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

Diagnosis. Both sexes resemble the similar congener Nops largus  Edit by having the most common abdominal pattern ( Fig. 6I), and the posterior unpaired claws elongated and dorsally reflexed, but can be distinguished by having abdominal pattern with a longitudinal, whitish gray line between the two irregular spots reaching the pedicel ( Fig. 34A, E) and the PLS of the same size as PMS.

Description. Male (holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter ( Fig. 34A). Endites, labium and sternum light orange. Abdomen green grayish with the most common pattern similar as in Fig. 6I, but with a longitudinal, whitish gray line between the two irregular spots, reaching the pedicel ( Fig. 34A). Anal tubercle and spinnerets lighter than abdomen. Total length 7.6. Carapace 4.4 long, 3.2 wide. Sternum 3.7 long, 3.1 wide. Leg measurements: I: 3.4; II: 3.3; III: 3.0; IV: 3.6. Posterior unpaired claws elongated and dorsally reflexed ( Fig. 35K). PLS same size as PMS. Palp with embolus longer than the palpal tibia, slightly twisted; beveled tip with two short extensions ( Fig. 35B ‒C).

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 7.9. Carapace 4.5 long, 3.6 wide. Sternum 3.8 long, 3.3 wide. Leg measurements: I: 3.7; II: 3.6; III: 3.3; IV: 3.8. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate, sclerotized lep and unremarkable ess ( Fig. 34F). Internal genitalia with narrow invagination on receptaculum and uterus externus with narrow base ( Fig. 34G).

Distribution. Mexico, Belize and Costa Rica ( Fig. 36A).
