Diagnostic description. Body strongly convex. Length 2.6–2.8 mm; greatest width 1.9–2.0 mm. Dark reddish brown, shining, with faint reticulate microsculpture on elytra. Head punctation moderately fine and dense. Antenna unicolorous dark reddish brown, club moderately robust; club segments 2 and 3 equal, wider than terminal (4 th) segment. Eyes large. Pronotum finely, moderately sparsely punctate; sides rounded, posterior angles rounded. Elytral striae not impressed, strial punctures large and closely spaced; only 5 th line of punctures reaching elytral base; interstriae minutely, sparsely punctate with a few scattered large punctures; epipleuron not punctate. Flight wings fully developed. Vertical face of mesosternum broad, not medially carinate. Metasternum coarsely, densely punctate with median impunctate area. Femora and tibiae not sexually dimorphic; male pro- and mesotarsi more densely setose ventrally. Mesofemur unmodified; mesotibia broad and strongly spinose, with an elongate, curved spine at inner apical margin. Metafemur slightly produced at apex of posterior margin; metatibia broad, spinose. First metatarsomere longer than second. First visible abdominal segment with about 3 irregular rows of nonfoveate punctures. Median lobe of aedeagus ( Fig. 48 ) elongate, broad, with paired apices inwardly curved. Parameres slender, straight, extending to apex of median lobe, each bearing two apical setae, one apical and one sub-apical. Inverted internal sac with pair of rodlike structures joined apically. Spermatheca of two connected spheres.
