Remarks
. The new species is similar to
N. fuscus
sp. nov.
from Guangxi and
N. obscurus
Weele
from
India
in having wings almost entirely dark, but can be easily separated from
N. fuscus
by the black prothorax and acute tip of the aedeagus, and from
N. obscurus
by R3 and R4 which are curved backward at tip. In
N. fuscus
sp. nov.
, the prothorax is entirely yellow and the tip of aedeagus is blunt in lateral view. In
N. obscurus
, the Rs are nearly straight without any branch curved backward.
