male paratype with the same locality as holotype, 1152 m, 4.88749°N, 73.24989°W, 7.XII.2016, R.

Etymology. The epithet is a noun in apposition that honors Chíe  , the goddess of moon (also known as Chía) in the Muisca mythology, indigenous people that inhabited the region where the species was found, in the central Andean highlands of the present-day Colombia's Eastern Range.

Diagnosis. Males of A. chie  sp. nov. can be easily distinguished from those of the remaining species of the genus by their smaller body size and darker coloration, the double-pointed RTA ( Figs 2a –bView FIGURES 2, 20c –dView FIGURES 20). Females of A. chie  sp. nov. are similar to those of A. bochica  sp. nov. and A. sikuani  sp. nov. by the short copulatory ducts, but can be distinguished from those by the fact that the copulatory ducts connect proximally to the spermathecae, and posterior concave border of the epigynal plate ( Figs 2c –dView FIGURES 2, 24b, 24hView FIGURES 24).

Description. Male (holotype). Total length: 1.81. Carapace black, 1.06 long, 0.78 wide, 0.57 high ( Fig. 16cView FIGURES 16). OC black, 0.54 long. Anterior eye row 0.85 wide and posterior 0.77 wide. Sternum black, 0.46 long, 0.34 wide. Labium black, 0.09 long, 0.17 wide. Chelicerae black with four retromarginal and two promarginal teeth. Palp black and extremely small, with a long and bifurcated-tipped RTA, and long and rounded tegular lobe (TL), rounded embolic disc (ED), and a short embolus with basal widening (bwe) ( Figs 4a –bView FIGURES 4, 20c –dView FIGURES 20). Legs 4312, all black, with the I –II with metatarsus –tarsus yellowish, and III –IV with femur –tarsus with yellow marks. Leg macrosetae: femur, I –IV d 1 di; tibia, I v 2-2 -2; II v 1-1 -2; III –IV v 1 pr, p 0-1-1, r 0-1-1; metatarsus, I v 2-2; II v 2- 2, p 1 di; III v 1 di, p 1-0-1, r 2 di; IV v 1 -0-1, p 1-0-2, r 2 di. Abdomen black with transversal thin cream-colored stripes, and two pairs of lateral and posterior white spots ( Fig. 16cView FIGURES 16).

Variation (n= 2 males). Total length 1.81–1.84. Carapace length 1.05–1.06.

Female (paratype, ICN –Ar 8274). Total length 2.42. Carapace dark brown with posterior side with black wide marks, 1.12 long, 0.76 wide, 0.57 high ( Fig. 16dView FIGURES 16). OC black, 0.57 long. Anterior eye row 0.82 wide and posterior 0.77 wide. Sternum yellow, 0.49 long, 0.37 wide. Labium yellow, 0.14 long, 0.18 wide. Chelicerae yellow, with four retromarginal and two promarginal teeth. Legs 4312, all yellow. Leg macrosetae: femur, I –II, IV d 1 di, III d 2 di; tibiae, I v 2-2 -2; II v 2-2 -2, p 1 di; III v 1 pr, p 0-1-1, r 0-1-1; IV v 1 -0-1, p 1 di, r 1-0-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 1 pr, p 1-0-2, r 1-0-1; IV v 1 -0-1, p 1-0-2, r 1-0-1. Abdomen black with transversal thin cream-colored stripes, and two pairs of lateral and posterior white spots, and two anterior and dorsal gray stripes ( Fig. 16dView FIGURES 16). Epigyne ( Figs 2c –dView FIGURES 2, 24b, 24hView FIGURES 24) with anterior and wide copulatory openings, short copulatory ducts, rounded posterior spermathecae, and concave posterior border of the epigynal plate.

Comments. The type material was collected in Winkler traps, in a secondary Andean forest, at the same locality where the type specimens of A. sua sp. nov. were collected, so here they are considered to be sympatric. It is interesting to point out that this species was collected in the same sample with numerous specimens of an undescribed species of the genus Tenedos O. Pickard-Cambridge, 1897  ( Zodariidae  : Stonerinae), which presented a similar pattern of coloration.

Distribution. Colombia (Boyacá) ( Fig. 27View FIGURE 27). Known altitudinal distribution: 1126–1152 m.
