Type. Holotype male: MEXICO: Jalisco: Municipality of Guadalajara, 12.9 km W Guadalajara, 20°44′N, 103°29′W, 13.V.1963, W.J. Gertsch and W. Ivie, deposited at AMNH GoogleMaps .

Etymology. The specific name is a patronym in honor of Ralph V. Chamberlin for his contribution to the taxonomic knowledge of the family Agelenidae .

Diagnosis. The males of this species differ from N. iviei in having the RTA without ventral projection ( Fig. 17 View FIGURE 17 b). The females differ from N. plata and N. prieta in having the atrium with posterior rounded projections ( Fig. 17 View FIGURE 17 e).
