Figs 11a–c, 18b, 22c–d, 27
Type. Holotype: male from Sector Los Hoyos, Vereda Avendaños, Sotaquirá, Boyacá, Colombia, 2941 m [5.845722°N, 73.302444°W], 04.VI.2015, Y. Cifuentes, J. Moreno (ICN –Ar 7981).
Etymology. The epithet, to be treated as a Latin adjective, refers to an indigenous people of the Chibcha language family, the Sotairas people, who inhabited the region of the type locality.
Diagnosis. Males of A. sotairensis sp. nov. are similar to those of A. semicanus (Simon, 1902) and A. zaque sp. nov., by the shape of the RTA. However, they can be recognized from those and the remaining species in the genus by their large bilobated RTA, with the dorsal lobe wide and rounded, the presence of a slender retrolateral patellar apophysis (RPA), a proventral femoral widening (PvFw) hidden by tegular lobe (TL), basal embolic apophysis (BEA), and basal widening of the embolus (bwe) (Figs 11a–c, 22c–d).
Description. Male (holotype). Total length: 3.21. Carapace light brown with two dark brown parallellongitudinal stripes, 1.57 long, 1.10 wide, 0.77 high (Fig. 18b). OC dark brown with white hairs and in the sides with dark orange hairs, 0.61 long. Anterior eye row 1.16 wide and posterior 0.98 wide. Sternum 0.64 long, 0.50 wide, yellow. Labium 0.22 long, 0.46 wide, yellow. Chelicerae yellow with three retromarginal and two promarginal teeth. Palp yellow with brown cymbium, a large single bilobate RTA, presence of a retrolateral patellar apophysis (RPA), a pointed proventral femoral widening (PvFw) hidden by rounded tegular lobe (TL) (black arrow), slender embolus with basal embolic apophysis (BEA), and basal widening (bwe) (Figs 11a–c, 22c–d). Legs 4312, all yellow, with metatarsus I y metatarsus–tarsus II–III brown. Leg macrosetae: femur, I, IV d 1 di; II–III d 2 di; patella, III–IV r 1 me; tibia, I v 2-2 -2; II v 1 -0-2, p 1 me, r 1 me; III–IV v 1 -0-1, p 1-1, r 1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 1 -0-2, p 1-1, r 1-2; IV 1 -0-2, p 1-0-2, r 1-1-2. Abdomen light brown with a brown reticulated pattern of stripes (Fig. 18b).
Female. Unknown.
Comments. The holotype male was collected in a pitfall trap, in an intervened high-Andean wet forest. The inclusion of A. sotairensis sp. nov. in the genus Amphidraus is based partially in the general morphology of the sexual characters, but the presence of retrolateral patellar apophysis (RPA), proventral femoral widening (PvFw), and basal embolic apophysis (BEA) may indicate a distinct lineage, or these characters could represent an autapomorphy of the species. This hypothesis will be tested in future research when more specimens are available to morphology and molecular studies.
Distribution. Colombia (Boyacá) (Fig. 27). Known altitudinal distribution: 2941 m.
