Figure 56

Diagnostic description. Body strongly convex. Length 1.0– 1.2 mm; greatest width 0.8 mm. Light yellowish red to brown, shining, with faint irregular lines of microsculpture on pronotum and elytra. Head punctation moderately coarse and dense. Antenna of color of body to slightly paler, club slender. Eyes large. Pronotum finely, sparsely punctate; sides rounded, posterior angles obtuse. Elytral striae weakly impressed in apical three-fourths; strial punctures moderately coarse and dense; interstriae minutely, sparsely punctate. Flight wings fully developed. Vertical face of mesosternum convex, smooth; median carina of horizontal face extends slightly onto base of vertical face. Metasternum coarsely, densely punctate laterally, with dense pale setae medially. Male metafemur with strong, curved toothlike process at apex of posterior margin. Meso- and metatibiae broad and spinose in both sexes. Male pro- and mesotarsi slightly broader and more strongly setose ventrally than in female. Median lobe of aedeagus ( Fig. 56 ) elongate, broad, with paired apices inwardly curved at apex. Parameres slender, weakly sinuate in basal half, extending slightly beyond apex of median lobe, each bearing 2 apical setae. Inverted internal sac with short, urn-shaped, setose sclerite. Spermatheca of 2 connected spheres.
