Figure 16 a–c; Map 6

Type. Holotype female: MEXICO : Mexico City: Parque Nacional Cumbres del Ajusco , 12.III.1976, no collector data (CNAN-T0956), deposited at CNAN .

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

Diagnosis. Novalena ajusco differs from N. bipunctata , N. intermedia , and N. alvarezi in having the atrium with anterior margin and spurs strongly sclerotized ( Fig. 16 a) and from N. dentata and N. leonensis in having the spurs more projected ventrally ( Fig. 16 c).

Description. Female (holotype): Carapace brown, white feathery scales present. Chelicerae brown, condyles light brown. Endites and labium light brown with white tips. Sternum light brown. Legs light brown with three rings on femur, one on patella, two on tibia and two on metatarsus. Opisthosoma light brown with several anterior black dots and four posterior chevrons. Spinnerets yellow, basal segment of PLS with a diffuse spot black. Total length 5.63. Carapace length 2.63, width 1.63, cephalic region width 0.95, ocular region width 0.52. Eye diameter: AME 0.1, ALE and PME 0.13, PLE 0.12. Distance between eyes: AME-AME 0.04, AME-ALE 0.04, AME-PME 0.12, ALE-PLE 0.04, ALE-ALE 0.23, PME-PME 0.08, PME-PLE 0.06. Clypeus height 0.13. Chelicerae with three retromarginal teeth; basal segment length 0.97, fang length 0.42. Labium wider than long (0.36/0.27). Endites almost straight (distance at their base compared at their tips 0.36/0.18). Sternum longer than wide (1.36/1.12). Opisthosoma longer than wide (3.33/2). ALS separated by less their basal diameter (0.19/0.23), PLS with distal segment shorter than basal segment (0.37/0.56).

Number of trichobothria on tarsus: I—6, II— 6, III—5, IV—6. Dorsal spines on pedipalp femur: 2. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (0.71/0.48); atrium with anterior margin strongly sclerotized and more protruded than posterior margin; anterior sclerotized spurs adjacent ( Fig. 16 a, c).
