Etymology. The specific name is a colloquial term for a native of Costa Rica, and is masculine in gender.

Diagnosis. Both sexes resemble similar congeners Nops campeche n. sp. and Nops largus by having a similar dorsal abdominal pattern; but can be distinguished by having short unpaired claws on posterior legs. Males with a strongly curved and retrolaterally twisted embolus ( Fig. 40J‒L ) and females with wide invagination on receptaculum ( Figs 40G‒I ; 41F).

Description. Male (holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter ( Fig. 41A ). Endites, labium and sternum light orange. Abdomen green grayish with the most common pattern as in figure 6I. Anal tubercle and spinnerets lighter than abdomen. Total length 7.6. Carapace 4.6 long, 3.0 wide. Sternum 2.9 long, 2.6 wide. Leg measurements: I: 3.6; II: 3.5; III: 3.0; IV: 3.8. Posterior unpaired claws short but reflexed anteriorly ( Fig. 40F ). PLS longer than PMS. Palp with embolus shorter than palpal tibia, strongly curved and retrolaterally twisted ( Fig. 40J‒L ).

Female (paratype): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male. Abdomen as in male, but somewhat darker ( Fig. 41D ). Anal tubercle and spinnerets lighter than abdomen. Total length 7.9. Carapace 4.8 long, 3.2 wide. Sternum 3.0 long, 2.8 wide. Leg measurements: I: 3.8; II: 3.7; III: 3.3; IV: 4.0. Posterior unpaired claws and PLS as in male. External genital area with strongly sclerotized anterior plate, strongly

sclerotized lep and remarkable ess ( Fig. 41E ). Internal genitalia with wide invagination on receptaculum and uterus externus with narrow base ( Figs 40G‒I ; 41F).

Distribution. Costa Rica and West of Panama ( Fig. 41G ).
