Etymology. The specific name is a Portuguese noun in apposition, derived from the region where the species occurs: Amazon River.

Diagnosis. Both sexes resemble similar congener Nops maculatus  by having the abdominal pattern with an irregular longitudinal dark gray stripe throughout the dorsum similar as in figure 6J, and the PLS two times longer than PMS; but can be distinguished by having an embolus prolaterally sinuous in males ( Fig. 46B ‒DView FIGURE 46) and females with receptaculum without invagination ( Figs 46GView FIGURE 46; 47A).

Description. Male (holotype): Carapace orange ( Fig. 46AView FIGURE 46); chelicerae, legs, coxae, labium, endites and sternum yellowish orange. Abdomen light gray, dorsal pattern with an irregular longitudinal dark gray stripe throughout the dorsum as in figure 6J, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 8.8. Carapace 5.15 long, 3.8 wide. Sternum 4.7 long, 3.2 wide. Leg measurements: I: 4.0; II: 3.75; III: 3.4; IV: 4.05. Posterior unpaired claws small, as in other three ‒clawed spiders. PLS longer than PMS. Palp with embolus longer than palpal tibia, sinuous and curved ( Fig. 46B ‒DView FIGURE 46); embolar tip beveled with short two extensions ( Fig. 47F ‒GView FIGURE 47).

Female (paratype): Carapace chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 46EView FIGURE 46). Anal tubercle and spinnerets whitish yellow. Total length 9.0. Carapace 5.3 long, 4.0 wide. Sternum 4.95 long, 3.5 wide. Leg measurements: I: 4.25; II: 4.0; III: 3.7; IV: 4.35. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate and lep, unremarkable ess ( Fig. 46FView FIGURE 46). Internal genitalia with receptaculum without invagination and uterus externus with narrow base ( Figs 46GView FIGURE 46; 47A ‒C).
