28) Xiphidiopsis (Xiphidiopsis) dichotoma Jin View in CoL sp. n.

Holotype ♂ (right front and middle leg, both antennae lost): P.I., CAMARINES/ SUR, Mt., Iriga / 500–600m, 6.IV.62; H.M. Torrevillas / Collector / BISHOP

Paratype ♀ (left front and middle leg, both antennae lost): Labeled as Holotype

Diagnosis. General morphology typical of the genus. Male last abdominal tergite forming a single (unpaired) middle process, thick, bend strongly downward, apical part enlarged into 2 asymmetric triangular lobes, left one larger than right one; cerci complicated, asymmetry, a thin branch lobe and a broad apical lobe ( Fig. 14a, c, d View FIGURE 14 ), subgenital plate short, posterior margin slightly projected, with comparatively long styli ( Fig. 14e View FIGURE 14 ).

Female 9 th abdominal tergite without enlarged lateral posterior margin, subgenital plate elongate, narrowing toward end, posterior margin with a small notch in middle ( Fig. 14f View FIGURE 14 ), ovipositor thin sword shape, long and nearly straight, ventral valve smooth, without apical hook.

Measurement (mm). Body: ♂ 10.2, ♀ 13.0; Pronotum: ♂ 3.8, ♀ 3.5; Tegmina: ♂ 18.7, ♀ 20.8; Hind femora: ♂ 9.8, ♀ 11.1; Ovipositor: 9.6.

Comparison. Very close to X. (X.) monstrosa Karny, 1924 from southern Sumatera, but differs in detailed features of male last tergite and cerci. The obtuse triangular lobe of female subgenital plate also is similar to X. (X.) bicarinata Jin sp. n. from Philippines, but is much shorter.

Etymology. Species name refers to the shape of apical part of male last tergite forming 2 asymmetric triangular lobules.
