Type. Holotype male: MEXICO: Oaxaca: La Cumbre, Highway Oaxaca-Tuxtepec, 42 km N Oaxaca, 2800 m, 16.IX.2000, E. González, O. Delgado, J. Castelo, E. Lira, J. Lira, C. Durán, O. Grosselet, and M. Grosselet (CNAN-T1019), deposited at CNAN.
Etymology. The specific name is a noun in apposition taken from the state of the type locality.
Diagnosis. The males of N. oaxaca differ from N. gibarrai in having the tegular median process straight (Fig. 32 a), and from N. perote by the absence of a ventral projection on the RTA (Fig. 32 b). The females differ from N. attenuata in having the posterior margin not protruded (Fig. 32 c), from N. gibarrai in having the copulatory ducts curved in lateral direction (Fig. 32 d), and from N. perote in having the atrium without two pairs of sclerotized sharp tips (Fig. 32 c).
Description. Male (holotype): Carapace brown, white feathery scales on cephalic region. Chelicerae dark brown, condyles brown. Endites and labium brown with white tip. Sternum dark brown with an orange central spot. Legs orange with three rings on femur. Opisthosoma dark brown with dark brown foliage and five pairs of black spots. Spinnerets yellow. Total length 6.25. Carapace length 3.13, width 2.14, cephalic region width 1.24, ocular region width 0.67. Eye diameter: AME 0.1, ALE 0.13, PME and PLE 0.15.

Chelicerae with three retromarginal teeth; basal segment length 1.21, fang length 0.61. Labium wider than long (0.52/0.39). Endites convergent (distance at their base compared at their tips 0.52/0.21). Sternum longer than wide (1.67/1.36). Opisthosoma longer than wide (2.88/1.88).

Number of trichobothria on tarsus: I—6, II—6, III—6, IV—6. Number of dorsal spines on pedipalp: femur 3, tibia 3. Cymbium length 1.09, width 0.58.
