Figure 20 a–c; Map 5

Type. Holotype female: MEXICO: Oaxaca : Municipality of Santiago Comaltepec , El Mirador Santiago Comaltepec , 17°34′42.12″N, 96°30′23.88″W, 2952 m, 16. VI.2007, A. Valdez and C. Santibáñez (CNAN-T0965), deposited at CNAN .

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

Diagnosis. Novalena comaltepec differs from N. perote in having the atrium strongly procurved, from N. valdezi in having the atrium four times wider than long ( Fig. 20 a), and from N. punta in having the atrium with two sclerotized tips on posterior margin ( Fig. 20 c).

Description. Female (holotype): Carapace yellow. Chelicerae dark brown, condyles light brown. Endites and labium dark brown with white tip. Sternum dark brown with a central orange spot. Coxa yellow with a black spot. Legs light brown, metatarsus and tarsus dark brown. Three strongly marked rings on femur, one patella, and two on tibia. Opisthosoma dark brown with anterior reddish spot, posterior light brown foliage, and four pairs of lateral white groups of hairs. Spinnerets dark brown, PLS with distal segments light brown. Total length 10. Carapace length 4.38, width 2.75, cephalic region width 1.82, ocular region width 0.73. Eye diameter: AME and PLE 0.21, ALE 0.23, PME 0.19. Distance between eyes: AME-AME 0.06, AME-ALE 0.08, AME-PME 0.21, ALE-PLE 0.06, ALE-ALE 0.46, PME-PME 0.12, PME-PLE 0.19. Clypeus height 0.23. Chelicerae with three retromarginal teeth; basal segment length 1.82, fang length 0.73. Labium slightly wider than long (0.64/0.61). Endites almost straight (distance at their base compared at their tips 0.64/0.36). Sternum longer than wide (2.05/1.71). Opisthosoma longer than wide (5.63/3.5). ALS separated by half their basal diameter (0.19/0.38), PLS with distal segment shorter than basal segment (0.35/0.4).

Spination: femur dorsal I—1-2 -3/ II—1-3 -3/ III—1-3 -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/ 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/ 0-0-1/ 0-0-1. Number of trichobothria on tarsus: I—6, II—6, III—6, IV—6. Dorsal spines on pedipalp femur: 3. Prolateral spines on tibia: 1-2. Epigynal plate wider than long (1.06/0.61); atrium in shallow depression and strongly procurved with sclerotized tips on posterior margin; anterior hyaline spurs separated by more their basal width ( Fig. 20 a, c). Internal genitalia: copulatory ducts curved in lateral direction, primary spermathecae curved and separated by less their width ( Fig. 20 b).

Male. Unknown.
