Figures 11–14

Types. Male holotype (IBSP 89347) from Rio Yuyapichis, Panguana Biological Station (09’37’S 74°56’W), Huanuco, Peru, 25.x–26.xi.1983, M. Verhaagh. Three males paratypes IBSP (89352, 89349 and 89348), same data as holotype

Additional material examined. PERU: Same data as holotype, 1♂ ( IBSP 249864 for SEM) .

Etymology. The specific name is a patronymic honoring Enrique Sanchez Rodriguez, the first author’s father.

Diagnosis. Males of N. enriquei n. sp. resembles those of N. armandoi n. sp. by the large tegulum reaching or exceeding the palpal tibia length but are readily recognized by having an elongated palpal tibia, two times the patella length ( Fig. 11 B–C), and by the embolus projecting from the prolateral distal surface of the tegulum ( Fig. 14A ), with the keel bordering the tip and very short projections ( Fig. 14 D–F).

Description. Male (holotype): Total length 7.2. Carapace 4.0 long, 3.3 wide. Sternum 3.4 long, 3.0 wide. Leg measurements: I: 3.85; II: 3.8; III: 3.4; IV: 4.1. Carapace orange-brown with weakly dorsal pattern ( Fig. 11E ). Chelicerae, palps, sternum orangish brown, endites, labium pale brown ( Fig. 11F ), and legs orange-brown ( Fig. 11D ); coxae and trochanters lighter. Abdomen pale gray, dorsal pattern unnoticeable ( Fig. 11A ). Anal tubercle and spinnerets lighter than abdomen. Palp with a globose oval tegulum ( Fig. 11 B–C) and an embolus with the keel bordering the tip and very short projections ( Fig. 14 D–F).

Female: unknown.

Distribution. Known only from type locality in Peru ( Fig. 18G ).
