Type. Holotype male: MEXICO: Chiapas: Municipality of Unión Juárez , Talquián , Volcán Tacaná Biosphere Reserve, 15°05′14.8″N, 92°05′55.6″W, 2100 m, pitfall trap, 9.VII.2007, D. Chamé and J.A. García, 1 ♂ (ECOTAAR 007691), deposited at ECOTAAR. GoogleMaps

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

Diagnosis. The males of this species differ from N. shlomitae in having the RTA with a conspicuous excavation ( Fig. 42 View FIGURE 42 b), from N. simplex in having the tegular median process less sclerotized ( Fig. 42 View FIGURE 42 a), from N. cintalapa in having a tegulum flat in lateral view ( Fig. 42 View FIGURE 42 b), and from N. gibarrai in having the tegular median process pointed ( Fig. 41 View FIGURE 41 e). The females differ from N. shlomitae , N. simplex , N. gibarrai , and N. irazu in having the atrium with posterior margin divided in two large and rounded parts, from N. cintalapa in having the spurs separated by two times their basal width ( Fig. 42 View FIGURE 42 c), and from N. triunfo in having the median plate uniformly wide ( Fig. 42 View FIGURE 42 e).
