Nops variabilis Keyserling, 1877: 218  , pl. 7, fig. 8. Male and female syntypes from New Granada (today city of Bogotá), Colombia, E. Keyserling ( NHMAbout NHM 1890.7.1.492, only the female in the vial; examined). Hasselt, 1887: 85, pl. 6, figs 8–9. Berland, 1913: 85, pl. 7, fig. 11.

Remarks. Male syntype was not examined and may be lost. Fortunately specimens from Paramo de Monserrate, a locality on the outskirts of the city of Bogotá (type locality) can be assigned to this species.

Diagnosis. Males and females resemble similar congener Nops quito  , which have a similar abdominal pattern as in figure 6K, and the posterior unpaired claws small ( Fig. 5C View Figure ); but can be distinguished by having the PLS of equal size as the PMSAbout PMS similar to the figure 7C‒D.

Description. Male (Bogotá, AMNHAbout AMNH): Carapace, chelicerae and legs light orange, coxae and trochanters lighter ( Fig. 74A View Figure ). Endites, labium and sternum light orange. Abdomen light gray, dorsal pattern as in figure 6K, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 8.9. Carapace 5.5 long, 3.6 wide. Sternum 4.4 long, 3.2 wide. Leg measurements: I: 3.9; II: 3.75; III: 3.5; IV: 4.0. Posterior unpaired claws small, as in other three‒clawed spiders ( Fig. 5C View Figure ). PLS of equal size as PMSAbout PMS. Palp with straight embolus, not twisted and shorter than palpal tibia ( Figs 71H‒I View Figure ; 74B‒C); embolar tip with a small cut on prolateral side and one short extensions ( Fig. 71H‒I View Figure ).

Female (Bogotá, AMNHAbout AMNH): Carapace, chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 74D View Figure ). Anal tubercle and spinnerets whitish yellow. Total length 9.5. Carapace 5.9 long, 4.2 wide. Sternum 4.95 long, 3.8 wide. Leg measurements: I: 4.2; II: 4.1; III: 3.7; IV: 4.35. Posterior unpaired claws ( Fig. 71L View Figure ) and PLS as in male. External genital area with slightly sclerotized anterior plate, and lep, unremarkable ess ( Fig. 74E View Figure ).
