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).
