Type. Holotype female: MEXICO: Guerrero: Omiltemi, H.H. Smith, deposited at BMNH (examined).

Diagnosis. Novalena attenuata is similar to N. gibarrai and N. oaxaca , but differ from N. gibarrai in having the copulatory ducts curved in lateral direction ( Fig. 5 b) and from N. oaxaca in having the posterior margin protruded ( Fig. 5 a).

Description. Female (holotype): Carapace dark brown, longitudinal bands inconspicuous. Chelicerae and condyles dark brown. Endites brown with white tips. Labium dark brown with white tip. Sternum brown. Legs orange, metatarsus brown. Three diffuse rings on femur. Opisthosoma light brown with four posterior chevrons. ALS light brown, PLS yellow. Total length 7. Carapace length 3.25, width 2.13, cephalic region width 1.36, ocular region width 0.79. Eye diameter: AME 0.12, ALE 0.15, PME 0.17, PLE 0.19. Distance between eyes: AME-AME 0.08, AME-ALE 0.08, AME-PME 0.19, ALE-PLE 0.06, ALE-ALE 0.3, PME-PME 0.12, PME-PLE 0.1. Clypeus height 0.15. Chelicerae with four retromarginal teeth; basal segment length 1.24, fang length 0.64. Labium wider than long (0.48/0.39). Endites slightly convergent (distance at their base compared at their tips 0.48/0.33). Sternum longer than wide (1.62/1.33). Opisthosoma longer than wide (4.38/2.63). ALS separated by less their basal diameter (0.18/0.27), PLS with distal segment shorter than basal segment (0.18/0.39). Leg lengths: I—femur 2.08/ patella-tibia 2.23/ metatarsus 1.15/ tarsus 0.77; II—2 / 2.31/ 1.54/ 1.08; III—1.85/ 2.15/ 1.77/ 1; IV—2.46/ 3/ 2.54/ 1.31. Spination: femur dorsal I—1-1 -3/ II—1-3 -3/ III—1-3 -3/ IV—1-1 -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/ 1-1-2/ 1-1-0/ 0; III—1-1 -0/ 1-2-2/ 1-1-0/ 1-1-0; IV—1-1 -0/ 1-2-2/ 1-1-0/ 1-1-0; metatarsus I— 0/ 2-2-2/ 0/ 1; II—0/ 2-2-2/ 0-1-1/ 0-1-1; III—2-2 -2/ 2-2-2/ 0-1-1/ 0-1-1; IV—3-1 -2/ 1-1-1-1-2/ 0-1-1/ 0-0-1. Number of trichobothria on tarsus: I—?, II—5, III—5, IV—5. Dorsal spines on pedipalp femur: 3. Prolateral spines on pedipalp tibia: 1-2. Epigynal plate wider than long (1/0.58); atrium in shallow depression; anterior hyaline spurs, separated by more their basal width ( Fig. 5 a, c). Internal genitalia: copulatory ducts curved in lateral direction, spermathecae adjacent ( Fig. 5 b).

Male. Unknown.

Distribution. MEXICO: Guerrero (Map 8); GUATEMALA (F.O. Pickard-Cambridge 1902; unknown locality).
