The labium extends to the base of abdominal segment III. The male genitalia of this species are most similar to those of  N. fenestrata, known only from Chile. The parameres ( Fig. 8E) of  N. fenestrataare similar but slightly broader, the median lobe is broader and more quadrate with the apex straight and without any indentation, and the lateral lobe ( Fig. 8F) is distinctly more slender and more tapered apically. In addition,  N. agnesis smaller ( 5.23– 5.70 mm), pale brown to brown with distinct small red spots dorsally, and the labium extends only to the apices of the hind coxae, whereas  N. fenestratais considerably larger ( 6.98–8.16 mm), usually strongly dark red with dark red dorsal spots showing through on palest specimens, and the labium extends well beyond the hind coxae to the base of abdominal segment III.
