Figure 34 a–c; Map 1

Type. Holotype female: USA: Colorado: La Plata Co. , Durango , Ojo de los Encinos , 37°18′55.29″N, 107°52′08.84″W, 2003 m, 4–5.VI.1947, G.M. Bradt, deposited at AMNH .

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

Diagnosis. Novalena plata differs from N. prieta in having the primary spermathecae less curved ( Fig. 34 b) and from N. rothi in having the atrium with lateral margins forming a small spiral that surrounds the copulatory openings ( Fig. 34 a).

Description. Female (holotype): Carapace light brown, white feathery scales present. Chelicerae dark brown, condyles orange. Endites and labium orange with white tips. Sternum dark brown with a central line orange. Legs orange with three rings on femur, one on patella, two on tibia, and one on metatarsus. Opisthosoma dark brown with an anterior brown spot, two longitudinal anterior yellow lines, and four posterior chevrons. Spinnerets orange, basal segment of PLS dark brown. Total length 5.88. Carapace length 2.75, width 1.88, cephalic region width 1.05, ocular region width 0.57. Eye diameter: AME 0.12, ALE and PLE 0.15, PME 0.13. Distance between eyes: AME- AME 0.04, AME-ALE 0.02, AME-PME 0.12, ALE-PLE 0.02, ALE-ALE 0.23, PME-PME 0.06, PME-PLE 0.04. Clypeus height 0.13. Chelicerae with three retromarginal teeth; basal segment length 0.97, fang length 0.42. Labium wider than long (0.45/0.33). Endites almost straight (distance at their base compared at their tips 0.45/ 0.27). Sternum longer than wide (1.43/1.19). Opisthosoma longer than wide (3.24/1.19). ALS separated by less their basal diameter (0.15/0.29), PLS with distal segment as long as basal segment (0.38/0.38). Leg lengths: Ifemur 2.05/ patella-tibia 2.38/ metatarsus 1.67/ tarsus 1.14; II—1.9/ 2.24/ 1.62/ 0.9; III—1.86/ 2.19/ 1.86/ 1.05; IV—2.57/ 3.1/ 2.7/ 1.33. Spination: femur dorsal I—1-1 -2/ II—1-1 -2/ III—1-1 -2/ IV—1-1 -2; 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/ 1-1-2/ 1-1-0/ 1-1-0; IV—1-1 -0/ 1-1-2/ 1-1-0/ 1-1-0; metatarsus I—0/ 2-2-2/ 0-1-1/ 0; II—0-0-1/ 2-2-2/ 0-1-1/ 0; III—3-1 -2/ 2-2-2/ 0-1-1/ 0-1-1; IV—3-1 -2/ 1-2-2-2/ 0- 1-1/ 0-1-1. Number of trichobothria on tarsus: I—5, II—5, III—5, IV—5. Dorsal spines on pedipalp femur: 2. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (0.9/0.52); atrium in shallow depression with lateral margins forming a small spiral that surrounds the copulatory openings; anterior spurs slightly sclerotized separated by twice their basal width ( Fig. 34 a, c). Internal genitalia: copulatory ducts straight, primary spermathecae separated by less their width ( Fig. 34 b).

Male. Unknown.

Distribution. USA: Colorado (Map 1).
