Description: About as in
S. persubtilis
nov.sp.
Length: 2.4-3.0mm (forebody:
1.3-1.4mm
).
PM of the HT: HW: 27.5; DE: 14.5; PW: 20.3; PL: 21; EW: 25.5; EL: 20.5; SL: 16.
Male: Ventral characters as in
S. persubtilis
. Aedeagus (fig. 31), apical portion of median lobe triangularly pointed, expulsion hooks connected medially; parameres with 8-9 apical setae.
Female: Sternite 8 and Valvifer as in the compared species. Spermatheca (fig. 58), about as in
S. persubtilis
.
In nearly all respects extremely similar to
S. persubtilis
, only the punctation on tergite7 is slightly finer and less dense, interstices often as large as punctures.
Comparative notes: This new species is clearly distinct from
S. persubtilis
by the aedeagus.
Etymology: Since this species is so closely resembling
S. persubtilis
I name it "
pervilis
" (Lat.= very cheap).
