Diagnosis. Both sexes resemble the similar congener Nops campeche  n. sp. by having the most common abdominal pattern ( Fig. 6I View Figure ), 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 PMSAbout PMS. Males have the embolus thicker in the middle part ( Figs 37C‒E View Figure ; 40C), ending in three long extensions ( Fig. 40D‒E View Figure ).

Description. Male (holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter ( Fig. 37A View Figure ). Endites, labium and sternum orange ( Fig. 37B View Figure ). Abdomen green grayish dorsally with the most common pattern as in figure 6I ( Fig. 37A View Figure ). 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 View Figure ). PLS longer than PMSAbout PMS. Palp with a prolaterally curved embolus, longer than palpal tibia ( Fig. 37C‒E View Figure ); tip ending in three long extensions ( Fig. 40D‒E View Figure ).

Female ( MCZAbout MCZ 128560): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male. Abdomen as in male, but somewhat lighter ( Fig. 37F View Figure ). 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 View Figure ). Females with wide invagination on receptaculum and uterus externus with narrow base ( Figs 37K View Figure ; 40A‒B).

Variation. Immatures with poorly defined dorsal pattern on abdomen.

Natural history. Chickering (1967) found this species especially abundant on Barro Colorado Island, Panama together 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 View Figure ).
