Type area.

Americae insulis (the Antilles). Here restricted to the Lesser Antillean island of St. Barthélemy, the type area for S. chalybeus Dejean, a junior synonym of S. integer Fabricius.

Notes.

Bennett and Alam (1985: 20) and Peck (2009: 12) included Selenophorus affinis in their list of the Barbados beetle fauna. However, Peck (2009: 12) also noted that this probably was a misidentification. Selenophorus affinis , a member of the subgenus Hemisopalus , is known to occur in Panama, Colombia and French Guiana. We believe that the correct species name is Selenophorus integer , as it is the only member of the opalinus species group currently known from the Barbados.

Diagnosis.

This species is readily separated from the other sympatric species in the opalinus species group by dorsal microsculpture, elytral stria width and leg color. Specimens of Selenophorus f. flavilabris have visible microlines on the dorsal surface; specimens of S. fabricii have the elytral striae much wider preapically relative to on the disc; and specimens of S. propinquus have the tibiae darkened apically. Specimens of S. integer have no visible microlines on the dorsal surface, elytral striae the same width preapically as on the disc and the tibiae are unicolorous, not darkened apically.

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 40A. Clypeus and labrum with anterior margin of each shallowly concave. Antennae and mouthparts testaceous to rufo-testaceous. Legs rufo-testaceous to rufous, femur slightly darker than remainder of leg. Dorsal and ventral surfaces rufo-brunneous to rufo-piceous. Elytra with faint to moderate iridescence, varying with angles to light source. Ventral surface with very faint iridescence. Head, pronotum and elytra shiny, without microlines visible at 100 ×. Pronotum with posteriolateral angles rounded; posteriolateral impressions and laterally near the bead finely punctate, each puncture bearing a short, fine seta. Base of elytra, intervals 8 and 9 and apical portion of elytra with short, fine pubescence. Elytral striae impunctate, except the standard setigerous punctures in striae 2, 5 and 7. Elytral striae very narrow from base to apex, not widened preapically (Fig. 41B). Intervals with fine micro-punctures. Males with two terminal setae and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 43 A–C. Apical portion of phallic median lobe short, broad, symmetrical, with short medial projection curved ventrad; endophallus with one darkened microtrichial field, about medial, in dorsal aspect; without lamina; ostium anopic-right pleuropic. Ventral surface of distal 1/3 of shaft with two sharp ridges to apex.

Ovipositor and female reproductive tract. Very similar to that of S. opalinus , Fig. 44B, but enlarged portion of spermatheca longer, and narrow portion shorter than in S. opalinus . For details, see this topic for S. opalinus , below.

Geographical distribution.

Fig. 47. The known range of this species extends from Greater Antillean eastern Hispaniola eastward to the Virgin Islands, and then southward through the Lesser Antilles as far south as Grenada.

Chorological affinities and relationships.

The range of this species is overlapped by the ranges of the following members of the opalinus species group: S. fabricii , S. f. flavilabris , S. f. ubancus and S. propinquus Relationships of S. integer are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 1,625 specimens (632 males, 992 females, 1 unknown). See Appendix for details.
