Description:Sameasin S. perpusillus nov.sp. (see above).

Length: 2.4-2.9mm (forebody: 1.3-1.4mm).

PM of the HT: HW: 27.7; DE: 14; PW: 20.5; PL: 20; EW: 24.8; EL: 21; SL: 16.

Male: Ventral characters as in S. perpusillus . Aedeagus (fig. 26), median lobe triangulary narrowed toward rounded apex, expulsion hooks connected medially; parameres longer than median lobe, with 7-8 setae in apical quarter.

Female: Sternite 8 obtusely triangular at posterior margin. Valvifer with a moderately long tooth apicolaterally. Spermatheca (fig. 51).

Comparative notes: In most respects very similar to S. perpusillus, but the abdominal punctation denser and slightly less fine: punctures on tergite 4 as large as basal cross section of antennal segment 3, interstices distinctly smaller than punctures, punctures of tergite 7 slightly larger than one eye facet near medial eye margin, interstices distinctly smaller than punctures.- A reliable identification of this species is only possible by examining the sexual characters.

Etymology: Since this species is extremely close to S. perpusillus I name it " perpropinquus " (Lat.= very close).
