Both sexes resemble the similar congener  Nops campeche  n. sp.by having the most common abdominal pattern ( Fig. 6I), and the posterior unpaired claws elongated and dorsally reflexed; but can be distinguished by lacking the abdominal pattern with a longitudinal, whitish gray line between the two irregular spots reaching the pedicel, and the PLS longer than PMS. Males have the embolus thicker in the middle part ( Figs 37C‒E; 40C), ending in three long extensions ( Fig. 40D‒E).   Description. Male( holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter ( Fig. 37A). Endites, labium and sternum orange ( Fig. 37B). Abdomen green grayish dorsally with the most common pattern as in figure 6I( Fig. 37A). Anal tubercle and spinnerets lighter than abdomen. Total length 8.0. Carapace 5.5 long, 3.0 wide. Sternum 3.6 long, 3.2 wide. Leg measurements: I: 3.9; II: 3.7; III: 3.3; IV: 4.05. Posterior unpaired claws elongated and dorsally reflexed ( Fig. 39I). PLS longer than PMS. Palp with a prolaterally curved embolus, longer than palpal tibia ( Fig. 37C‒E); tip ending in three long extensions ( Fig. 40D‒E).  Female(MCZ 128560): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male. Abdomen as in male, but somewhat lighter ( Fig. 37F). Anal tubercle and spinnerets lighter than abdomen. Total length 8.5. Carapace 5.75 long, 3.2 wide. Sternum 3.8 long, 3.5 wide. Leg measurements: I: 4.2; II: 4.0; III: 3.6; IV: 4.5. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate, strongly sclerotized lep and remarkable ess ( Fig. 37J, L). Females with wide invagination on receptaculum and uterus externus with narrow base ( Figs 37K; 40A‒B).  Variation. Immatures with poorly defined dorsal pattern on abdomen.  Natural history. Chickering (1967)found this species especially abundant on Barro Colorado Island,  Panamatogether with  Nops ursumus. Immature specimens collected by B.L. Thorne from Frijoles, Canal Zone were associated with termite nests.   Distribution. Known only from  Panama( Fig. 36B). 1848261493 1958-01-21 MCZ A. M.
