Etymology
. The specific name is a noun in apposition taken from the county of the
type
locality.
Diagnosis
.
Novalena plata
differs from
N. prieta
in having the primary spermathecae less curved (
Fig. 34
b) and from
N. rothi
in having the atrium with lateral margins forming a small spiral that surrounds the copulatory openings (
Fig. 34
a).

.
Female
(
holotype
): Carapace light brown, white feathery scales present. Chelicerae dark brown, condyles orange. Endites and labium orange with white tips. Sternum dark brown with a central line orange. Legs orange with three rings on femur, one on patella, two on tibia, and one on metatarsus. Opisthosoma dark brown with an anterior brown spot, two longitudinal anterior yellow lines, and four posterior chevrons. Spinnerets orange, basal segment of PLS dark brown. Total length 5.88. Carapace length 2.75, width 1.88, cephalic region width 1.05, ocular region width 0.57. Eye diameter: AME 0.12, ALE and PLE 0.15, PME 0.13.
