Figure 44 d–f; Map 3

Type. Holotype female: MEXICO: Jalisco: 19.6 km NW Los Volcanes , 7.VIII.1967, R.E. Leech (CASENT 9048886), deposited at CAS .

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

Diagnosis. Novalena volcanes differs from N. clara and N. franckei in having the primary spermathecae with anterior part wider than posterior part ( Fig. 44 e), and from N. saltoensis in having the atrium with posterior margin less protruded ( Fig. 44 d).

Description. Female (holotype): Carapace light brown, cephalic region reddish with a pair of longitudinal lines behind PME. Chelicerae reddish, condyles orange. Endites and labium reddish with white tips. Sternum orange with border brown. Legs orange with two long dark brown rings on femur, one on patella, and two on tibia. Opisthosoma light brown, lateral and ventral black spots and dark brown foliage. Spinnerets orange, PLS with basal segment darker. Total length 9.38. Carapace length 4.13, width 2.5, cephalic region width 1.67, ocular region width 0.9. Eye diameter: AME 0.21, ALE 0.23, PME 0.17, PLE 0.19. Distance between eyes: AME-AME 0.08, AME-ALE 0.1, AME-PME 0.19, ALE-PLE 0.06, ALE-ALE 0.42, PME-PME 0.13, PME-PLE 0.17. Clypeus height 0.23. Chelicerae with three to four retromarginal teeth; basal segment length 1.57, fang length 0.57. Labium slightly wider than long (0.69/0.54). Endites slightly convergent (distance at their base compared at their tips 0.69/ 0.35). Sternum longer than wide (1.95/1.67). Opisthosoma longer than wide (5.5/3.25). ALS separated by less their basal diameter (0.17/0.38), PLS with distal segment slightly longer than basal segment (0.58/0.48).

Spination: femur dorsal I—1-2 -2/ II—1-3 -3/ III—1-3 -3/ IV—1-3 -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/ 0-0-1; II—0/ 2-2-2/ 0-1-1/ 0-0-1; III—2-1 -2/ 2-2-2/ 0-1-1/ 0-1-1; IV—3-2 -2/ 2-2-2/ 0-1-1/ 0-0-1. Number of trichobothria: I—7, II—7, III—7, IV—7. Dorsal spines on pedipalp femur: 3. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (1.3/0.73); atrium superficial; anterior spurs separated by more their basal width ( Fig. 44 d, f). Internal genitalia: copulatory ducts straight, primary spermathecae adjacent, wider towards anterior part ( Fig. 44 e).

Male. Unknown.

Variation. Body length 7.5–10.38; carapace length 3.25–5; patella-tibia I length 3.38–4.75 (n = 5).
