Diagnosis
. This new species is similar to
S. palpalis
Papp
and
S. sumatrana
,
n. sp.
, by all three possessing a indistinct bump or minute dorsal antennal process, but it can be distinguished from them by the brown mesonotum (mesonotum yellow to reddish brown in
S. palpalis
and
S. sumatrana
) and the large obovate black male palpus (palpus smaller and differently shaped in
S. palpalis
and
S. sumatrana
).
