Diagnosis. Both sexes resemble the similar congener Nops minas  , which have a similar abdominal pattern as in figure 6I, and by having the PLS longer than PMSAbout PMS and the posterior unpaired claws small ( Fig. 5C View Figure ); but can be distinguished by a strongly curved embolus, longer than palpal tibia ( Fig. 59B, D View Figure ) in males, and a strongly sclerotized lep, remarkable ess and sclerotizations on lateral margins of anterior plate in external female genitalia ( Fig. 59F View Figure ).

Description. Male ( MCTPAbout MCTP 21983): Carapace, sternum, legs and labium orange. Chelicerae, endites and coxae orange yellowish.

Sternum 4.6 long, 3.6 wide. Leg measurements: I: 4.1; II: 4.05; III: 3.5; IV: 4.15. Posterior unpaired claws small, as in other three‒clawed spiders ( Fig. 62 A‒C View Figure ). PLS longer than PMSAbout PMS ( Fig. 61B View Figure ). Palp with an embolus longer than tibia, strongly curved at the first third forming a 90° angle, apical part swollen, the rest thin ( Fig. 59B‒C View Figure ; 63B‒C); tip with two ventral short extensions and a reborded dorsal margin ( Figs. 63D‒F View Figure ).

Female ( MCTPAbout MCTP 27788). Carapace, chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 59D View Figure ). Anal tubercle and spinnerets whitish yellow.
