Diagnostic description. Body strongly convex. Length 1.0– 1.1 mm; greatest width 0.7 mm. Yellow to light brown, shining, with faint reticulate microsculpture. Head finely, moderately sparsely punctate. Antennal club moderately robust. Eyes large. Pronotum finely, sparsely punctate; sides rounded, posterior angles rounded. Elytral striae weakly impressed; strial punctures large, closely spaced; interstriae finely, sparsely punctate. Flight wings fully developed. Vertical face of mesosternum broad, convex, not medially carinate. Metasternum coarsely, densely punctate laterally; punctures smaller medially. Mesofemur unmodified in both sexes. Male metafemur with toothlike process at apex of posterior margin; metafemur unmodified in female. In both sexes, meso- and metatibiae broad and spinose. Male with more dense setae ventrally on pro- and mesotarsi. Median lobe of aedeagus ( Fig. 57 ) elongate, broad, with inwardly curved, paired apices. Parameres slender, straight or weakly curved, reaching beyond apex of median lobe, each bearing 2 apical setae. Inverted internal sac with elongate rod-like structure divided in basal half. Spermatheca of two connected spheres.
