Diagnosis. Thorax: basal third of corium convex, surpassing the imaginary line tangencial to humeral angles ( Fig. 3A 2 ), shared with N. soror ; ostiolar ruga long, anterior margin curved, apex pointed ( Fig. 3 D ). Abdomen: urosternites with black maculae, diameter shorter than spiracles, as in N. capicola ; median tubercle of third urosternite well developed attaining mesocoxae ( Fig. 3A 1 ), character exclusive of this species, but also present in some species of Chinavia . Male: ventral rim of pygophore with brims developed towards middle, continuous at mid line ( Fig. 8H ), shared with N. naspira and N. mendax ; paramere trilobate, lobes well developed. Female: posterior margins of gonocoxites 8 straight; longitudinal sutures of gonocoxites 8 absent ( Fig. 16 H ), condition exclusive to this species; basal half of laterotergites 9 laterally concave and medially convex; ductus receptaculi, after vesicular area, longer than three times the length of pars intermedialis ( Fig. 18 C ), shared with N. capicola and N. soror .
