Mesosoma. Pronotum long, consisting of a single plate, 0.5× length of mid lobe of mesoscutum or as long as scutellum. Fore wing 4.66× as long as broad, with posterior margin strongly truncate at apex of retinaculum; marginal fringe 2× as long as wing width; hind wing with apex rounded and disc with hardly any setae, 17.33× as long as broad; marginal fringe 6.7× as long as wing width.

Comments
. This species is apparently similar to
O. curvialata
Lin (1994)
, but differs in the absence of a second line of setae on the fore wing disc, fore wing about 4.66× as long as broad with marginal fringe nearly 2× as long as wing width, apex of hind wing not pointed, and ovipositor more than 3× as long as hind tibia. In
O
.
curvialata
the fore wing disc has two lines of discal setae, fore wing 4.2× as long as broad with marginal fringe 1.5× as long as wing width, apex of hind wing normal, pointed, and ovipositor shorter, 2.67× length of hind tibia. However, the pronotum in
O. curvialata
can be membranous in the middle, and thus may actually belong to the subgenus
Oligosita
.
