Type material. Holotype 3 (CNC): PERU. Madre de Dios: Avispas, 400 m. 10–20.ix.1962 / L. Peña, Holotype 3 [type number 9927]. Condition of holotype: good, not dissected. The type of Neoscutops peruvianus was not examined, but high quality photographs were provided by Dr. J. Cumming, CNC, which allowed the secure identification of specimens, since this species is somewhat conspicuous and easily recognizable.

Etymology. The specific name makes reference to Huaorani (Waorani), the indigenous people in the Amazon region of Ecuador. Huaorani (Waorani) means “humanos (humans) in the language spoken by the Huaorani.
Comments. The species is similar to Neoscutops flavoscutellatus sp. nov. and Neoscutops manaos sp. nov. in the inverted W-shaped spot on the face. However, it differs from them in the coloration of the clypeus, scutellum and femora, plus characters of the male and female terminalia.
