Type. Holotype male: MEXICO: Guanajuato: Municipality of Acámbaro , Sierra de los Agustinos, pitfall trap, 25.III.2006, A.F. Quijano, J. Ponce, and M. Villaseñor (CNAN-T1124), deposited at CNAN .

Etymology. The specific name is a patronym in honor of Javier Ponce Saavedra, one of the collectors of the holotype, for his contribution to Arachnology in Mexico.

Diagnosis. The males of this species differ from N. dentata and N. leonensis in having the RTA with dorsal and ventral projections short and not clearly differentiated ( Fig. 34 e). The females differ from N. ajusco , N. leonensis , and N. dentata in having the atrium with anterior margin less sclerotized, from N. alvarezi in having the atrium with posterior margin straight, and from N. atzimbo in having the atrium procurved ( Fig. 34 f).
