Diagnosis. Males resemble similar congeners Nops ernestoi and Nops campeche n. sp. by having a long and prolaterally twisted embolus; but can be distinguished by its embolus with a narrower base and weakly curved (Fig. 32B‒C), ending with three extensions, one thicker than the other (Fig. 33D‒E). Females with narrow invagination on receptaculum and uterus externus with narrow base (Fig. 33G‒H).
Description. Male (holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter (Fig. 32A). Endites, labium and sternum light orange. Abdomen green grayish dorsal pattern as in figure 6I (Fig. 32A). Anal tubercle and spinnerets lighter than abdomen. Total length 8.4. Carapace 5.7 long, 4.7 wide. Leg measurements: I: 4.0; II: 3.9; III: 3.5; IV: 4.15. Posterior unpaired claws elongated and dorsally reflexed (Fig. 33K‒L). PLS longer than PMS. Palp with embolus longer than palpal tibia, with a narrow base and weakly curved (Fig. 32B‒C), ending with three extensions, one thicker than the other (Fig. 33D‒E).
Female (paratype): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male. Abdomen as in male, but somewhat darker. Anal tubercle and spinnerets lighter than abdomen. Total length 8.6. Carapace 5.8 long, 4.7 wide. Sternum 3.8 long, 3.2 wide. Leg measurements: I: 4.0; II: 3.85; III: 3.60; IV: 4.15. Posterior unpaired claws and PLS as in male.
