For C.B. Wilson (1950, p.288) the females of N. aequalis and N. giesbrechti show similarities enough alike to make their separation difficult, but the males exhibit enough dissimilarity to make their separation imperative. This is an instance where both sexes are necessary to make satisfactory specific identification.
