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

Diagnosis. This species differs from N. shlomitae , N. simplex , and N. gibarrai , and N. irazu in having the atrium with posterior margin divided in two large and rounded parts ( Fig. 43 a), and from N. cintalapa and N. tacana in having the median plate wider towards the ventral margin ( Fig. 43 c).

Description. Female (holotype): Carapace brown. Chelicerae reddish, condyles orange. Endites and labium dark brown with white tips. Sternum yellow with dark brown border. Legs with three rings on femur. Opisthosoma brown with several yellow spots and dim foliage. Spinnerets orange. Total length 11.25. Carapace length 5.38, width 3.38, cephalic region width 2.24, ocular region width 1.1. Eye diameter: AME 0.17, ALE and PME 0.23, PLE 0.27.

Chelicerae with three to four retromarginal teeth; basal segment length 1.97, fang length 0.91. Labium wider than long (0.7/0.61). Endites almost convergent (distance at their base compared at their tips 0.7/0.3). Sternum longer than wide (2.29/1.81). Opisthosoma longer than wide (5.88/3.75). ALS separated by less their basal diameter (0.29/0.48), PLS with distal segment slightly longer than basal segment (0.83/0.77).

Number of trichobothria on tarsus: I—8, II—8, III—?, IV—?. Dorsal spines on pedipalp femur: 3. Prolateral spines on tibia: 2-2. Epigynal plate wider than long (1.31/0.92); atrium in shallow depression with posterior margin strongly sclerotized and with two large and rounded borders; anterior hyaline spurs separated by more their basal width ( Fig. 43 a, c).
