Type. Holotype male: MEXICO: Estado de México: Municipality of Villa de Allende, Parque Nacional Bosencheve , 19°25′N, 100°10′W, 7.V.1963, W.J. Gertsch and W. Ivie, deposited at AMNH .

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

Diagnosis. The males of N. mexiquensis differ from N. annamae in having the tegular median process with two projections, from N. dentata in having the tegular median process with projections adjacent, and from N. leonensis in having the tegular median process with projections of similar length ( Fig. 31 a) and the RTA with dorsal and ventral projections of similar size ( Fig. 31 b). The females differ from N. annamae in having the spurs separated from posterior margin by their length ( Fig. 31 c).
