Diagnostic description. Body strongly convex; total length = 1.5–2.6 mm; greatest width = 1.1–1.9 mm. Yellowish brown to dark reddish brown, shining. Head moderately finely, densely punctate. Antenna with 10 antennomeres, antennal club robust, of 3 antennomeres; antennomere VII thin, about one-half as wide as VIII; apical antennomere distinctly narrower than IX. Pronotum finely, sparsely punctate; sides rounded, posterior angles roundly obtuse, base broadly rounded and sinuate laterally. Elytral strial punctures coarse, closely spaced; interstrial punctures minute, scattered. Metasternum moderately densely, coarsely punctate. Meso- and metatibiae broad and spinose. Abdominal sternites lack transverse rows of punctures. Aedeagus ( Fig. 30 View Figures 30–36 ) broad, curved and flattened dorsoventrally; acute tips of paired apical appendages inwardly curved. Parameres thin and broad, extending beyond apex of median lobe; each paramere with two apical setae. Males are distinguished by long, dense setae ventrally on pro- and mesotarsi, and by a tooth-like process at apex of posterior margin of metafemur.
