The species was described in detail by Saether and Roque (2004: 67). The new material may contain more than one species as did also the type material (see Saether & Roque 2004: 68). Especially the specimens from Peruíbe appear somewhat intermediate between N. strixinorum and N. verruculata with gonocoxite slightly extended beyond the attachment point of the gonostylus. The male hypopygium and superior volsella are illustrated in Figures 22–24.

Distribution and biology. The species previously was known only from São Paulo State in Brazil. The new material extends the distribution to Santa Catarina State, as well as to Mexico. In Santa Catarina State it was collected at an altitude of about 1.800 m in a fragmented primary cloud forest belonging to the Mata Atlântica forest; in Mexico it was taken in a lowland rain forest at 130 m altitude.
