Comments
. The original description of this species was based on one female. The
holotype
is on one slide under 3 coverslips.
This species appears similar to
O. curvialata
Lin (1994)
, but differs from the latter in having the fore wing 5.1× as long as broad, longest marginal fringe 2× as long as wing width, antennal clava broad, about 3.6×as long as broad (32:9), C1 shortest, C2 and C3 subequal in length (11:12), and ovipositor 2.91× as long as hind tibia (140:48). In
O. curvialata
the fore wing is 4.2× as long as broad, longest marginal fringe 1.3× as long as wing width, antennal clava narrow, about 4.7× as long as broad, C1 longer than C2, C3 longest, and ovipositor 2.67× as long as hind tibia.
