Female: Body more robust. Vertical diameter of eyes 1.6 times horizontal diameter and equal subocular furrow. Anterior margin of pronotum with distinct acute angular in middle. Tegmina shorter, extending over hind margin of the 1st abdominal tergite slightly, length 1.5 times its width, cover 4/5 tympanum. Length of hind femur 3.4 times its maximum width. Cercus short-conical, reaching end of epiproct. Subgenital plate oblong, hind margin with small acute angle in the middle. Ovipositor valve slender, apex angle, outer margin smooth.

Coloration: Body dark brown. tegmina dark brown. Hind tibia brown, upper and inner sides blue, outer side brown. Abdomen brown, with dark broad longitudinal stripe on both sides.

Measurement (in mm): Length of body: ♂ 29.5–30.7, ♀ 34.0–37.2. Length of tegmina: ♂ 5.1–5.4, ♀ 5.8–6.5. Length of hind femur: ♂ 13.9–14.1, ♀ 17.2–18.0.

Diagnosis. The new species is similar to Sulcotropis cyanipes Yin et Chou, 1979 . The major differences are listed in Table 7.

Etymology. The specific epithet is named after Xiaowutai the type locality.
