Types. Three syntype females: COSTA RICA: 10°N, 84° W, F. Rogers, deposited at BMNH (examined).

Diagnosis. This species is similar to N. durango , N. divisadero , and N. creel by the general shape of the epigynum. It differs from N. durango in having the atrium covering one third of plate length and from N. divisadero and N. creel in having the atrium with lateral margins curved ( Fig. 7 f).

Description. Female (syntype): Carapace dark brown, cephalic region reddish. Chelicerae reddish, condyles orange. Endites and labium dark brown with white tips. Sternum dark brown with a posterior orange spot. Legs orange, tibia-metatarsus dark brown. Three black rings on femur and two on tibia. Opisthosoma dark brown with anterior brown spots and light brown foliage. ALS brown, PLS yellow. Total length 11.13. Carapace length 5.63, width 3.88, cephalic region width 1.9, ocular region width 1.14. Eye diameter: AME 0.19, ALE, PME, and PLE 0.23. Distance between eyes: AME-AME 0.1, AME-ALE 0.1, AME-PME 0.25, ALE-PLE 0.08, ALE-ALE 0.48, PME-PME 0.15, PME-PLE 0.17. Clypeus height 0.37. Chelicerae with three retromarginal teeth; basal segment length 2, fang length 0.9. Labium wider than long (0.81/0.67). Endites convergent (distance at their base compared at their tips 0.81/0.37). Sternum longer than wide (2.62/2.14). Opisthosoma longer than wide (5.5/3.63). ALS separated by less their basal diameter (0.24/0.45), PLS with distal segment as long as basal segment (0.61/0.61). Leg lengths: I—femur 3.88/ patella-tibia 4.88/ metatarsus 3.38/ tarsus 2; II—3.75/ 4.5/ 3.5/ 2; III—3.63/ 4.38/ 3.63/ 1.88; IV—4.5/ 5.63/ 4.88/ 2.13. Spination: femur dorsal I—1-2 -3/ II—1-3 -3/ III—1-3 -3/ IV—1-2 -3; patella I—dorsal 1-1/ prolateral 1/ retrolateral 0; II—1-1 / 1/ 0; III—1-1 / 1/ 1; IV—1-1 / 1/ 1; tibia I—dorsal 1-1-0/ ventral 2-2-2/ prolateral 1-1-0/ retrolateral 0; II—1-1 -0/ 2-2-2/ 1-1-0/ 0; III—1-1 -0/ 2-2-2/ 1-1-0/ 1-1-0; IV—1-1 -0/ 2-2-2/ 1-1-0/ 1-1-0; metatarsus I—0/ 2-2-2/ 0-1-1/ 0-0-1; II—0/ 2-2-2/ 0-1-1/ 0-0-1; III—2-2 -2/ 2-2-2/ 0-1-1/ 0-0-1; IV— 3-2 -2/ 1-1-1-2-2/ 0-1-1/ 0-0-1. Number of trichobothria on tarsus: I—6, II—6, III—7, IV—7. Dorsal spines on pedipalp femur: 4. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (1.39/0.91); atrium superficial with lateral margins strongly sclerotized; anterior sclerotized spurs separated by more their basal width ( Fig. 7 f, h). Internal genitalia: copulatory ducts straight, primary spermathecae adjacent with a dorsal depression ( Fig. 7 g).

Male. Unknown.

Variation. Body length 11.13–12.5; carapace length 4.88–6.25; patella-tibia I length 4.13–5.38 (n = 3). Distribution. COSTA RICA (unknown locality) (Map 6).
