Discussion.
Corynoptera armigera
can be distinguished from all other species of the group by having the gonostylus clubshaped, in ventral view broadest far distal to the middle and only slightly narrowed toward the apex (
Fig. 3
B), and the specialized setae on the front tibial apex not arranged in a comb (
Fig. 6
A).
Corynoptera armigera
resembles
C. fera
and
C. robustior
in having the gonostylar megasetae very strong and not distinctly divided into two groups. It also can be distinguished from
C. fera
and
C. robustior
by having the tegmen subquadrangular, not much broader than long (
Fig. 3
A).
