Type. Holotype: male from Estación Biológica Mosiro Itájura (Caparú), Lago Taraira, Taraira, Vaupés, Colombia, 200 m, 1.066667°N, 69.516667°W, II –IV.2004, J. Pinzón ( ICN –Ar 6775).GoogleMaps 

Etymology. The epithet is a noun in apposition and honors the indigenous people of the Tucanoan language family, the Tanimuca  people, which inhabits the Vaupés and Amazonas departments, in the low Apaporis river region, and whose language and culture are endangered.

Diagnosis. Males of A. tanimuca  sp. nov. are similar to those of A. guaitipan  sp. nov. and A. sikuani  sp. nov. by the shape of the RTA. However, they can be recognized from those by the presence of a laminar three-pointed RTA, longer embolus, rounded tegular lobe (TL) and very long embolic filament (EF) ( Figs 11d –fView FIGURES 11, 22iView FIGURES 22 –l).

Description. Male (holotype). Total length: 2.38. Carapace dark brown, 1.20 long, 0.94 wide, 0.61 high ( Fig. 18eView FIGURES 18). OC black 0.60 long. Anterior eye row 0.96 wide and posterior 0.86 wide. Sternum 0.53 long, 0.42 wide. Labium 0.12 long, 0.20 wide. Chelicerae with six tiny retromarginal and two promarginal teeth. Palp dark brown with femur and patella with long white hairs, and tibia with a laminar three-pointed RTA ( Figs 11e –fView FIGURES 11); bulb with a rounded tegular lobe (TL) and process on embolic disc (PED), and a long and curved embolic filament (EF) ( Figs 11dView FIGURES 11, 22iView FIGURES 22 –l). Legs 4312, all yellow with brown marks. Leg macrosetae: tibia, I v 2-2 -2; II v 1-1 -2, p 1 di; III v 1 me, p 1-1, r 1-1; IV v 1 pr, p 1-1, r 1-1; metatarsus, I v 2-2; II v 2-2, p 1 di; III v 1-2, p 1 di, r 2 di; IV v 1-2, p 1 di, r 1- 2. Abdomen brown with clear transverse stripes ( Fig. 18eView FIGURES 18).

Female. Unknown.
