Diagnosis. Males most resembles N. ruffoi sp. nov. but are distinguished by their bulb with shorter not serrated PAC keel ( Fig. 9E View FIGURE 9 ) while PAC keel large and serrated in the latter ( Fig. 6E View FIGURE 6 ). Females most resembles N. ruffoi sp. nov. and N. caxiuana ( Pérez-Miles et al. 2008) but are distinguished from N. ruffoi sp. nov. by the basal atrium with a triangular transparent middle region ( Fig. 10D, E View FIGURE 10 , arrow) while basal atrium with medially transparent rectangular region ( Fig. 7D, E View FIGURE 7 ); from N. caxiuana by spermathecae head oval ( Fig. 10D, E View FIGURE 10 ) spermathecae head elongated in the latter ( Pérez-Miles et al. 2008: fig. 9).

Etymology. The specific epithet is a non-Latin adjective (invariable) that honors the people of San Francisco de las Pampas for their fight against the mining industries and their efforts to preserve natural resources.
