Type. Holotype female: MEXICO: Michoacán: Municipality of Quiroga, Mirador de Atzimbo, V.1943, F.H. Pough, deposited at AMNH.

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. This species differs from N. ajusco and N. leonensis in having the spurs separated by their basal width and from N. alvarezi, N. dentata, and N. poncei in having the atrium straight (Fig. 16 i).

Epigynal plate wider than long (0.83/0.54); atrium superficial with lateral margins strongly sclerotized; anterior sclerotized spurs separated by twice their basal width (Fig. 16 i, k). Internal genitalia: copulatory ducts straight; primary spermathecae adjacent (Fig. 16 j).
