Figure 16 i–k; Map 7

Type. Holotype female: MEXICO: Michoacán: Municipality of Quiroga, Mirador de Atzimbo , V.1943, F.H. Pough, deposited at AMNH .

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

Diagnosis. This species differs from N. ajusco and N. leonensis in having the spurs separated by their basal width and from N. alvarezi , N. dentata , and N. poncei in having the atrium straight ( Fig. 16 i).

Description. Female (holotype): Carapace dark brown. Chelicerae reddish, condyles orange. Endites and labium light brown with white tips. Sternum yellow. Legs yellow with black rings on femur. Opisthosoma light brown with several black spots. ALS dark brown, PLS light brown. Total length 5.38. Carapace length 2.86, width 1.86, cephalic region width 1.19, ocular region width 0.67. Eye diameter: AME 0.12, ALE, PME and PLE 0.15. Distance between eyes: AME-AME 0.04, AME-ALE 0.06, AME-PME 0.13, ALE-PLE 0.04, ALE-ALE 0.23, PME-PME 0.08, PME-PLE 0.08. Clypeus height 0.12. Chelicerae with three retromarginal teeth; basal segment length 1.12, fang length 0.48. Labium wider than long (0.45/0.3). Endites almost straight (distance at their base compared at their tips 0.45/0.24). Sternum longer than wide (1.43/1.1). Opisthosoma longer than wide (5.5/3.5). ALS separated by less their basal diameter (0.15/0.29); PLS with distal segment slightly shorter basal segment (0.35/0.38). Leg lengths: I—femur 1.9/ patella-tibia 2.29/ metatarsus 1.33/ tarsus 1.1; II—1.95/ 2.14/ 1.29/ 1; III— 1.81/ 2/ 1.67/ 1; IV—2.19/ 2.62/ 2.38/ 1.24. Spination: femur dorsal I—1-1 -2/ II—1-2 -3/ III—1-3 -3/ IV—1-1 -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/ 1-2-2/ 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/ 0; II—0/ 2-2-2/ 1-1-0/ 0; III—2-2 -2/ 2-2-2/ 0-0-1/ 0-0-1; IV—3-2 -2/ 2-2-2/ 0-0-1/ 0-0-1. Number of trichobothria: I—5, II—5, III—5, IV—6. Dorsal spines on pedipalp femur: 3. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (0.83/0.54); atrium superficial with lateral margins strongly sclerotized; anterior sclerotized spurs separated by twice their basal width ( Fig. 16 i, k). Internal genitalia: copulatory ducts straight; primary spermathecae adjacent ( Fig. 16 j).

Male. Unknown.

Variation. Body length 5.38–8.75; carapace length 2.86–3.75; patella-tibia I length 2.29–2.88 (n = 3).
