Figures 1 k, o, 28d, e; Map 5

Type. Holotype male: MEXICO: Jalisco: Municipality of Hostotipaquillo, NW Magdalena, 20°59′N, 104°02′W, 13.V.1963, W.J. Gertsch and W. Ivie, deposited at AMNH .

Etymology. The specific name is a patronym in honor of Wilton Ivie, one of the collectors of the holotype, for his contribution to the taxonomic knowledge of the family Agelenidae .

Diagnosis. This species differs from N. chamberlini in having the RTA with ventral projection and a deep excavation ( Fig. 28 e).

Description. Male (holotype): Carapace light brown, white feathery scales on cephalic region. Chelicerae dark brown, condyles orange. Endites and labium light brown with white tips. Sternum light brown with dark brown border. Legs light brown with three black rings on femur, one on patella, two on tibia, and one on metatarsus. Opisthosoma light brown with an anterior black spot, lateral black spots and foliage. Spinnerets light brown with basal segments dark brown. Total length 5.38.

Number of trichobothria: I—6, II—5, III—5, IV—6. Number of dorsal spines on pedipalp: femur 2, tibia 3. Cymbium length 0.96, width 0.58. Embolus curved; conductor with dorsal projection larger than ventral one; tegular median process with two short tips; RTA with a deep excavation, ventral projection slightly larger than dorsal projection ( Fig. 28 d, e).
