Description:Asin S. perpauper nov.sp.

Length: 2.5-2.8mm (forebody: 1.4mm).

PM of the HT: HW: 28.5; DE: 14; PW: 21; PL: 21.5; EW: 26.5; EL: 22; SL: 16.

Male: Ventral characters as in S. perpauper . Aedeagus very similar so that of S. perpauper , apical portion of median lobe with a short, rounded, slightly prominent apex, distal portion of expulsion hooks slightly longer; parameres with 10 apical setae.

Female: Ventral characters as in S. perpauper . Spermatheca (fig. 52), infundibulum distinctly longer than in the compared species.

Comparative notes: This new species may be distinguished from S. perpauper by the slightly denser abdominal punctation: on tergite 7 interstices are about as large as punctures or only slightly smaller.

Etymology: Since it is a small inconspicuous species and very near to S. perpauper I name it " perpauperculus " (Lat. = very miserable).
