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).
