The female genitalia of N. plumbea differ from its closest relative, N. atrata by the smaller size and the more elongate, entirely smoothly membraneous corpus bursae. The genitalia of N. plumbea are somewhat similar to those of N. notata , but the ductus bursae is narrower, the colliculum is shorter and much broader and the corpus bursae is more elongate.
