Figs 9a–d , 17f–g , 21j–k , 24f, 24l , 27

Types. Holotype: male from Finca Suasie , Vereda Rincón del Oso, Guasca, Cundinamarca, Colombia, 3090 m, 4.71725°N, 73.866166°W, 13.IX.2014, D. Martínez ( ICN –Ar 8254) . Paratype: one female with same data as holotype ( ICN –Ar 8255).

Etymology. The epithet is a noun in apposition that honors Sie, the goddess of water, 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. sie sp. nov. can be easily distinguished from those of the remaining species of the genus by their long, three pointed RTA ( Figs 9a–b , 21j–k ). Females are similar to those of A. mae sp. nov., A. somondoco sp. nov. and A. sua sp. nov. by their general disposition of internal structures of the epigyne, but can be distinguished by their shorter copulatory ducts, with pear-shaped spermathecae, larger epigynal plate with anteromedial copulatory openings and a posterior single medial pocket (po) ( Figs 9c–d , 24f, 24l ).

Description. Male (holotype). Total length: 2.60. Carapace yellowish brown with a lighter dorsal and posterior mark, 1.53 long, 0.93 wide, 0.72 high ( Fig. 17f ). OC black, 0.60 long. Anterior eye row 0.98 wide and posterior 0.89 wide. Sternum yellow, 0.57 long, 0.45 wide. Labium yellow, 0.14 long, 0.20 wide. Chelicerae yellow with three retromarginal and two promarginal teeth. Palp yellowish brown with distal femur and patellae with long white hairs, with a long and three-pointed RTA, and long tegular lobe (TL) ( Figs 9a–b , 21j–k ). Legs 4312, all yellowish brown. Leg macrosetae: femur, I–II, IV d 1 di; III d 2 di; tibia, I v 2-2 -2; II v 1-2 -1, p 1 di; III–IV 1 -0-1, p 1-0-1, r 1-0-1; metatarsus, I–II v 2-2; III v 1 -0-1, p 1-0-2, r 1-0-2; IV v 1 -0-1, p 1-0-2, r 1-1-2. Abdomen dehydrated, but gray in color ( Fig. 17f ).

Female (paratype, ICN–Ar 8255). Total length 4.42. Carapace yellow with two posterior dark brown longitudinal stripes, 1.88 long, 1.31 wide, 0.99 high ( Fig. 17g ). OC dark brown, 0.74 long. Anterior eye row 1.27 wide and posterior 1.20 wide. Sternum yellow, 0.79 long, 0.63 wide. Labium yellow, 0.20 long, 0.25 wide. Chelicerae yellow, with four retromarginal and two promarginal teeth. Legs 4312, all yellow, III–IV with dark brown patches on tibiae–tarsi. Leg macrosetae: femur, I–IV d 1 di; patellae, III–IV r 1 me; tibiae, I v 2-2 -2; II v 2- 2 -2, p 1 di; III v 1 pr, p 1-0-1, r 1-0-1; IV v 1 pr, p 1-0-1, r 1-1-0; metatarsus, I–II v 2-2; III v 2 -0-1, p 1-0-2, r 1-0- 2; IV v 1 di, p 1-0-2, r 1-0-2. Abdomen brown with a gray longitudinal stripe ( Fig. 17g ). Epigyne ( Figs 9c–d , 24f, 24l ) with anterior and medial copulatory openings, long copulatory ducts, a posterior single medial pocket, and medial slender pear-shaped spermathecae.

Variation (n= 2 females). Total length 4.34–4.42. Carapace length 1.88–1.91.

Comments. The type material was collected in a pitfall trap in an intervened Andean Ecosystem.

Distribution. Colombia (Cundinamarca) ( Fig. 27 ). Known altitudinal distribution: 3090 m.
