Figs 46−48 , Map 2 Type material: Holotype : ♀ , Dominican Republic , Cachote , Parque Nacional de Baoruco [ 18°28’N , 71°36’W ], 7 July 2012 , Team CarBio leg. ( NMNH ). Paratypes : 1♀ , from the same vial as holotype ( NMNH ); 1♀ , same data as holotype ( NMNH ). Etymology. The specific name is a noun and refers to the type locality. Diagnosis. Females of N. cachote sp. nov. are distinguished from those of the other species of the genus by the median septum with lateral margins medially compressed and posterior margin rounded, projecting posteriorly ( Fig. 46 ) and by the spermathecae with long anteriad loop followed by strongly sinuous ducts, packed within a roughly oblong sclerotized structure ( Figs 47−48 ). Males are unknown. Description. Female (NMNH, holotype ): Prosoma yellow with brown margins, slightly darker at eye area, with brown lines extending posteriorly along lateral margins of cephalic region and from PME and concentrically from fovea on thoracic region. Fovea brown with large triangular mark anteriorly. Eye borders black. Chelicerae orange. Legs and pedipalps yellow. Leg femora and tibiae ventrally mottled with brown spots. Sternum yellow with orange margins. Endites orange, distally pale yellow. Labium brown, distally pale orange. Opisthosoma gray; dorsally covered with scattered brown marks on anterior half and completely covered on posterior half; ventrally mottled with brown spots. Total length 9.9. Prosoma: 3.9 long, 3.6 wide. Opisthosoma: 6.0 long, 4.0 wide. Eyes: diameters: 0.27, 0.23, 0.17, 0.22; interdistances: 0.25, 0.12, 0.45, 0.36, 0.19, 0.11. Legs (2143): I: 12.9 (3.8, 1.9, 3.4, 3.0, 0.8); II: 13.1 (4.0, 2.0, 3.3, 3.0, 0.8); III: 10.6 (3.3, 1.5, 2.5, 2.6, 0.7); IV: 12.4 (3.8, 1.5, 2.8, 3.4, 0.9). Epigyne: epigynal field roughly rectangular, slightly longer than wide; anterior rim divided, C-shaped on each side; median septum with anterior procurved groove ( Fig. 46 ). Vulva: copulatory ducts gently curved; glandular projections large, slightly longer than wide ( Figs 47−48 ).
