Diagnostic description. Body strongly convex. Length 1.0– 1.3 mm; greatest width 0.7–0.9 mm. Yellowish brown to reddish brown, shining, without microsculpture. Head finely, sparsely punctate. Antennal club moderately robust. Eyes large. Pronotum finely, sparsely punctate; sides rounded, posterior angles obtuse. 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 with coarse, irregularly spaced punctures laterally; punctures smaller medially. Male mesofemur weakly produced near base of posterior margin; mesofemur unmodified in female. Male metafemur with toothlike process at apex of posterior margin; metafemur unmodified in female. In both sexes, meso- and metatibia broad and spinose. Male with more dense setae ventrally on pro- and mesotarsi. Median lobe of aedeagus ( Fig. 50 ) elongate, broad, with inwardly curved, paired apices. Parameres moderately slender, weakly curved, extending beyond apex of median lobe, each bearing two apical setae. Inverted internal sac with elongate rod-like structure. Spermatheca tubular, weakly curved, weakly constricted at middle.
