Diagnosis.
As pointed out by
Malicky (2010)
, this species is very similar to
Oecetis iphitos
Malicky 2005
and
Oecetis philoktetes
Malicky 2005
as all of these species belong to the
Oecetis testacea
Group and have a very similar color pattern on the forewings. However,
Oecetis asmada
has the dorsal branch of each inferior appendage very broad in lateral view, whereas in
Oecetis iphitos
each inferior appendage has the dorsal branch in the form of an equilateral triangle and
Oecetis philoktetes
has each inferior appendage with three tooth-like structures: one ventral, one dorsal, and one median tooth; from each of these teeth arises a very fine long appendage which is bent dorsad in lateral view.
Distribution.
India
(Andaman &
Nicobar Islands
).
