Diagnostic description. Body strongly convex. Length 1.2–1.7 mm; greatest width 0.9–1.3 mm. Reddish brown, pronotum darker, head nearly black; shining, without microsculpture. Head finely, moderately densely punctate. Antennal club robust. Eyes large. Pronotum finely punctate, punctures more dense laterally; sides rounded, posterior angles roundly obtuse. Elytral striae weakly impressed; strial punctures smaller medially, increasing in size laterally; interstriae minutely, sparsely punctate. Flight wings fully developed. Vertical face of mesosternum triangular ventrally, narrowing dorsally to form median carina that is continuous with median carina of horizontal face of mesosternum. Metasternum coarsely, irregularly punctate laterally; punctures fine and sparse medially. Posterior margin of meso- and metafemur of both sexes weakly expanded before apex. In both sexes, mesotibia broad and spinose; metatibia narrower, not strongly spinose. Male with more dense setae ventrally on pro- and mesotarsi. Median lobe of aedeagus ( Fig. 45 ) elongate, broad, narrowed apically; paired apices inwardly curved. Parameres slender, elongate, extending beyond apex of median lobe, each bearing 2 apical setae. Inverted internal sac with median urn-shaped structure, constricted and forked basally, containing 2 pairs of small sclerites. Spermatheca of 2 connected spheres.

Type material. Holotype, male, with the following label data: “ JAMAICA: Ocho Rios/ Fern Gully FIT/ 19.II–1.III.84/ D. Lindeman ” ( SBPC) . Paratypes (16) with same data as holotype ( SBPC).
