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 View Figure ), ending with three extensions, one thicker than the other ( Fig. 33D‒E View Figure ). Females with narrow invagination on receptaculum and uterus externus with narrow base ( Fig. 33G‒H View Figure ).

Description. Male (holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter ( Fig. 32A View Figure ). Endites, labium and sternum light orange. Abdomen green grayish dorsal pattern as in figure 6I ( Fig. 32A View Figure ). 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 View Figure ). PLS longer than PMSAbout PMS. Palp with embolus longer than palpal tibia, with a narrow base and weakly curved ( Fig. 32B‒C View Figure ), ending with three extensions, one thicker than the other ( Fig. 33D‒E View Figure ).

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. External genital area with weakly sclerotized anterior plate and lep, unremarkable ess ( Fig. 32E View Figure ). Internal genitalia with narrow invagination on receptaculum and uterus externus with narrow base ( Figs 32F View Figure ; 33G‒H).
