Diagnosis. Length (pronotum + elytra) = 1.18–1.74 mm; greatest width = 0.86–1.28 mm. Yellowish to reddish brown, shiny. Head moderately coarsely, densely punctate. Antennal club darker than funicle; apical antennomere longer than and as wide as penultimate antennomere. Sides of pronotum rounded, posterior angles rounded; base rounded medially, weakly concave before posterior angles. Pronotal punctation fine and widely spaced. Elytral strial punctures deep and closely spaced, not clearly evident in basal one-fourth. Interstriae finely punctate. Metasternum coarsely, densely punctate; punctures finer medially. Metatibia widest from middle to apex, three times as wide as at base. Abdominal sternites III–VII each with transverse row of small punctures before apex. Median lobe of aedeagus (Fig. 12) broad, paired apices inwardly curved. Parameres extend to or slightly beyond apex of median lobe. Internal sac as in Fig. 12.

Seasonality. Adults have been collected from the months of April to October, with most in June to August, and early and late records are from more southern localities.
Bionomics. Adults have been collected in wooded habitats ranging from mixed deciduous, open pineland, and warm temperate bottomlands to mangrove-hammock transition and oak-palm hammock. They have been taken most often by flight intercept traps, evening car netting and ultraviolet light traps.
