Etymology. The specific name is a patronym honoring Dr. Elizabeth Bryant.

Diagnosis. Males of N. bryantae sp. nov. resemble those of N. gunboat sp. nov. and N. maroon sp. nov. ( Figs 70 View FIGURES 68 − 71 , 115 View FIGURES 113 − 119 ) in the vRTA bifid ( Fig. 42 View FIGURES 40 − 45 ). They are distinguished from both species by the absence of a tegular protrusion (present in the other species) and by the filiform embolus (with dorsal keels in the other two species) ( Fig. 41 View FIGURES 40 − 45 ). Females are distinguished from the other species of the genus by the median septum bearing a chaliceshaped scape ( Fig. 43 View FIGURES 40 − 45 ).

Description. Male (NMNH, holotype): Prosoma pale orange with black margins, black fovea and thin black lines along lateral margins of cephalic region and extending posteriorly from PME. Eye borders black. Chelicerae pale orange with faint longitudinal black stripe. Legs pale orange, darker at tibiae and metatarsi. Pedipalps pale yellow. Sternum pale yellow with pale brown margins. Endites pale yellow. Labium pale orange, distally pale yellow. Opisthosoma cream colored; dorsally with gray pattern of irregular marks laterally and on anterior half and chevron like marks on posterior half; ventrally mottled with few gray spots. Total length 5.2. Prosoma: 2.7 long, 2.4 wide. Opisthosoma: 2.4 long, 1.9 wide. Eyes: diameters: 0.21, 0.17, 0.11, 0.14; interdistances: 0.15, 0.06, 0.28, 0.22, 0.10, 0.05. Legs (2143): I: 9.8 (2.7, 1.1, 2.8, 2.5, 0.7); II: 10.10 (3.0, 1.2, 2.7, 2.5, 0.7); III: 8.1 (2.5, 1.0, 2.0, 2.0, 0.6); IV: 9.5 (2.9, 0.9, 2.3, 2.7, 0.7). Palp: VTA small, retrolaterally displaced; dRTA triangular in ventral view, roughly rectangular in retrolateral view; vRTA with one short conical, pointed branch and the other branch squared in retrolateral view; eRTA pointed; median apophysis arising from tegulum at 3 o’clock position; conductor with the same width throughout its entire length; TBC long, cylindrical, more than three times longer than wide; embolus arising from tegulum at 6:30 o’clock position ( Figs 40−42 View FIGURES 40 − 45 ).

Female (NMNH, paratype): Coloration pattern as in male, slightly darker. Total length 6.4. Prosoma: 2.6 long, 2.5 wide. Opisthosoma: 3.8 long, 2.2 wide. Eyes: diameters: 0.16, 0.16, 0.09, 0.14; interdistances: 0.18, 0.13, 0.30, 0.26, 0.18, 0.08. Legs (2413): I: 8.7 (2.6, 1.1, 2.4, 2.0, 0.6); II: 9.0 (2.7, 1.4, 2.3, 2.0, 0.6); III: 7.3 (2.4, 1.1, 1.5, 1.7, 0.6); IV: 8.9 (2.7, 1.0, 2.0, 2.5, 0.7). Epigyne: epigynal field roughly squared, as long as wide; anterior rim entire, recurved; median septum covered by scape, posterior margin gently procurved ( Fig. 43 View FIGURES 40 − 45 ). Vulva: copulatory ducts medially bent at a 90° angle; glandular projections small and rounded; spermathecae with one anteriad loop before anterior twist, packed within an irregular shaped sclerotized structure ( Figs 44−45 View FIGURES 40 − 45 ).

Variation. Females (n = 2): total length 6.4−6.5; prosoma length 2.6−2.7.

Distribution. Only known from the type locality (Map 3).
