Diagnosis. Length (pronotum + elytra) = 1.55–1.68 mm; greatest width = 1.16–1.24 mm. Reddish brown, shiny. Head finely, sparsely punctate. Antennal club variable in width; antennomere 8 saucer-shaped, about half width of antennomere 9; apical antennomere longer than and almost as wide as 10. Sides of pronotum weakly rounded, posterior angles obtuse. Pronotum minutely, sparsely punctate. Elytral strial punctures coarse and closely spaced, striae distinct to base of pronotum; interstrial punctures minute, sparse. Metasternum coarsely, densely punctate laterally, finely punctate medially. Metatibia narrow, width at apex about twice width at base. Male mesotibial process moderately long, crossing over long tibial spine. Abdominal sternites III–VII each with a row of coarse punctures at base. Median lobe of aedeagus ( Fig. 6 ) broad with moderately long apical lobes. Parameres ( Fig. 6 ) narrow, not reaching apices of median lobe. Internal sac as in Fig. 6 .

Distribution. North American distribution ( Fig. 19 ): UNITED STATES. ALABAMA. NEBRASKA, OKLAHOMA

Previously recorded only from Latimer County, Oklahoma.

Seasonality. Adults are known from the months of March, May, and September.

Bionomics. The few collecting records suggest that adults occur in open and mixed forests. One specimen is from beach drift.

New material examined. We have examined three specimens with the following data: UNITED STATES. ALABAMA. Wilcox County, Camden, 24. III.1959, J. I. Cowger (1, USNM). NEBRASKA. Keith County, Arthur Bay, Lake McConaughy, 22. V.2008, R. Turnbow, beach drift (1, SBPC). OKLAHOMA. Latimer Co., IX.1990, K. Stephan (1, TAMU).
