Figures 23 , 24 a–c; Map 5

Type. Holotype female: MEXICO: Chihuahua: El Divisadero , 20.IV.1986, V. Roth and B. Roth (CASENT 9048888), deposited at CAS .

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

Diagnosis. This species differs from N. costata in having the atrium with lateral margins oblique ( Fig. 24 a), from N. creel in having the primary spermathecae straight and with a dorsal depression ( Figs. 23 a, 24b), and from N. durango by the absence of deep pits on atrium ( Fig. 24 a).

Description. Female (holotype): Carapace orange, cephalic region reddish with two longitudinal lines behind PME. Chelicerae reddish, condyles orange. Endites and labium brown with white tips. Sternum light brown with median yellow band. Legs with patella to metatarsus reddish; femur and tarsus orange. Three black rings on femur and two rings on tibia. Opisthosoma light brown with a dorsal black spot, two lateral orange bands, foliage, and several lateral black lines. ALS orange, PMS yellow, PLS yellow with black spots on distal segment. Total length 10.63. Carapace length 5.5, width 3.5, cephalic region width 2.25, ocular region width 1.25. Eye diameter: AME and PLE 0.15, ALE 0.23, PME 0.19. Distance between eyes: AME-AME 0.1, AME-ALE 0.15, AME-PME 0.25, ALE-PLE 0.1, ALE-ALE 0.48, PME-PME 0.19, PME-PLE 0.25. Clypeus height 0.4. Chelicerae with three to four retromarginal teeth; basal segment length 2.05, fang length 0.95. Labium wider than long (0.81/0.67). Endites almost straight (distance at their base compared at their tips 0.81/0.43). Sternum longer than wide (2.62/2.05). Opisthosoma longer than wide (5.38/3.38). ALS separated by less their basal diameter (0.27/0.48), PLS with distal segment shorter than basal segment (0.67/0.76).

Spination: femur dorsal I—1-2 -2/ 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 0/ ventral 2-2-2/ prolateral 1-1-0/ retrolateral 0; II—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; II—0/ 2-2-2/ 0-1-1/ 0-1- 1; III—2-2 -2/ 2-2-2/ 0-1-2/ 0-1-1; IV—1-2 -2/ 2-2-2/ 0-1-1/ 0-0-1. Number of trichobothria: I—6, II—7, III—7, IV—8. Dorsal spines on pedipalp femur: 3. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (1.61/ 0.82); atrium superficial with lateral margins strongly sclerotized; anterior sclerotized spurs separated by more their basal width ( Fig. 24 a, c). Internal genitalia: copulatory ducts straight, primary spermathecae almost adjacent with a dorsal depression ( Figs. 23 , 24 b).

Male. Unknown.

Variation. Body length 8.38–12.75; carapace length 4.25–5.75; patella-tibia I length 3.88–5.13 (n = 9).
