Female 9 th tergite with less enlarged lateral postal margin; subgenital plate elongated, narrowing toward apex, with 2 distinct lateral carinas, forming a long and narrow plate, round apex with a small incision in middle (Fig. 15b, c), ovipositor sword shape, long and nearly straight, ventral valve smooth, apical hook invisible.

Comparison. Comparing with 3 known species of Xiphidiopsis from Philippines, X. aglaia Hebard, 1922 from Basilan Islands, X. drepanophora Hebard, 1922 and X. gemmicula Hebard, 1922, from Mindanao, there is no female subgenital plate like this one, with 2 distinctive lateral carinas on it, forming a long and narrow plate, very characteristic, though no male could be matched with material available.

Etymology. Species name refers to female subgenital plate with 2 distinctive lateral carinas.
