Figures 1 b, f, 16f–h; Map 5

Type. Holotype female: MEXICO: Michoacán: Municipality of Uruapan, Highway Uruapan-Los Reyes Salgado, 19°31′38.1″N, 102°11′31.9″W, 2300 m, 24.XI.2000, F. Álvarez, E. González, O. Delgado, J.L. Castelo, E. Lira, O. Francke, and C. Durán (CNAN-T0954), deposited at CNAN .

Etymology. The specific name is a patronym in honor of Fernando Álvarez Padilla, one of the collectors of the holotype, for his contribution to spider taxonomy in Mexico.

Diagnosis. Novalena alvarezi differs from N. intermedia in having the atrium procurved, from N. ajusco and N. leonensis in having the spurs separated by their basal width, and from N. dentata in having the atrium strongly procurved ( Fig. 16 f).

Description. Female (holotype): Carapace light brown. Chelicerae reddish, condyles orange. Endites and labium light brown with white tips. Sternum orange with brown border. Legs orange; metatarsi and tarsi dark brown. Three intense black rings on femur, one on patella, and two on tibia. Opisthosoma light brown with reddish anterior spot and five posterior chevrons. Spinnerets yellow, basal segment of PLS with a black diffuse spot. Total length 7.13. Carapace length 3.13, width 2, cephalic region width 1.19, ocular region width 0.67. Eye diameter: AME 0.1, ALE 0.17, PME and PLE 0.15. Distance between eyes: AME-AME 0.06, AME-ALE 0.06, AME-PME 0.13, ALE-PLE 0.04, ALE-ALE 0.29, PME-PME 0.06, PME-PLE 0.06. Clypeus height 0.15. Chelicerae with three to four retromarginal teeth; basal segment length 1.03, fang length 0.45. Labium slightly wider than long (0.45/ 0.36). Endites slightly convergent (distance at their base compared at their tips 0.45/0.27). Sternum longer than wide (1.57/1.19). Opisthosoma longer than wide (3.75/2.63). ALS separated by less their basal diameter (0.19/ 0.25), PLS with distal segment slightly shorter than basal segment (0.29/0.37). Leg lengths: I—femur 1.9/ patellatibia 2.28/ metatarsus 1.52/ tarsus 1.19; II—1.86/ 2.14/ 1.52/ 1.1; III—1.81/ 2.14/ 1.67/ 1.05; IV—2.33/ 2.76/ 2.48/ 1.19. Spination: femur dorsal I—1-1 -1/ II—1-2 -3/ III—1-2 -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/ 1-1-0/ 0; II—0/ 2-2-2/ 0-1-1/ 0; III—2-2 -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—5, II—5, III—5, IV—6. Dorsal spines on pedipalp femur: 3. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (0.92/0.48); atrium superficial and procurved with anterior margin not sclerotized; anterior sclerotized spurs separated by their basal width ( Fig. 16 f, h). Internal genitalia: copulatory ducts straight, primary spermathecae adjacent with dorsal transverse mark ( Fig. 16 g).

Male. Unknown.

Variation. Body length 6.75–7.13; carapace length 3.13–3.25; patella-tibia I length 2.38–2.43 (n = 2).

Additional material examined. Paratype: MEXICO : Michoacán: same data as holotype, 1 ♀ (CNAN- T0955).

Distribution. MEXICO: Michoacán (Map 5).
