Figures 29A ‒FView FIGURE 29; 30A ‒D

Type. Male holotype from Boca de Cabañas (19°58′28″N, 75°54′35″W), Santiago de Cuba, Cuba, 21.xi.1999, A. Fong, ( BSC 507). Male paratype, same data as holotype ( BSC 505)

Remarks. The first specimens examined of Nops pallidus  n. sp. were those from Boca de Cabañas, Santiago de Cuba ( BSC 505 and 507), which were assigned with doubt to Nops siboney  by Sánchez ‒ Ruiz (2004), but were not included in the type series considering differences in size, color and shape of embolus. After examining additional material of Nops siboney  from eastern and central regions of Cuba, it is clear that the specimens from Boca de Cabañas remained distinct from true Nops siboney  and are here referred to Nops pallidus  n. sp.

Additional material examined. CUBA: Santiago de Cuba: La Socapa (19°58′18.1″N, 75°52′24.8″W)GoogleMaps  , Bahía de Santiago de Cuba, 11.xii.2002, R. Teruel & A. Sánchez ‒ Ruiz, 1 immature ( BSC 613View Materials)  . Ditto, 19.v.1997, R. Teruel, 1♀ immature (BSC 575). Boca de Cabañas (19°58′28″N, 75°54′35″W), 21.xi.1999, A. Sánchez ‒Ruiz, 1 immature (BSC 538).

Etymology. The specific name refers to the yellow pale coloration characteristic of this species.

Diagnosis. Males resemble similar congeners Nops siboney  and Nops gertschi  by having a short and thick embolus, strongly curved; but can be distinguished by a less sclerotized tip ( Fig. 29B ‒CView FIGURE 29) with the sclerotized margin wider and beveled ( Fig. 30B ‒CView FIGURE 30).

Description. Male (holotype): Carapace, chelicerae, labium, coxae and legs pale yellow ( Fig. 29AView FIGURE 29). Endites and sternum pale yellow. Abdomen pale gray, without noticeable dorsal pattern on abdomen, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 8.0. Carapace 5.1 long, 3.1 wide. Sternum 3.3 long, 3.0 wide. Leg measurements: I: 3.60; II: 3.55; III: 3.30; IV: 3.95. Posterior unpaired claws short ( Fig. 30DView FIGURE 30). PLS longer than PMS ( Fig. 29EView FIGURE 29). Femur I ‒II slight elongated. Palp with embolus distinctly shorter than tibia, thick and strongly curved ( Fig. 29B ‒CView FIGURE 29); beveled tip with a wide sclerotized margin ( Fig. 30B ‒CView FIGURE 30).

Female: Unknown

Natural history. All specimens were collected under rocks or dead plants of Agave  sp., in coastal and semi ‒arid areas. At least the type specimens coexist sympatrically with Nops guanabacoae  .

Distribution. Known only from a few localities in Santiago de Cuba Bay and Boca de Cabañas ( Fig. 29GView FIGURE 29), also possibly present in coastal and semi ‒arid intermediate areas.
