Type. Holotype male: MEXICO : Mexico City: Parque Nacional Desierto de los Leones, 2743–3048 m, 6.IV.1946, J.C. Pallister and D.L. Pallister, deposited at AMNH .

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

Diagnosis. The males of N. leonensis differ from all species in having the RTA with dorsal projection large and pointed ventrally ( Fig. 30 d, e). The females differ from N. bipunctata , N. intermedia , and N. alvarezi in having the atrium with anterior margin sclerotized, from N. ajusco in having the spurs less projected ventrally ( Fig. 30 h), and from N. dentata in having the spurs adjacent ( Fig. 30 f) and primary spermathecae without a dorsal transverse mark ( Fig. 30 g).
