Remarks.
This species is unique among all of the
Sepedon
species from
China
in lacking both orbital and scutellar setae. It is so different from other species of
Sepedon
that it might form the basis of a new genus if more supporting evidence accumulates in the future. This species occurs only in the south of
China
and apparently belongs to the
Oriental
fauna.
