Figure 6

Description. Male. Body small. Fastigium verticis conical, with a fine longitudinal furrow, apex rounded. Eyes hemispherical, projecting outwards ( Fig. 6A ). Apical segments of maxillary palpi longer than subapical ones, apices slightly inflated.

Pronotum short, anterior margin of pronotum straight, posterior margin obtusely rounded ( Fig. 6A ); lateral lobes longer than high, narrowing to backwards, humeral sinus indistinct ( Fig. 6B ).

Tegmina overlapped and concealed under the pronotum, reaching the posterior margin of 2nd abdominal tergite, apices rounded. Hind wings absent.

Fore coxae with 1 small spine. Apices of genicular lobes of hind femora obtusely rounded. Fore tibiae and hind tibiae ventrally with 3 internal and 4 external spines and 1 pair of apical spines; tibial tympana open on both sides, long oval, internal tympanum larger than external one. Hind tibiae with 25–26 internal spines and 23–24 external spines on dorsal surfaces, ventral surfaces with 2–4 pairs of spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.

Posterior margin of tenth abdominal tergite slightly rounded concave in middle ( Fig. 6D ). Cerci long, base stout, slightly narrowing, basal third with 1 digitate lobe on interno-dorsal margin, apices of the lobe pointing inwards ( Fig. 6D ), interno-ventral margin with 1 lobe ( Fig. 6H ); two thirds of apical area incurved, spine-shaped, apices subacute. Subgenital plate with basal half broader, narrowing toward tip, basal margin concave, lateral margins rolled dorsally, apical area projecting with posterior margin obtusely rounded ( Fig. 6G ). Styli long, basal half slightly stout, apices obtuse, narrowing toward tip, inserted on both sides of posterior margin of subgenital plate.

Female: Unknown.

Coloration. Body yellowish brown, with many small brown spots. Internal margins of antennal socket, scape and pedicel dark brown. Internal margins of flagellum dark brown with light brown rings on other segments. Dorsal surface of head with four longitudinal black brown stripes, inner stripes close to each other and fused at the apices of fastigium verticis, the external stripes extending to the inside of antennal socket. Pronotum blackish brown with a longitudinal brown stripe on both sides, which reaching the middle of metazona. Apices of femora blackish brown, basal and apical area of tibiae light black brown. Apices of genicular lobes of dark brown. Abdominal tergite light black brown, basal half of the lateral margins yellowish brown, apical half dark brown.Abdominal sternites blackish brown.

Measurements (mm). BL: ♂ 6.5–6.9; PL: ♂ 3.6–3.7; TL: ♂ 1.8–2.0; HFL: ♂ 7.8–8.2.

Material examined. Holotype: male, Yakou, Cangyaun , Yunnan, August 8, 2022, coll. by Xiangyi Lu and Xiaoyu Peng . Paratypes: 2 males, the other information as holotype.

Distribution. Yunnan (Cangyuan).

Discussion. The cerci of the new species are similar to Phlugiolopsis (Tribranchis) circolobosis Bian, Shi & Chang, 2013 (Chinese name: 圆叶吟ª), but differ from the latter by body with many brown spots, posterior margin of male subgenital plate rounded, apices inconspicuously protruding.

Etymology. Named after the type locality.
