Type repository. Florida State Collection of Arthropods, Gainesville, Florida, U.S.A. (type not examined).

Redescription. Length 3.0– 3.5 mm; moderately elongate, convex, weakly shiny, pubescent. Dark brown; clypeal margin, legs and antennal club reddish brown. Head with epistome convex, coarsely granulate, superficially alutaceous between granules with semirecumbent hairs; clypeus slightly sinuate at middle, broadly round at sides, finely bordered, edge moderately reflexed, glabrous; genae obtusely round, rather shortly ciliate, protruding from the eyes; frontal suture weakly tuberculate mostly laterally; front rugosely, coarsely irregularly punctured. Pronotum transverse, convex, slightly dull, feebly depressed near anterior and posterior angles, densely, coarsely and somewhat irregularly punctured throughout; punctures with short recumbent hairs, the larger punctures faintly umbilicate; lateral margins arcuate, distinctly bordered, edge glabrous; hind angles obtuse; basal margin not bordered but marked by a series of deep, coarse and contiguous punctures. Scutellum coarsely irregularly punctured. Elytra convex, oval elongate, almost opaque, deeply striate; striae coarsely distinctly punctate, subcordately crenulate, nearly as wide as interstriae ( Fig. 10 ); interstriae subcariniform, with a double row of punctures bearing short recumbent hairs. Hind tibiae superior spur shorter than first tarsal segment; latter nearly as long as following two segments combined. Male: inferior spur of middle tibiae half length of superior and apically truncate; aedeagus Fig. 8–9 . Female: inferior spur of middle tibiae not so shortened and regularly acuminate.
