Diagnosis. Males of N. anama sp. nov. resemble those of N. niveomaculata comb. nov. by the palp with a C-shaped tegular groove ( Figs. 28 , 34 , 50 , 56 ) (longitudinal in N. gaturama sp. nov., see Fig. 39 ). They are distinguished from this species by tegulum indented retrolaterally at the groove leaving the subtegulum visible in ventral view and by the embolus arising from tegulum at 2 o’clock position ( Figs. 28 , 34 ) (6 o’clock in N. gaturama sp. nov., 3 o’clock in N. niveomaculata comb. nov., see Figs. 39 , 50 ). Females are distinguished from those of the remaining species of the genus by the epigyne with median septum oval, widest in the median section ( Figs. 30 , 36 ) (oblong in N. gaturama sp. nov., subtriangular in N. niveomaculata comb. nov., see Figs. 41 , 52 ).

Description. Male (IBSP 134951). Prosoma brown; fovea dark brown; eye borders black. Chelicerae brown with three longitudinal black stripes. Legs and palps brown, tarsi and metatarsi darker. Labium and endites brown, distally translucent white. Sternum brown with darker margins. Opisthosoma cream colored; dorsally with faded, indistinct pale brown pattern (Fig. 1). Total length 12.6. Prosoma: 5.6 long, 4.8 wide. Opisthosoma: 6.6 long, 4.3 wide. Eyes: diameters: 0.38, 0.32, 0.21, 0.33 interdistances: 0.26, 0.11, 0.36, 0.35, 0.23, 0.15. Legs : I: 29.9 (8.0, 2.9, 8.5, 8.4, 2.1); II: 32.1 (8.9, 3.0, 9.3, 8.9, 2.0); III: 20.4 (6.2, 2.1, 5.6, 5.0, 1.5); IV: 23.9 (7.2, 2.2, 6.2, 6.4, 1.9). Palp : RTA acuminate, with long slightly curved tip in ventral view, triangular with a wide base in retrolateral view ( Figs. 27-29 , 33-35 ).

Female (IBSP 7599). Coloration pattern as in male, slightly lighter and with opisthosoma with dorsal pattern of brown irregular marks laterally and median triangular marks down posterior half ( Fig. 2 ). Total length 14.6. Prosoma : 6.5 long, 6.1 wide. Opisthosoma: 8.1 long, 5.0 wide. Eyes : diameters: 0.45, 0.39, 0.34, 0.38 interdistances: 0.45, 0.34, 0.62, 0.78, 0.40, 0.40. Legs : I: 28.1 (8.1, 3.1, 7.5, 7.7, 1.7); II: 28.6 (8.2, 3.6, 7.3, 7.7, 1.8); III: 20.0 (6.2, 2.6, 5.1, 4.7, 1.4); IV: 23.2 (7.0, 2.6, 5.8, 6.0, 1.8). Epigyne: epigynal plate as wide as long; median septum one and a half times longer than wide; hood-like projection triangular, slightly wider than long ( Figs. 30 , 36 ). Vulva: glandular projection anterio-laterad, one and a half times longer than wide ( Figs. 31-32 , 37 ).

Variation. Males (n = 9): total length: 11.0-15.9; prosoma length: 4.9-7.2; femur I length: 8.0-10.1. Females (n = 2): total length: 13.1-14.6; prosoma length: 6.1-6.5; femur I length:8.2-8.5.

Distribution. Known from northeastern and southeastern Brazil ( States of Alagoas, Sergipe, Bahia and Espírito Santo) ( Fig.60 ).

Etymology. The specific name is a noun from the Tupi Indian language meaning “thick, wide” and refers to more robust and larger size of the spiders of this new species.
