Type area.

"America boreali" (original citation). Here restricted to “Georgia”, the locality given for H. stigmosus , a junior synonym of S. palliatus .

Diagnosis.

This species is readily separated from the other members of the palliatus species group by the rounded posteriolateral angles of the pronotum, which are nearly rectangular in S. alternans , S. pyritosus and S. woodruffi .

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 49B. Clypeus and labrum with anterior margin of each shallowly concave. Head, pronotum and elytra with mesh pattern isodiametric. Mouthparts and legs testaceous to slightly darker; antennae darker than legs. Dorsal and ventral surface rufo-brunneous to brunneous; dorsal surface with faint cupeous metallic luster. Elytron bicolored, with apical fascia testaceous to slightly darker, length of pale marking nearly the same in intervals 2-9, forming a diagonal pale fascia; pale marking of interval 1 longer than that of interval 2. Elytral epipleuron pale, same color as the legs. Elytral striae impunctate, except the standard setigerous punctures in striae 2, 5 and 7. Punctures of striae 2, 5 and 7 foveate. Elytron with intervals impunctate basally near basal ridge. Males with two terminal setae and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 50 D–F. Very similar to those of S. pyritosus . For details, see this topic for S. pyritosus , below.

Ovipositor and female reproductive tract. Very similar to that of S. pyritosus , Fig. 52A. For details, see this topic for S. pyritosus , below.

Geographical distribution.

Fig. 53. This species is recorded only from Man-O-War Cay and North and South Bimini in the Bahamas in the West Indies.

Chorological affinities and relationships.

The West Indian range of this species is overlapped by the ranges of S. alternans and S. pyritosus , members of the palliatus species group. Relationships of S. palliatus are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 67 specimens (32 males, 35 females). See Appendix for details.
