Anterior margin of pronotum faintly projecting, posterior margin rounded (Fig. 2B); lateral lobes longer than high, narrowing to backward, humeral sinus absent (Fig. 2B). Legs. Fore coxae with 1 small spine. All femora unarmed on ventral surfaces, apices of genicular lobes of hind femora obtusely rounded. Fore and middle tibiae ventrally with 4–5 pairs of spines and 1 pair of apical spines; tibial tympana open on both sides, ovoid. Hind tibiae with 22–26 pairs of spines on dorsal surfaces, ventral surfaces with 2 internal and 2–3 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.

Tenth abdominal tergite faintly excavated on posterior margin (Fig. 2C). Basal half of cercus with interno-dorsal margin narrowly expanded (Fig. 2C), extending to the interno-ventral margin in middle area (Fig. 2F); apical half spiniform, gradually incurved (Fig. 2C). Subgenital plate longer than wide, lateral margins convex and then converging, posterior margin lobate projecting. Styli conical, curving forward, inserted on both sides of the posterior margin of subgenital plate (Fig. 2E).

Distribution. Yunnan (Gongshan).
Discussion. The species resembles Phlugiolopsis brevis Xia & Liu, 1993 but differs in the following aspects: basal half of male cerci narrowly expanded, the margins thickened and straight; posterior margin of male subgenital plate almost straight, not excavated; ventral surface of female subgenital plate concave on lateral areas instead of middle area.
Etymology. Named after the type locality.
