Remarks. Both Banks (1903) and Bryant (1940) list Oxyopes salticus in Cuba, and the latter even states that this species is relatively common in Havana and Soledad. Although I could not see any Cuban specimen collected before 1940, which could have been examined by them, I am confident these records can actually be attributed to O. crewi . I support this statement on the fact that, among the hundreds of specimens examined for this study; I did not find a single member of O. salticus from Cuba (see also Brady 1964: 479).

Diagnosis. Oxyopes crewi resembles O. salticus and O. incantatus sp. nov. (see O. salticus diagnosis), but can be distinguished by the pedipalpal tibia with a long ventral keel delimiting the retrolateral tibial scoop, the cymbial protrusion narrower apically and the basal embolic apophysis large, partially covering the embolus ( Figs 6 View FIGURE 6 A, B, 7A–C). Females can be recognised by the epigynum with the median process comparatively flattened and the lateral processes large, partially covering the median process in ventral view ( Figs 6 View FIGURE 6 C, D, 7D, E). As far as I could see, this is the only of the three species treated here that has females with damaged epigyna. Even in these cases, they can be recognised by the remains of the lateral processes ( Fig. 6 View FIGURE 6 F).

Description. Male (La Caoba, San Luis, Cuba, IBSP 165039). Carapace faint brown, with a median and a pair of lateral bands of brown cuticular scales. Pars cephalica with a lateral dark grey stripe and an anterolateral dark grey spot. Clypeus and chelicerae pale brown, with a pair of dark grey stripes from the anterior median eyes to the apex of the paturon. Endites faint brown, dark grey on the ectal margin. Labium dark brown. Sternum pale yellow, dark grey on the margins, near the base of coxae. Pedipalpal tibia orange, cymbium dark brown, remaining segments pale yellow. Legs yellow, femora I–III with a ventral, longitudinal dark grey stripe. Femur IV with basal and apical dark grey spots on venter. Opisthosoma dark grey, suffused with yellow spots and with a dark brown cardiac mark. Tegument moderately shiny, covered with smooth cuticular scales. Sides and venter dark grey. Spinnerets faint brown. Total length 3.66. Carapace 1.88 long, 1.45 wide. Tibia I length 1.6, II 1.42, III 0.99, IV 1.22. Opisthosoma 1.78 long, 1.14 wide. Ventral tibial apophysis with a large, oblique anterior keel, forming a retrolateral keel inside the retrolateral tibial scoop. Dorsal limit of the retrolateral tibial scoop with a triangular projection, retrobasal tibial apophysis triangular ( Figs 6 View FIGURE 6 A, B, 7B). Tegulum with a wrinkled retrolateral sector ( Fig. 6 View FIGURE 6 A).

Female (La Caoba, San Luis, Cuba, IBSP 165039). Colour as in male, except by the following. Ventral stripes on femora II and III interrupted in the middle, femur IV without ventral spots. Opisthosoma dorsally and laterally white, covered with sparse brown cuticular scales. Cardiac mark brown. Venter white, with a median dark grey band from the epigastric sulcus to the spinnerets. Total length 5.36. Carapace 2.16 long, 1.63 wide. Tibia I length 1.93, II 1.78, III 1.3, IV 1.32. Opisthosoma 3.2 long, 2.03 wide. Epigynum markedly sclerotised, ventrally bulging posteriorly to the median process ( Fig. 6 View FIGURE 6 C, D). Lateroposterior border with a marked ridge near the base of the lateral processes ( Fig. 7 View FIGURE 7 E). Copulatory ducts stout, with a sigmoid trajectory and mostly oriented dorso-ventrally ( Fig. 6 View FIGURE 6 E). Spermathecae rounded, with anterior glandular pores ( Fig. 7 View FIGURE 7 F) and one ectal Bennet’s gland pore. Fertilization ducts short, posteriorly directed ( Fig. 6 View FIGURE 6 E).

Variation. Colour varies from pale yellow to faint brown among both males and females. Females may show broken epigynal processes ( Fig. 6 View FIGURE 6 F). Subadult females have a pre-epigynum similar to the described above for O. salticus . Measurements: males (N=14), total length 3.2–4.58, carapace width 1.35–1.73. Females (N=10), total length 4.17–5.69, carapace width 1.4–1.73.

Natural history. There is no published information on this species’ natural history. A sample from Santiago de Cuba was labelled as collected by sweeping, indicating that specimens dwell on herbaceous or understory foliage. Two other samples, from Spanish Town ( Jamaica), were collected from nests of the hunting wasp Trypoxylon texense (Crabronidae) , the same wasp that was reported provisioning nests with Oxyopes salticus in Florida ( Kurczewski 1963). As mentioned for the other species, there is no information on sexual behaviour, but specimens with damaged epigyna ( Fig. 6 View FIGURE 6 F) suggest that males can break the anterior process during or after copulation. This kind of behaviour has been reported for other spider families ( Mouginot et al. 2015; Nakata 2016, and references therein) and can represent an attempt of impeding the female to copulate with subsequent males. If that is the case, it is plausible to suppose that the anterior process has some importance guiding the positioning of the male copulatory apparatus before intromission.

Distribution. Known only from Bahamas, Cuba, Jamaica, Hispaniola, and Saint Kitts & Nevis ( Fig. 10 View FIGURE 10 A), from where I could not find a single specimen of O. salticus . A recent record of O. salticus from Jamaica ( Crews et al. 2015) can represent the only exception to this distribution pattern, but this still requires a confirmation, since I have not seen the voucher specimens of that study. Based on the material examined here, it seems that Oxyopes crewi somehow replaces O. salticus on those islands, which are geographically surrounded by distribution records of the latter species. This is interesting, in view of the obvious high dispersal and invasive capacity of O. salticus . Considering the close proximity between O. crewi and O. salticus distribution records, it is possible that these species compete in nature and that, at least until now, O. crewi populations have been able to impede O. salticus invasion. This curious distribution pattern deserves a future investigation, based mainly on both species’ natural history and phylogeography.
