Redescription. Length 3.0- 3.5 mm; slender, oval elongate, convex; head subshiny, pronotum weakly shiny, elytra dull; head glabrous, pronotumwith long sparse setae on sides, elytra biseriately pubescent. Piceous; clypeal margins and pronotal sides reddish-brown; elytra brownish; legs reddish-brown; antennal club testaceous. Head with epistome very superficially microreticulate thus almost shiny, faintly convex on disc, finely somewhat irregularly punctured; punctation finer distally, sparser on disc; clypeus very feebly sinuate at middle, round at sides, extremely finely bordered, edge distinctly upturned, glabrous; genae round, sparsely elongately ciliate, not protruding from the eyes; frontal suture finely impressed; front evenlysparsely punctured. Pronotum weakly transverse, convex, distinctly microreticulate thus weakly shiny, dually somewhat irregularly punctured but with a basal median narrow longitudinal impunctate areola, and with long, erect, sparse setae on sides near lateral margins; large punctures, three to four times larger than small ones, denser and coarser on sides; small punctures subregularly scattered throughout but more superficial on disc; lateral margins feebly arcuate, faintly crenulate, fimbriate with long, sparse setae; hind angles round, fringed with rather elongate setae; base feebly bisinuate, distinctly bordered, with fringe of rather long setae denser medially. Scutellum somewhat excavate, distinctly microreticulate thus almost dull, sparsely irregularly punctured. Elytra elongate, subparallel-sided, convex, strongly microreticulatethus dull; epipleural carina sparsely fringed by rather short setae; striae fine, superficially notclosely punctured, subcrenulate; interstriae flat with two rows of rough setigerous punctures; rows rather irregular on odd interstriae; most setae decumbent except some on odd interstriae. Hind tibiae superior apical spur shorter than first tarsal segment; latter as long as following three segments combined. Male: metasternal plate with median longitudinal groove somewhat more deep, posteriorly foveolate; aedeagus Fig. 24-25 . Female: metasternal plate with median longitudinal groove somewhat moresuperficial, posteriorly not foveolate.

Material examined. USA, Georgia: Camden Co., Little Cumberland I., 29.VII.1975, leg. W. E. Steiner (1 ex., DCGI) ; Jekyll Is., 17.VII.1971, leg. E. J. Ford Jr. (light trap) (1 ex., paratype, DCGI) .

Distribution. U.S.A. (Florida, Georgia).

Bionomics. Spring and summer species with bionomy almost unknown. The studied specimens of this extremely rare species were collected at light in July.
