Type material.

Complete label data for type material (holotype (MCZC), allotype and 231 paratypes) are provided in the original description.

Type locality.

Kenskoff, near Port-au-Prince, Ouest Department, Haiti, Hispaniola.

Diagnosis.

This subspecies is readily separated from other taxa of the opalinus species group on a combination of: small size, entire dorsal surface with bright metallic reflection and legs bicolored, femora darker than tibiae and tarsi.

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 39D. Clypeus and labrum with anterior margin of each shallowly concave. Antennae and mouthparts testaceous to rufo-testaceous. Legs bicolored, tibiae and tarsi testaceous to rufo-testaceous, femora infuscated, paler basally, remainder darker, rufo-brunneous to rufo-piceous. Dorsal and ventral surfaces rufo-brunneous to rufo-piceous, nearly piceous. Dorsally with metallic blue and green reflections, brighter than in S. f. cubanus , elytra additionally with iridescence; ventrally with iridescence. Head, pronotum and elytra shiny, without microlines visible at 100 ×. Pronotum with posteriolateral angles rounded; posteriolateral impression impunctate. Elytral striae impunctate, except the standard setigerous punctures in striae 2, 5 and 7. 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. 42 D–F. Apical portion of phallic median lobe long, narrowly triangular, symmetrically rounded in dorsal/ventral aspect, several minute subapical hooks on ventral surface; endophallus without darkened spine fields; without lamina; ostium anopic. Ventral surface of shaft smooth.

Ovipositor and female reproductive tract. Fig. 44A. Gonocoxite 2 (gc2) thick, moderately falcate. Bursa copulatrix (bc) moderately long; moderately long spermatheca (sp), with proximal swelling well above base, originating near base of common oviduct (co); long spermathecal gland duct originating about mid-length of the distal swelling of spermatheca. Spermathecal gland (spg) bulbous, with swelling of duct basad gland.

Geographical distribution.

Fig. 46. The range of this subspecies extends westward in the Greater Antilles from Hispaniola to Jamaica, and north-westward to North Caicos in the Turks and Caicos, and to Mayaguana Island and Rum Cay in the Bahamas.

Chorological affinities and relationships.

The three subspecies of S. flavilabris are allopatric in distribution. The range of this subspecies is overlapped by the ranges of S. fabricii and S. propinquus . Additionally, both this subspecies and S. integer are recorded from the eastern tip of Hispaniola. Relationships of S. f. ubancus are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 569 specimens (305 males, 264 females). See Appendix for details.
