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 44 ) and a remarkable ess in females ( Fig. 44E View FIGURE 44 ).

Description. Male (holotype): Carapace and legs orange ( Fig. 44A View FIGURE 44 ); chelicerae, labium, endites and sternum yellowish orange; coxae lighter. Abdomen light gray, dorsal pattern with light gray chevron bands as in figure 6K, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 8.5. Carapace 4.15 long, 3.8 wide. 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 PMS. Palp with embolus shorter than palpal tibia, slightly curved, but strongly twisted ( Fig. 44B‒C View FIGURE 44 ); embolar tip with two ventral short extensions ( Fig. 45E‒F View FIGURE 45 ).

Female (paratype): Carapace pale yellow. Chelicerae, labium, coxas, legs, endites and sternum as in male. Abdomen as in male ( Fig. 44D View FIGURE 44 ). 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. Posterior unpaired claws ( Fig. 45J View FIGURE 45 ) and PLS as in male. External genital area with weakly sclerotized anterior plate, strongly sclerotized lep and remarkable ess ( Fig. 44E View FIGURE 44 ). Internal genitalia with receptaculum without invagination and uterus externus with narrow base ( Figs 44F View FIGURE 44 ; 45A‒C).

Natural history. Most of specimens were collected with arboreal funnel traps.

Distribution. Brazilian States of Amazonas and Pará ( Fig. 44G View FIGURE 44 ).
