Remarks. Subsequent visits to the type locality provided no additional material. The area where the types were collected is currently under intense deforestation.

Diagnosis. Males resemble similar congeners Nops toballus  and N campeche  n. sp. by having a long and prolaterally twisted embolus; but can be distinguished by its embolus with a wider base, strongly curved at middle, and strongly twisted on the distal two thirds ( Fig. 14B‒CView FIGURE 14), ending with three short extensions on tip ( Fig. 13K‒LView FIGURE 13). Females with wide invagination on receptaculum and uterus externus with narrow base ( Fig. 14FView FIGURE 14).

Description. Male (holotype): Carapace dark orange. Chelicerae, palps, endites, labium, sternum and legs orange; coxae and trochanters lighter. Abdomen dark gray, dorsal pattern as in figure 6I. Anal tubercle and spinnerets lighter than abdomen. Total length 8.2. Carapace 5.3 long, 3.3 wide. Sternum 3.6 long, 3.2 wide. Leg measurements: I: 3.80; II: 3.75; III: 3.1; IV: 4.1. Posterior unpaired claw elongated and dorsally reflexed ( Fig. 13HView FIGURE 13). PLS longer than PMSAbout PMS. Palp with a globose semi‒quadrate elongate bulb and an embolus longer than palpal tibia, with a wider base, strongly curved at middle, and strongly twisted on the distal two thirds ( Fig. 14B‒CView FIGURE 14), ending in three short extensions ( Fig. 13K‒LView FIGURE 13).

Female ( AMNHAbout AMNH): Carapace, chelicerae, labium, legs, coxae, endites and sternum as in the male. Abdomen as in male, but somewhat lighter. Anal tubercle and spinnerets lighter than abdomen. Total length 8.8. Carapace 5.8 long, 3.4 wide. Sternum 3.9 long, 3.3 wide. Leg measurements: I: 4.0; II: 3.85; III: 3.4; IV: 4.3. Posterior unpaired claws and spinnerets as in male. External genital area with sclerotized anterior plate and strongly sclerotized and wide lep, almost four times the spiracles width, remarkable ess ( Fig. 14EView FIGURE 14). Internal genitalia with wide invagination on receptaculum and uterus externus with narrow base ( Fig. 14FView FIGURE 14).

Natural history. All specimens from the type locality were collected under rocks in a small semi‒deciduous forest, behind the Hotel Montaña in Jarabacoa.

Distribution. Known only from the type locality ( Fig. 25AView FIGURE 25).
