Figs 96−98 , Map 5

Type material: Holotype: ♀, Jamaica, Hanover Parish, Lucea [18°26’N, 78°10’W], 21 July 1960, P. & C. Vaurie leg. ( AMNH).

Etymology. The specific name is a noun and refers to the type locality.

Diagnosis. Females of N. lucea sp. nov. resemble those of N. jamaicana sp. nov. ( Fig. 79 ), in the median septum with posterior median protrusion ( Fig. 96 ). They are distinguished from this species by the anterior rim recurved, median septum with anterior margin V-shaped and by the median protrusion triangular ( Fig. 96 ).

Description. Female: Prosoma orange brown with thin brown lines extending posteriorly from PME, along lateral margins of cephalic region and, concentrically from fovea, on thoracic region. Chelicerae orange brown with pair of thin brown longitudinal stripes. Legs and pedipalps orange. Sternum orange with brown margins. Endites orange, distally cream colored. Labium brown, distally cream colored. Opisthosoma cream colored; dorsally with dense brown pattern of irregular marks laterally and on anterior half and chevron-like marks on posterior half; ventrally mottled with brown spots. Total length 10.0. Prosoma: 4.1 long, 3.3 wide. Opisthosoma: 5.7 long, 3.5 wide. Eyes: diameters: 0.24, 0.20, 0.15, 0.20; interdistances: 0.24, 0.16, 0.42, 0.37, 0.19, 0.13. Legs: I: 11.8 (3.5, 1.9, 2.9, 2.8, 0.7): II: absent; III: 9.7 (3.1, 1.6, 2.1, 2.3, 0.6); IV: 11.9 (3.5, 1.5, 2.7, 3.4, 0.8). Epigyne: epigynal field slightly longer than wide; anterior rim entire; median septum wider than long ( Fig. 96 ). Vulva: glandular projections short, rounded with wide base; spermathecae packed within a sclerotized structure with one globose part opening from copulatory ducts and one cylindrical part opening into fertilization ducts; internal ducts indistinguishable ( Figs 97−98 ).

Male: unknown.

Distribution. Only known from the type locality (Map 5).

Remarks. See remarks for N. guanaboa sp. nov.
