Type material: Holotype: ♀, Jamaica, Saint James Parish, Hermitage Reservoir [18°51’N, 76°46’W], 24 July 1960, P. & C. Vaurie leg. ( AMNH). GoogleMaps

Paratypes: JAMAICA: 2♀, 5 juveniles, same locality as holotype, 30 October 1957, A.M. Chickering leg. ( MCZ 69718) GoogleMaps ; 1♀, 5 juveniles, Hanover Parish, trail to Dolphin Head [18°22’N, 78°10’W], 24 June 1954, A.M. Chickering leg.

Etymology. The specific name is an adjective derived from the type locality, Jamaica.

Diagnosis. Females of N. jamaicana sp. nov. resemble those of N. lucea sp. nov. ( Fig. 96 View FIGURES 96 − 98 ) in the median septum with posterior median protrusion ( Fig. 79 View FIGURES 79 − 81 ). They are distinguished from this species by the anterior rim straight and by the posterior median protrusion rounded ( Fig. 79 View FIGURES 79 − 81 ). Males are unknown.

Description. Female (AMNH, holotype): Prosoma orange brown with thin brown lines extending posteriorly from PME, along lateral margins of the cephalic region and, concentrically, from fovea on thoracic region. Chelicerae orange brown. Legs and pedipalps orange. Leg femora and tibiae ventrally mottled with brown spots. Sternum orange with brown margins. Endites orange, distally cream colored. Labium brown, distally cream colored. Opisthosoma cream colored, densely covered with gray marks. Total length 9.9. Prosoma: 4.1 long, 3.6 wide. Opisthosoma: 5.7 long, 3.7 wide. Eyes: diameters: 0.27, 0.25, 0.15, 0.20; interdistances: 0.22, 0.15, 0.42, 0.38, 0.18, 0.09. Legs (2143): I: 12.9 (3.8, 2.0, 3.4, 2.9, 0.8); II: 13.2 (4.0, 2.1, 3.3, 3.0, 0.8); III: 10.4 (3.3, 1.8, 2.2, 2.4, 0.7); IV: 12.3 (3.7, 1.5, 2.9, 3.3, 0.9). Epigyne: epigynal field roughly rectangular, slightly longer than wide with strongly recurved anterior groove; anterior rim entire; median septum two times wider than long ( Fig. 79 View FIGURES 79 − 81 ). Vulva: glandular projections short, round with large base; spermathecae packed within large sclerotized structure with one large oblong part opening from copulatory ducts and one cylindrical part opening to fertilization ducts; internal ducts indistinguishable ( Figs 80−81 View FIGURES 79 − 81 ).

Male: unknown.

Variation. Females (n = 4): total length 8.3−10.5; prosoma length 4.1−4.7; femur I length 3.7−4.3.

Distribution. Known from northwestern Jamaica, parishes of Saint James and Hanover (Map 5).
