Etymology. The specific epithet refers to the Amazonian Rain Forest biome, where the species was found.  
Remarks. This new species differs from congeners by the chaetotaxy of the mid tibia with 3 pd median setae, postgonite with three basal setae, surstylus with 10–11 setae, distiphallus with median constriction, and ejaculatory apodeme very broad.
