Type. Male holotypefrom Boca de Cabañas( 19°58′28″N, 75°54′35″W), Santiagode Cuba, Cuba, 21.xi.1999, A. Fong, ( BSC507). Male paratype, same data as holotype( BSC505)
Remarks. The first specimens examined of Nops pallidus n. sp.were those from Boca de Cabañas, Santiagode Cuba(BSC 505 and 507), which were assigned with doubt to Nops siboneyby Sánchez‒ Ruiz (2004), but were not included in the typeseries considering differences in size, color and shape of embolus. After examining additional material of Nops siboneyfrom eastern and central regions of Cuba, it is clear that the specimens from Boca de Cabañasremained distinct from true Nops siboneyand are here referred to Nops pallidus n. sp.
Additional material examined. CUBA: Santiagode Cuba: La Socapa( 19°58′18.1″N, 75°52′24.8″W), Bahía de Santiagode Cuba, 11.xii.2002, R. Teruel& A. Sánchez‒ Ruiz, 1 immature ( BSC 613). 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 siboneyand Nops gertschiby having a short and thick embolus, strongly curved; but can be distinguished by a less sclerotized tip ( Fig. 29B‒C) with the sclerotized margin wider and beveled ( Fig. 30B‒C).
Description. Male( holotype): Carapace, chelicerae, labium, coxae and legs pale yellow ( Fig. 29A). 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. 30D). PLS longer than PMS ( Fig. 29E). Femur I‒II slight elongated. Palp with embolus distinctly shorter than tibia, thick and strongly curved ( Fig. 29B‒C); beveled tip with a wide sclerotized margin ( Fig. 30B‒C). Female: Unknown Natural history. All specimens were collected under rocks or dead plants of Agavesp., in coastal and semi‒arid areas. At least the typespecimens coexist sympatrically with Nops guanabacoae.
Distribution. Known only from a few localities in Santiagode CubaBay and Boca de Cabañas( Fig. 29G), also possibly present in coastal and semi‒arid intermediate areas.
