Types. Holotype male of N. intermedia : USA: California: La Honda , 37°20′N, 122°17′W, 4.XI.1922, J.C. Chamberlin, deposited at AMNH (examined) . Holotype female of N. pina : USA: California: Echo Lake , 38°08′N, 120°52′W, VII.1934, L.W. Saylor, deposited at AMNH (examined).

Synonymy justification. The overall appearance of the epigynum of N. pina is as in N. intermedia , in shape and position of spurs, copulatory ducts, primary and secondary spermathecae, as well as the protrusion of anterior margin of atrium.

Diagnosis. The males of N. intermedia distinguish from all species in having the RTA with dorsal projection large and cupped ( Figs. 10 c, 11b). The females are similar to N. ajusco , N. alvarezi , N. dentata , and N. leonensis , but differ from those species in having the atrium with anterior margin not sclerotized ( Fig. 11 c).

Description. Male (holotype): Carapace light brown. Chelicerae dark brown, condyles brown. Endites brown with white tips. Labium dark brown with white tip. Sternum brown.
