Novalena calavera Chamberlin & Ivie 1942: 230, figures 61–62 (♂ ♀)
Type. Holotype male: USA: California: Riverton, 38°49′N, 120°21′W, 15.VII.1934, Ivie and Rasmussen, deposited at AMNH (examined).
Diagnosis. The males of N. calavera distinguish from N. lutzi in having the RTA with longer and pointer tips on dorsal projection (Fig. 7 b) and the ventral projection less prominent (Fig. 7 a), and from N. rothi and N. alamo in having the tegular median process less conspicuous. The females differ from N. lutzi in having the median plate narrower towards the ventral margin and the copulatory openings as long as wide (Fig. 7 e), and from N. rothi in having hoods and the copulatory openings not visible in ventral view (Fig. 7 c).
Description. Male (holotype): Carapace light brown, white spot and feathery scales present. Chelicerae dark brown, condyles orange. Endites and labium brown with white tips. Sternum brown. Legs light brown, tarsus yellow. Three weak rings on femur. Opisthosoma light brown with several black spots, reddish foliage, and four lateral pairs of brown spots. Spinnerets yellow. Total length 9.35. Carapace length 4.85, width 3.33, cephalic region width 1.9, ocular region width 0.9. Chelicerae with two retromarginal teeth; basal segment length 1.7, fang length 0.9. Labium slightly wider than long (0.6/0.5). Endites slightly convergent (distance at their base compared at their tips 0.6/0.4). Sternum longer than wide (2.3/1.8). Opisthosoma longer than wide (4.7/2.7). ALS separated by their basal diameter (0.4/0.4), PLS with distal segment slightly shorter than basal segment (0.5/0.6).

Number of trichobothria on tarsus: I—7, II—7, III—7, IV—7. Number of dorsal spines on pedipalp: femur 3, tibia 3. Cymbium length 1.8, width 0.9. Embolus curved; conductor with two projections, the dorsal one larger than ventral one; tegular median process slightly sclerotized; dorsal projection of RTA with two strongly sharp tips, ventral projection short (Fig. 7 a, b).
Female (allotype): Carapace orange, two longitudinal lines behind PME. Chelicerae brown, condyles orange. Endites and labium orange with white tips. Sternum light brown with a median band that bifurcates at the posterior part. Legs orange with three wide rings on femur and two weak rings on tibia. Opisthosoma light brown and black, with brown foliage and five pairs of lateral light brown spots. Spinnerets light brown. Total length 11.4.
