Etymology. The specific name is a noun in apposition, derived from the type locality.

Diagnosis. Both sexes resemble the similar congener N. bahia n. sp. by having the posterior unpaired claws elongated and dorsally reflexed ( Fig. 5B ) and the PLS longer than PMS; but can be distinguished by lacking the chevron lines at distal dorsal part of abdomen, males with embolus longer and slightly curved ( Fig. 53B‒D ) and females with narrow invagination and strongly sclerotized distal margin of lobes ( Fig. 53G ).

Description. Male (holotype): Carapace and legs orange ( Fig. 53A ); chelicerae, labium, endites and sternum yellowish orange; coxae lighter. Abdomen light gray, dorsal pattern with two light gray irregular spots on the first dorsal anterior third of the abdomen and a median thin light gray line similar as in Fig. 6I , lighter ventrally. Anal tubercle and spinnerets light gray. Total length 8.9. Carapace 5.15 long, 3.7 wide. Sternum 4.2 long, 3.9 wide. Leg measurements: I: 4.0; II: 3.8; III: 3.5; IV: 4.15. Posterior unpaired claws elongated and dorsally reflexed. PLS longer than PMS. Palp with embolus longer than palpal tibia, curved to prolateral side ( Figs 53B‒D ; 54G); wide embolar tip, with five long extensions: two ventral and three dorsal, and a row of small spicules on the ventral margin ( Fig. 54I ‒L ).

Female (paratype): Carapace, chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 53E ). Anal tubercle and spinnerets whitish yellow. Total length 9.5. Carapace 5.4 long, 4.0 wide. Sternum 4.9 long, 4.0 wide. Leg measurements: I: 4.1; II: 4.0; III: 3.7; IV: 4.15. Posterior unpaired claws ( Fig. 54A ), and PLS as in male. External genital area with strongly sclerotized anterior plate and lep, remarkable ess ( Fig. 53F ). Internal genitalia with narrow invagination on receptaculum and strongly sclerotized distal margin of lobes, uterus externus with narrow base ( Figs 53G ; 54D‒F).

Distribution. Known from the Brazilian State of Bahia ( Fig. 55A ).
