Diagnosis. Males resemble similar congeners Nops pallidus  n. sp. and Nops gertschi  by having a short and thick embolus, strongly curved; but can be distinguished by the longer embolus with a shorter sclerotized margin ( Fig. 31B‒C View Figure ). Females can be distinguished by receptaculum with narrow invagination and uterus externus with narrow base ( Fig. 30G‒H, J‒L View Figure ).

Description. Male (holotype): Carapace, chelicerae, labium, endites, sternum and legs yellow ( Fig. 31A View Figure ), coxae and trochanters lighter. Abdomen pale gray, without noticeable dorsal pattern on abdomen, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 9.3. Carapace 6.4 long, 4.3 wide. Sternum 3.9 long, 3.6 wide. Leg measurements: I: 4.4; II: 4.15; III: 3.8; IV: 4.5. Posterior unpaired claws short, as in other three‒clawed spiders. PLS longer than PMSAbout PMS. Femur I‒II slight elongated. Palp with embolus distinctly shorter than tibia, thick and strongly curved ( Fig. 31B‒C View Figure ); beveled tip with a wide sclerotized margin and two short extensions ( Fig. 30B‒C View Figure ).

Female ( BSCAbout BSC 550): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male ( Fig. 31D View Figure ). Abdomen as in male. Anal tubercle and spinnerets as in male. Total length 9.7. Carapace 6.8 long, 4.5wide. Sternum 4.3 long, 3.9 wide. Leg measurements: I: 4.6; II: 4.35; III: 3.70; IV: 4.8. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate and lep, unremarkable ess ( Fig. 31E View Figure ). Internal genitalia with narrow invagination on receptaculum and uterus externus with narrow base ( Figs 30G‒H, J‒L View Figure ; 31F).

Variation. Specimens from eastern Cuba populations differ slightly in coloration from those of the western region. Specimens from Santiago de Cuba (eastern) have accentuated overall coloration, being slightly darker and have slight differences in embolus shape compared with males from west of Cuba.

Natural history. All specimens from Santiago de Cuba were collected under stones in xerophytic coastal scrub. Specimens from Guantánamo were collected under dead plants of Agave  sp. in secondary scrub.

Distribution. Known from a few localities in Cuba ( Fig. 31G View Figure ).
