Etymology. The specific name is a patronym honoring Alex Enrique Sánchez Jardines, the son of the first author.

Diagnosis. Both sexes resemble similar congeners Nops maculatus  and Nops amazonas  n. sp. by having long PLS and elongated posterior umpaired claws; but can be distinguished by having the embolus shorter than tibia length in males ( Fig. 44B‒C View Figure ) and a remarkable ess in females ( Fig. 44E View Figure ).

Sternum 3.6 long, 3.15 wide. Leg measurements: I: 3.8; II: 3.75; III: 3.45; IV: 4.0. Posterior unpaired claws elongated and dorsally reflexed. PLS longer than PMSAbout PMS. Palp with embolus shorter than palpal tibia, slightly curved, but strongly twisted ( Fig. 44B‒C View Figure ); embolar tip with two ventral short extensions ( Fig. 45E‒F View Figure ).

Female (paratype): Carapace pale yellow. Chelicerae, labium, coxas, legs, endites and sternum as in male. Abdomen as in male ( Fig. 44D View Figure ). Anal tubercle and spinnerets whitish yellow. Total length 9.1. Carapace 4.4 long, 4.1 wide. Sternum 3.95 long, 3.4 wide. Leg measurements: I: 4.0; II: 3.9; III: 3.6; IV: 4.25.
