Tentabunda antiguensis (Bryant) . Fox 1937: 464.

Diagnosis. Females of N. antiguensis comb. nov. are distinguished from those of the remaining species of the genus by the median septum roughly hexagonal with anterior and posterior margin gently procurved ( Fig. 20 ) and by the spermathecae S-shaped, winding before anterior twist ( Figs 21−22 ). Males are unknown.

Description. Female: Prosoma orange brown, mottled with small brown spots. Fovea brown. Eye borders black. Chelicerae orange brown. Legs and pedipalps orange brown. Leg femora ventrally mottled with few brown spots. Sternum yellowish orange with orange margins. Endites yellowish orange, distally cream colored. Labium yellowish orange with brown base and distally cream colored. Opisthosoma gray with irregular brown marks dorsally. Total length 16.5. Prosoma: 6.5 long, 5.4 wide. Opisthosoma: 9.6 long, 6.2 wide. Eyes: diameters: 0.28, 0.24, 0.18, 0.26; interdistances: 0.30, 0.40, 0.60, 0.68, 0.32, 0.16. Legs (1243): I: 20.1 (5.8, 3.3, 5.4, 4.6, 1.0); II: 19.8 (6.0, 3.3, 4.9, 4.6, 1.0); III: 16.2 (5.2, 2.7, 3.6, 3.8, 0.9); IV: 19.1 (5.7, 2.4, 4.4, 5.3, 1.3). Epigyne: epigynal field roughly rectangular, slightly longer than wide; anterior rim continuous, recurved ( Fig. 20 ).

Male: unknown.

Distribution. Only known from the type locality (Map 4).
