A revision of the Neotropical spider genus Nops MacLeay (Araneae: Caponiidae) with the first phylogenetic hypothesis for the Nopinae genera Sánchez-Ruiz, Alexander Brescovit, Antonio D.

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. 1848264113 [199,1359,223,248] La Socapa Cuba 19.971695 Santiago de Cuba 1 -75.87356 48 49 1 Santiago de Cuba 1848264126 2002-12-11 BSC R.
