Etymology. The specific name is a noun and refers to one of the major indigenous ethnic groups inhabiting the Caribbean.

Diagnosis. Males of N. taino sp. nov. are distinguished from those of the other species of the genus by the palp with vRTA absent, median apophysis with strongly pointed tip, and embolus bifid, with subdistal pointed projection ( Figs 137−139 View FIGURES 136 − 142 ). Females resemble those of N. lucea sp. nov. ( Fig. 96 View FIGURES 96 − 98 ) in the anterior rim recurved and median septum pentagonal ( Fig. 140 View FIGURES 136 − 142 ). They are distinguished from this species by the anterior rim medially pointed (rounded in the other species) by the anterior margin of the median septum straight (V-shaped in the other species) and by the absence of a posterior median protrusion ( Fig. 140 View FIGURES 136 − 142 ) (present in N. lucea ).

Description. Male (NMNH, holotype): Prosoma orange, slightly darker at eye area, with thin black lines extending along and between thoracic striae. Fovea and eye borders black. Chelicerae orange. Pedipalps yellow. Legs yellow with black marks at the base of spines. Femora ventrally mottled with black spots. Sternum pale yellow with pale orange margins. Endites pale yellow, distally cream colored. Labium orange, distally pale yellow. Opisthosoma cream colored; dorsally with black pattern of irregular marks laterally and on anterior half and chevron-like marks on posterior half ( Fig. 5 View FIGURES 1 − 6 ). Total length 7.8. Prosoma: 3.9 long, 3.4 wide. Opisthosoma: 3.9 long, 2.5 wide. Eyes: diameters: 0.25, 0.22, 0.15, 0.21; interdistances: 0.17, 0.18, 0.31, 0.27, 0.14, 0.05. Legs (2143): I: 15.7 (4.2, 2.0, 4.2, 4.2, 1.1); II: 16.2 (4.5, 2.1, 4.2, 4.4, 1.0); III: 12.5 (3.8, 1.6, 2.9, 3.4, 0.8); IV: 15.6 (4.5, 1.7, 3.5, 4.8, 1.1). Palp: VTA elongate, retrolateral; dRTA conical, ventrally curved in retrolateral view; median apophysis arising from tegulum at 3 o’clock position; conductor with the same width throughout its entire length; TBC large, conical, two times longer than wide; embolus arising from tegulum at 9 o’clock position; TBE single with subdistal ventral pointed projection and dorsal groove, flanked by distal keel, to accommodate the embolus ( Figs 136−139 View FIGURES 136 − 142 ).

Female (NMNH, paratype): Coloration pattern as in male ( Fig. 6 View FIGURES 1 − 6 ). Total length 6.5. Prosoma: 3.1 long, 2.9 wide. Opisthosoma: 3.4 long, 2.1 wide. Eyes: diameters: 0.19, 0.17, 0.12, 0.19; interdistances: 0.20, 0.23, 0.34, 0.39; 0.19, 0.11. Legs (4213): I: 10.5 (3.1, 1.5, 2.8, 2.5, 0.6); II: 10.7 (3.2, 1.6, 2.7, 2.6, 0.6); III: 8.8 (2.9, 1.3, 2.0, 2.0, 0.6); IV: 10.8 (3.2, 1.3, 2.6, 3.0, 0.7). Epigyne: epigynal field roughly rectangular, longer than wide ( Fig. 139 View FIGURES 136 − 142 ). Vulva: glandular projections short rounded with wide base; spermathecae packed within oblong sclerotized structure, slightly narrower close to fertilization ducts; internal ducts with anterior and additional median twist ( Figs 141−142 View FIGURES 136 − 142 ).

Variation. Males (n = 2): total length 6.3−7.8; prosoma length 3.4−3.9; femur I length 3.7−4.2. Females (n = 7): total length 6.5−11.0; prosoma length 3.1−4.0; femur I length 2.9−3.5.

Distribution. Known from the Dominican Republic and Puerto Rico (Map 2).
