Etymology. The specific name is a noun in apposition, derived from the type locality.

Diagnosis. Males resemble similar congener Nops hispaniola ( Fig. 24B‒C ) by having a short and curved embolus; but can be distinguished by having a differentiated texture on the surface of the median part, formed by several folds and lacking sclerotized margin ( Fig. 27E‒F ). Females with straight receptaculum, without invagination and uterus externus with wide base ( Fig. 27A‒C ). Males and females also can be distinguished by the unpaired claws elongated and dorsally reflexed on posterior legs ( Fig. 27I ).

Description. Male (holotype): Carapace yellowish orange. Chelicerae, labium, coxae and legs yellow. Endites and sternum yellowish orange ( Fig. 26A ). Abdomen light gray, dorsal pattern as in figure 6I but almost unnoticeable, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 8.8. Carapace 5.13 long, 3.08 wide. Sternum 3.2 long, 3.0 wide. Leg measurements: I: 3.7; II: 3.65; III: 3.2; IV: 3.95. Posterior unpaired claws elongated and dorsally reflexed. PLS same size as PMS. Palp with embolus shorter than palpal tibia, curved, with a differentiated texture on median part ( Fig. 26B ); narrow embolar tip ( Fig. 26B‒C ), with two ventral short extensions ( Fig. 27E‒F ),

Female (paratype): Carapace pale yellow. Chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 26D ). Anal tubercle and spinnerets whitish yellow. Total length 8.9. Carapace 5.3 long, 3.3 wide. Sternum 3.7 long, 3.2 wide. Leg measurements: I: 3.8; II: 3.75; III: 3.3; IV: 4.05. Posterior unpaired claws and PLS as in male. External genital area with weakly sclerotized anterior plate, strongly sclerotized lep and remarkable ess ( Fig. 26E ). Internal genitalia with receptaculum without invagination and uterus externus with wide base ( Figs 26F ; 27A‒C).

Natural history. Known specimens were collected under stones, in a semi‒desert savannah habitat from Jaragua National Park.

Distribution. Known from localities in Jaragua National Park, Dominican Republic ( Fig. 19A ).
