Diagnosis. General morphology typical of the genus. Male last tergite forming a single (unpaired) middle process, short, apical part enlarged into slightly asymmetric round lobes; cerci complicated, asymmetry, both with a basal long, thin lobule and apical 2 broader lobules (Fig. 13 a–d), subgenital plate short, posterior margin slightly projected, with comparatively long styli (Fig. 13d).

Female 9 th tergite with enlarged lateral posterior margin, subgenital plate with posterior margin projected in middle, forming a short ellipse lobe with a short median ridge (Fig. 13e), ovipositor thin sword shape, long and nearly straight, ventral valve smooth, without apical hook (Fig. 13f).

Measurements (mm). Body: ♂ 9.5–11.9, ♀ 10.1; Pronotum: ♂ 3.3–3.9, ♀ 3.3; Tegmina: ♂ 16.4–16.9, ♀ 17.4; Hind femora: ♂ 9.5–10.5, ♀ 10.0; Ovipositor: 7.5.

Comparison. This species is very similar to X. (X.) fallax and related species, but the middle process of male 10 th tergite with apical part enlarged into nearly symmetric round lobes, female subgenital plate projected forming smooth posterior margin, not pointed as in other species.

Etymology. Species name refers to male last abdominal tergite with apical part of middle process in inflated form.
