Type locality. 4 mi. NW Coldwater, Comanche Co., Kansas ( U.S.A.).

Type repository. United States National Museum. Washington (type not examined).

Redescription. Length 4.5-5.0 mm; elongate convex, moderately shiny, almost glabrous. Yellowish brown, head and pronotum reddish brown, slightly darker, legs yellowish brown; antennal club dark brown. Head with epistome feebly gibbous on disc, anteriorly with trace of transverse carina, densely rugose distally, somewhat more slightly rugose and with irregularly immixed few coarse punctures on disc; clypeus deeply sinuate at middle with large, broad and blunt tooth at each side, thinly bordered, edge glabrous and feebly raised; genae obtusely round, sparsely shortly ciliate, protruding from the eyes; frontal suture barely distinct, faintly tuberculate; front densely coarsely evenly punctured. Pronotum transverse, moderately convex, slightly concave before hind angles, superficially alutaceous thus weakly shiny, dually densely punctured; large punctures, two to three times larger than small, denser on sides; small punctures almost evenly scattered throughout; lateral margins arcuate, rather thinly bordered, edge glabrous; hind angles obtusely round; base completely thinly bordered. Scutellum almost flat, distinctly punctured on basal half. Elytra moderately convex, feebly broadened posteriorly, shiny; striae deep, rather finely punctured, subcrenulate; interstriae almost flat, with row of dense, fine punctures on each side near striae, each puncture with fine, short, nearly invisible seta. Hind tibiae upper spur shorter than first tarsal segment; latter longer than following two segments combined. Male: fore tibiae spur relatively longer and abruptly curved downward; inferior spur of middle tibiae slightly bent inward before apex and in lateral view abruptly angled; pronotum relatively more transverse, less convex and less densely punctured; aedeagus Fig. 29–30 . Female: fore tibiae spur nearly straight; inferior spur of middle tibiae regularly acuminate; pronotum relatively narrower, more convex and more coarsely punctured.
