Typelocality. Crescent City, Florida [ U.S.A.]. Type repository. United States National Museum. Washington (type not examined).

Redescription. Length 3.0-4.0 mm; oblong, convex, shiny, glabrous. Honey yellow to reddish-yellow; sutural margin of elytra brownish; legs reddish-yellow; antennal club yellowish. Head with epistome slightly convex, evenly regularly sparsely punctured throughout; punctures extremely fine, almost indistinct on disc; clypeus feebly sinuate at middle, obtusely round at sides, not bordered butmargin somewhat upturned, glabrous; genae round, sparsely elongately ciliate, not protruding from the eyes; frontal suture finely impressed, somewhat raised laterally; front more irregularly sparsely punctured than epistome. Pronotum moderately transverse, evenly, finely sparsely punctured; punctures somewhat more distinct and closer on sides; lateral margins feebly arcuate, rather thickly bordered, edge glabrous; hind angles obtusely round; base almostregularly arcuate, thinly bordered. Scutellum elongate, superficially microreticulate, finely sparsely punctured. Elytra distinctly tapered posteriorly, slightlytruncate at apex; epipleural carina fimbriate with elongate sparse setae; striae fine, superficially punctured, not crenulate; interstriae almost flat, very superficially microreticulate, very finely sparsely punctured. Hind tibiae superior apical spur not spatulate, shorter than first tarsal segment; latterlonger than following three segments combined. Male: pronotum somewhat more transverse and less convex; metasternal plate more deeply grooved medially and moderately incavate posteriorly; aedeagus Fig. 64-65 . Female: pronotum somewhat narrowed frontwardly; metasternal plate less deeply grooved medially, not incavate posteriorly.
