Type material.

Complete label data for type material (holotype (FSCA), allotype, and 9 paratypes) are provided in the original description.

Type locality.

Cavehill, Parish of St. Michael, Barbados, Lesser Antilles.

Diagnosis.

This species is readily separated from the other species in the latior species group by a combination of: dorsal surface without visible microlines and pronotum with posteriolateral impressions finely punctate.

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 18A. Clypeus and labrum with anterior margin of each shallowly concave. Antennae, mouthparts and legs testaceous. Dorsal surface rufo-brunneous to brunneous; elytral disc with darker central cloud in intervals 1-6. Ventral surface rufous to rufo-brunneous; elytral epipleuron paler. Elytra and ventral surface with faint bluish iridescence. Head, pronotum and elytra shiny, microlines not visible at 100 ×. Pronotum with posteriolateral impressions finely punctate; posteriolateral angles rounded. Interruptions in the elytral striae give the appearance of punctures; standard setigerous punctures in striae 2, 5 and 7. Elytral intervals finely punctate. Males with two terminal setae and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 19 A–C. Apical portion of phallic median lobe long, narrowly tapered, symmetrically rounded in dorsal/ventral aspect, tip finely capped, bulb-like, dorsal flange turned up, hook-like; endophallus with one dark microtrichial field near basal bulb; lamina present, widened distally, rounded at apex. Ventral surface of shaft with two short rows of basad directed finely saw-toothed ridges.

Ovipositor and female reproductive tract. Not studied.

Geographical distribution.

Fig. 21. This species is known only from the Lesser Antillean islands of Barbados and St. Vincent.

Chorological affinities and relationships.

This species is the only member of the latior species group recorded from Barbados. Its relationships are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 12 specimens (5 males, 7 females). See Appendix for details.
