Typelocality. Otoe Pasture, Noble Co., Oklahoma [ U.S.A.].

Type repository. Canadian National Collection, Ottawa (paratype examined).

Redescription. Length 3.0- 4.5 mm; stout, convex, moderately shiny, glabrous. Pale brownish red; legs reddish brown with palertarsi; antennal club yellowish. Headwith epistome feebly convex on disc, rather finely evenly punctured, punctation finer on disc; clypeus moderately sinuate at middle, subangulose at sides, thinly bordered, edge feebly reflexed at anterior angles, laterally shortly and sparsely bristled; genae broadly round, almost imperceptibly ciliate, not protruding from the eyes; frontal suture faintly indicate at middle; front evenly, finely punctured. Pronotum transverse, convex, dually, somewhat irregularly punctured; large punctures, twice to three times larger than small ones, denser and moderately coarser on sides, lacking on disc; small punctures, closer and coarser on sides, finer, very sparse and almost imperceptible ondisc; lateral margins feebly arcuate, finely bordered, edge glabrous; hind angles obtusely round; base very finely bordered, edge more or less widely interrupted medially. Scutellum irregularly, moderately punctured on basal half. Elytra convex, moderately tapered toward apex; striae moderately deep, rathercloselyfinely punctured, faintly crenulate; interstriaealmost flat, finely alutaceous, more strongly so on preapical declivity thus rather dull, very distinctly and rather closely punctured. Hind tibiae superior apical spur longer than first tarsal segment; latter as long as following three segments combined. Male: head and pronotum somewhat moresparsely punctured; elytral interstriae finely alutaceous, thus more shiny; metasternal plate moderately incavate; aedeagus Fig. 19-20 . Female: head and pronotumsomewhat moredensely punctured; elytralinterstriae more strongly alutaceous; metasternal plate almost flat.
