Male: Metasternum shallowly impressed, coarsely and densely punctate. Sternites 3 and 4 very finely and very densely punctate and pubescent medially, sternite 5 with a shallow median impression, punctation and pubescence as previous, sternite 6 with a horse-shoe like impression in posterior two thirds, its punctation even finer and denser than in previous sternites, posterior margin very shallowly emarginate, sternite 7 with a broad and long median impression, punctation and pubescence as previous, posterior margin with a moderately deep, narrow posterior emargination. Sternite 8 with a narrow emargination nearly in posterior quarter of the sternite. Sternite 9 with moderately long apicolateral teeth. Aedeagus (fig. 24), apex of median lobe triangularly narrowed and curved dorsally, expulsion hooks connected medially; parameres slightly longer than median lobe, with 10-15 apical setae.

Comparative notes: Having regard to the variability in most respects as S. persculpturatus and S. persculptus . This species may be also distinguished from its close relatives by examining the sexual characters.
Etymology: Because this species is not very conspicuous I name it " pervenustus " (Lat. =very modest).
