Description:Asin S. persculpturatus nov.sp.

Length: 2.8-3.3mm (forebody: 1.5-1.6mm).

PM of the HT: HW: 30.5; DE: 15.5; PW: 22.5; PL: 23; EW: 27.2; EL: 24; SL: 18.5

Male: Metasternum shallowly impressed, moderately coarsely, densely punctate. Ventral abdominal characters as in S. persculpturatus, but sternite 8 slightly deeper emarginate, emargination as deep as one fifth of the length of sternite. Aedeagus (fig. 25) very close to that of S. persculpturatus, but the apical portion of the median lobe more acute, the expulsion hooks different in shape.

Female: Sternite 8 at posterior margin triangularly projecting, apex nearly acute (fig. 9). Spermatheca (fig. 56), infundibulum short and broad.

Comparative notes:Inmostrespectsas S. persculpturatus, but the abdominal thread-like margination distinct and complete and the bump like elevated median portion of frons slightly broader impunctate. To identify this species examination of the sexual characters is necessary.

Etymology: Since the impressions on pronotum and elytra are very distinct, I name this new species " persculptus " (Lat. = distinctly sculptured).
