Males resemble similar congeners  Nops guanabacaoeand  Nops largusby having a long embolus; but can be distinguished by having the embolus slightly twisted ( Figs 16G; 17B‒C) and the tip ending in five small extensions, three tiny on dorsal part and two greater on ventral part ( Fig. 16H‒I). Females can be distinguished by a receptaculum with wider and less sinuous invagination ( Fig. 16J‒L).   Description. Male( holotype): Carapace dark orange. Chelicerae, palps and legs orange; coxae and trochanters lighter. Endites, labium and sternum light orange.

Leg measurements: I: 3.75; II: 3.65; III: 3.0; IV: 3.9. Posterior unpaired claw elongated and dorsally reflexed. PLS longer than PMS. Palp with embolus longer than palpal tibia, slightly twisted ( Figs 16G; 17B‒C); tip ending in five short extensions, three tiny on dorsal part and two greater on ventral part ( Fig. 16H‒I).  Female(AMNH): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male. Abdomen as in male, but somewhat lighter. Anal tubercle and spinnerets lighter than abdomen. Total length 8.25. Carapace 5.35 long, 3.1 wide. Sternum 3.6 long, 2.9 wide.
