Type. Holotype female: MEXICO: Michoacán: Municipality of Zitácuaro, Zitácuaro, 19°21′N, 100°28′W, 27.VI.1936, L.I. Davis, deposited at AMNH (examined).
Diagnosis. The males of N. annamae differ from all other species by a membranous fulcrum near the base of the embolus (Fig. 2 a) (absent in all other species). The females are similar to N. mexiquensis in having the atrium with lateral sclerotized tips (Fig. 2 c), but differ from that species in having the atrial spurs separated from posterior margin by three times their length (Fig. 2 c).
Description. Male (allotype): Carapace light brown. Chelicerae brown, condyles light brown. Endites and labium light brown with white tips. Sternum with two longitudinal black bands. Legs light brown with three rings on femur. Opisthosoma light brown with an anterior dark brown spot, two lateral bands, and three posterior chevrons. Spinnerets with ALS light brown, PLS with dark brown basal part and light brown distal part. Total length 7.5. Carapace length 3.8, width 2.4, cephalic region width 1.3, ocular region width 0.8. Chelicerae with three retromarginal teeth; basal segment length 1.4, fang length 0.7. Labium wider than long (0.5/0.4). Endites slightly convergent (distance at their base compared at their tips 0.5/0.3). Sternum longer than wide (1.8/1.43). Opisthosoma longer than wide (4/2). ALS separated by their basal diameter (0.3/0.3), PLS with distal segment slightly longer than basal segment (0.5/0.4). Leg lengths: I—femur 3.2/ patella-tibia 4.05/ metatarsus 3.2/ tarsus 2.3; II—2.8/ 3.6/ 3/ 2; III—2.6/ 3.4/ 3.2/ 1.8; IV—3.8/ 5.72/ 4.85/ 2.55. 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 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/ 0-1-1; II—0-0-2/ 2-2-2/ 0-1-1/ 0-1-1; III—1-1 - 2/ 2-2-2/ 1-1-1/ 1-1-1; IV—1-2 -2/ 2-1-2-2/ 1-1-1/ 1-1-1. Number of trichobothria: I—6, II—6, III—6, IV—6. Number of dorsal spines on pedipalp: femur 3, tibia?. Cymbium length 1.2, width 0.8. Embolus curved; conductor with ventral projection slightly larger than dorsal projection; tegular median process with one rounded projection; fulcrum present; dorsal projection of RTA with two subprocesses, ventral projection slightly flattened (Fig. 2 a, b).
Female (holotype): Coloration similar to male, slightly darker. Total length 9.6. Carapace length 4.45, width 2.8, cephalic region width 1.6, ocular region width 1. Chelicerae with three retromarginal teeth; basal segment length 1.9. Labium wider than long (0.63/0.5). Endites convergent (distance at their base compared at their tips 0.63/0.3). Sternum longer than wide (2.1/1.65). Opisthosoma longer than wide (5.4/3.15). ALS separated by more their basal diameter (0.4/0.3), PLS with distal segment slightly longer than basal segment (0.6/0.5). Leg lengths: I—femur 3.25/ patella-tibia 4.3/ metatarsus 3/ tarsus 2.05; II—3.1/ 3.7/ 2.8/ 1.8; III—3.1/ 3.6/ 2.9/ 1.7; IV—4.1/ 1.5/ 3.45/ 2.25.

Number of trichobothria on tarsus: I—8, II—8, III—8, IV—8. Dorsal spines on pedipalp femur: 3. Epigynal plate wider than long (1/0.7); atrium in shallow depression, anterior margin with two sclerotized tips; anterior hyaline spurs separated by more their basal width (Fig. 2 c, e).
