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.
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 b). The females differ from N. plata and N. prieta in having the atrium with posterior rounded projections (Fig. 17 e).
