Figure 71G ‒LView FIGURE 71; 74A ‒F

Nops variabilis Keyserling, 1877: 218  , pl. 7, fig. 8. Male and female syntypes from New Granada (today city of Bogotá), Colombia, E. Keyserling ( 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.

Additional material examined. COLOMBIA: Bogotá: Páramo de Monserrate (4°36′21″N, 74°2′23″W)GoogleMaps  , Bogotá, 1968‒1969, H. Sturm, 1♂ 1♀ 2 immature ( AMNH)  .

VENEZUELA: Mérida: Páramo La Culata   , 18.5 km NE Mérida, (08°44′34″N, 71°03′44″W), 2950 m, 25.v.1998, R. Anderson, dead leaves under Espeletia schultzi  , 1 immature ( AMNH)GoogleMaps  .

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. 5CView FIGURE 5); but can be distinguished by having the PLS of equal size as the PMS similar to the figure 7C ‒D.

Description. Male (Bogotá, AMNH): Carapace, chelicerae and legs light orange, coxae and trochanters lighter ( Fig. 74AView FIGURE 74). 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. 5CView FIGURE 5). PLS of equal size as PMS. Palp with straight embolus, not twisted and shorter than palpal tibia ( Figs 71H ‒IView FIGURE 71; 74B ‒C); embolar tip with a small cut on prolateral side and one short extensions ( Fig. 71H ‒IView FIGURE 71).

Female (Bogotá, AMNH): Carapace, chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 74DView FIGURE 74). 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. 71LView FIGURE 71) and PLS as in male. External genital area with slightly sclerotized anterior plate, and lep, unremarkable ess ( Fig. 74EView FIGURE 74). Internal genitalia with wide invagination on receptaculum and uterus externus with narrow base ( Figs 71JView FIGURE 71; 74F).

Natural history. Specimens from AMNH were collected with Barber pitfall traps.

Distribution. Known from Venezuela and Colombia ( Fig. 57GView FIGURE 57).
