Description: About as in S. persubtilis nov.sp.

Length: 2.5-3.1mm (forebody: 1.4-1.5mm).

PM of a -PT: HW: 28,8; DE: 15; PW: 21; PL: 22; EW: 26.3; EL: 23; SL: 16.5.

Male: Ventral characters as in S. persubtilis . Aedeagus (figs 18, 19), apical portion of median lobe slightly different (short in single specimens), narrowly rounded at slightly prominent apex, expulsion hooks connected medially; parameres much longer than median lobe, with 8-9 long setae in apical half.

Female: Stenite 8 and Valvifer as in S. persubtilis . Spermatheca (fig. 59), infundibulum more than 3x as long as broad.

In nearly all respects very similar to S. persubtilis , except in the genitalia.

Comparative note: This new species should be identified by the aedeagus.

Etymology: This species is dedicated to its collector, Mr. H. Sugaya.
