Description. Male. Body small, head slightly obliquely backward. Fastigium verticis stout, apex obtusely rounded, dorsal surface with a narrowly longitudinal furrow (Fig. 3A). Eyes nearly globular, protruding forward. Apical segment of maxillary palp longer than subapical one, apex inflated. Anterior margin of pronotum slightly protruding forward, posterior margin narrowly rounded, posterior transverse sulcus obvious (Fig. 3A); lateral lobes longer than high, narrowing to backward, posterior margin oblique, without humeral sinus (Fig. 3B). Tegmina surpassing apex of abdomen, extending to one third of apices of hind femora (Fig. 3D), anterior margin expanded, posterior margin straight, apices obliquely rounded; hind wings shorter than tegmina, concealed under pronotum. Fore coxae with a small spine. All femora unarmed on ventral surface; apices of genicular lobes of hind femora obtusely rounded. Fore tibiae with 4 internal and 5 external spines on ventral surface, apical spines obviously shorter; tympana open on both sides, oblong, internal tympanum faintly larger than external one. Middle tibiae with 4 pairs of spines on ventral surface, apices with 1 pair of spines. Hind tibiae with 27–28 internal and 25–28 external spines on dorsal surface, ventrally with 2 internal and 4 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Posterior margin of tenth abdominal tergite arched concave (Fig. 3E). Genitalia membranous. Internal margin of basal half of cerci expanded (Fig. 3E), spoon-shaped in internal view (Fig. 3I); apical half pointing to dorsad, nearly cylindrical, apices subacute. Subgenital plate longer than broad; base transverse, obviously narrowing to apex, one third of base with a triangular membranous area in middle (Fig. 3H), midline of ventral surface obviously raised in two-thirds apical area, posterior margin faintly arched with numerous slender and long setae in middle (Fig. 3H). Styli small, nearly conical, apices obtuse, located on both sides of apex of subgenital plate (Fig. 3H).
Female. Body slightly larger, other characters are similar to male. Lateral margins of ninth abdominal tergite slightly extends to backward; middle of tenth abdominal tergite split; epiproct nearly circular. Cerci shorter, conical, apices acute (Fig. 4C). Ovipositor slender and long, straight, apices slightly curved dorsally, dorsal and ventral valvulae smooth, apices of dorsal valvulae subacute, apices of ventral valvulae hook-shaped (Fig. 4G). Subgenital plate subrectangular, basal margin arced concave, lateral margins slightly oblique, middle of posterior margin straight (Fig. 4E), the lateral lobes triangular, apices obtuse (Fig. 4F).
Coloration. Body yellowish brown. Eyes brown. Occiput blackish brown, reaching to the apex of fastigium verticis. Internal margins of antennal sockets, scape and internal margin of flagellum blackish brown, each segment of flagellum with brownish ring.Apices of femora brownish, bases and apices of tibiae and tarsi light brown. Spines of fore and middle tibiae light brown. Tegmina light brown, with blackish spots. Disc of abdomen light brown.
Measurements (mm). Body: ♂ 8.4–9.0, ♀ 10.6–11.3; pronotum: ♂ 3.0–3.2, ♀ 3.2–3.5; tegmina: ♂ 6.7–7.0, ♀ 7.6–7.9; hind femora: ♂ 7.8–7.9, ♀ 9.2–10.6; ovipositor: 11.7–11.9.
Material examined. Holotype: male, Pianma, Lushui, Yunnan, August 8, 2023, coll. by Siyu Pang and Ting Luo. Paratypes: 3 males and 4 females, other information is similar to holotype.
Distribution. Yunnan (Lushui).
Discussion. This species differs from other species of the genus by: posterior margin of male subgenital plate distinctly long, ventral surface of apical half raised along the midline, posterior margin with numerous setae in middle; posterior margin of female subgenital plate with 1 pair of large lateral lobes.
Etymology. The name of the new species derives from the posterior margin of male subgenital plate with numerous setae.
