Selenophorus cuprinus Dejean, 1829: 96. TYPE MATERIAL: not located in Chaudoir-Oberthür Collection (MNHP).- Gemminger and Harold 1868: 266.- Putzeys 1878a: 25 (established the synonymy).

Selenophorus subpunctatus Reiche, 1843: 143. LECTOTYPE: female, in Chaudoir-Oberthür Collection (MNHP), labelled: subpunctatus / Reiche Rev/ Cuv.[...illegible]//.- Gemminger and Harold 1868: 267. According to the original description, the provenance of this specimen is Venezuela, near Caracas ( Putzeys 1878a: 72 [entry in index]). This specimen was found among the members of S. discopunctatus , as recorded above, suggesting that it was regarded as conspecific with that species. However, Putzeys did not record the name in the synonymy of S. discopunctatus , nor did he include the name in the text of his treatment of Selenophorus . We treat it here as the name of a species incertae sedis.

Selenophorus chokoloskei Leng, 1915: 596. Synonymy established by Darlington 1935a: 161. According to Bousquet (2012: 1138) location of the syntypes is unknown.

Type area.

Saint Barthélemy, Leeward Islands, Lesser Antilles.

Diagnosis.

This species is readily separated from the other member of the discopunctatus species group by the posteriolateral impressions of pronotum, which are moderately to densely punctate, but smooth, not rugose. Additionally, apical portion of male genitalia with a prominent dorsal hook (Fig. 15A, C; cf. Fig. 15D, F).

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 14A. Labrum with anterior margin shallowly concave; clypeus with anterior margin moderately concave. Antennae and legs testaceous to slightly darker; palpi infuscated, tip testaceous, base slightly to much darker, maxillary palpomere 3 same color as base of maxillary palpomere 4. Dorsal and ventral surfaces brunneous to dark brunneous, not quite piceous; elytral epipleuron paler than disc. Frons and disc of pronotum shiny, with isodiametric microsculpture visible at 100 ×, microlines more impressed in females; posteriolateral impressions of pronotum with mesh pattern isodiametric; elytra granular, with mesh pattern isodiametric. Elytral striae impunctate, except the standard setigerous punctures in striae 2, 5 and 7. Punctures of striae 2, 5 and 7 foveate. Males with two terminal setae and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 15 A–C. Apical portion of phallic median lobe with long taper, symmetrically rounded in dorsal/ventral aspect, with prominent dorsal hook; endophallus with four long spines, approximately medial in position; lamina present, more or less banana shaped, pointed at apex.

Ovipositor and female reproductive tract. Very similar to that of S. yucatanus , Fig. 16. For details, see this topic for S. yucatanus , below.

Geographical distribution.

Fig. 17. This wide-ranging species is found on most of the island groups in the West Indies, with the exception of the Greater Antillean Caymans.

Chorological affinities and relationships.

The West Indian range of this widely distributed species overlaps the range of S. yucatanus in the Lesser Antillean Grenadines. Its relationships are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 1,435 specimens (714 males, 720 females, 1 unknown). See Appendix for details.
