Male. Body small. Head. Face ovoid, fastigium verticis conical, apex rounded, furrowed dorsally ( Fig. 12A ). Eyes nearly semiglobular, projecting outwards. Apical segments of maxillary palpi almost as long as subapical ones, apices slightly inflated ( Fig. 12B ). Pronotum. Elongate, anterior margin slightly arched, posterior margin narrowly rounded ( Fig. 12B ); lateral lobes longer than deep, narrowing to backward, humeral sinus absent ( Fig. 12B ). Wings. Most parts of tegmina concealed beneath pronotum, apices slightly surpassing posterior margin of pronotum, reaching the middle area of second abdominal tergite, apices obtusely rounded; hind wings absent. Legs. Ventral margins of all femora without spine. Procoxae swollen with 1 spine; tibiae with 4 internal and 5 external spines on ventral surface, apices ventrally with 1 pair of spurs. Mesotibiae ventrally with 4 internal spines, 5 external spines and 1 pair of apical spurs. Posttibiae with 31–36 internal and 31–33 external spines on dorsal surface, apices bearing 1 pair of dorsal spurs and 2 pairs of spurs. Abdomen. Posterior margin of tenth abdominal tergite faintly projecting with small median concavity. Cerci densely setose and short; basal area obviously stout, middle area suddenly terminating to the apex, apices obtuse and slightly curved inward ( Fig. 12E ); basal half area with a roughly semicircular lobe on interno-dorsal margin and a digitate lobe on interno-ventrad directly below ( Fig. 12F, G ). Subgenital plate longer than wide, nearly trapezoidal, lateral margins with basal areas convex and then narrowing, posterior margin subtrapezoidal projecting ( Fig. 12H ). Styli densely setose and roughly cylindrical, faintly curved forward, its apices obtuse, inserted at the subapical areas of subgenital plate on ventral surface ( Fig. 12G ). Genitalia membranous. Female. Unknown. Coloration. Body yellowish brown. Eyes dark brown. Antennae with brown rings on each segment. Dorsal surface of head with 2 pairs of longitudinal black brown stripes, the external stripes extending to the posterior margin of pronotum. Scapes and pedicelli dark brown. Disc of pronotum light brown between lateral stripes. Apices of femora and basal areas of tibiae brown. Apices of tegmina yellowish brown. Abdominal tergites brown. Basal area of subgenital plate brown and the apical area yellowish brown. FIGURE 12. Phlugiolopsis tridigitis sp. nov.

Measurements (mm). Body: ♂ 10.7 – 11.2; pronotum: ♂ 4.1 – 4.8; tegmen: ♂ 3.5 – 3.7; postfemur: ♂ 9.3 – 9.6. Distribution. Yunnan (Cangyuan, Gengma). Discussion. The new species can be distinguished from the other species of genus by the shape of male cerci. Etymology. The name of the new species is derived from the shape of male cerci.
