29) Xiphidiopsis (Xiphidiopsis) bicarinata Jin sp. n.

Holotype ♀ (right front leg lost): P.I., PALAWAN / 16km SE of/ Tarumpitao Pt. / 360 m. 20.V.1958; Light Trap / H.E. Milliron; Rain forest

Paratype ♀ (specimen pasted on paperboard): Same data as Holotype, but in hand writing

Diagnosis. General morphology typical of the genus. Lateral plate of pronotum with humeral sinus less distinct. Tegmina and wings long ( Fig. 15a ).

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.

Male unknown.

Measurements (mm). Body: ♀ 12.8–13.7; Pronotum: ♀ 4.0–4.1; Tegmina: ♀ 20.5–21.0; Hind femora: ♀ 12.5– 12.8; Ovipositor: 11.6–11.9.

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.
