Figure 3 View FIGURE 3

Description. Male. Body small. Fastigium verticis conical, dorsal surface with indistinct median furrow ( Fig. 3A View FIGURE 3 ). Eyes spherical, projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices slightly inflated ( Fig. 3B View FIGURE 3 ). Thorax. Anterior margin of pronotum nearly straight, posterior margin rounded ( Fig. 3B View FIGURE 3 ); lateral lobes longer than high, narrowing to backward, humeral sinus absent ( Fig. 3B View FIGURE 3 ). Legs. Fore coxae with 1 small spine. All femora unarmed on ventral surfaces, apices of genicular lobes of hind femora obtusely rounded. Fore tibiae with 4 internal and 2–5 external spines on ventral surfaces; tibial tympana open on both sides, ovoid. Middle tibiae with 4–5 internal and 3–4 external spines on ventral surfaces. Hind tibiae with 22–29 internal and 23–31 external spines on dorsal surfaces, ventral surfaces with 4 pairs of spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Tegmina and wings. Tegmina short and slightly surpassing the posterior margin of pronotum, reaching the middle of second abdominal tergite. Hind wings absent ( Fig. 3B View FIGURE 3 ). Abdomen. Tenth abdominal tergite posteriorly projecting with a small concavity ( Fig. 3D View FIGURE 3 ). Cercus long, basal third expanded on internal margins, the interno-dorsal lobe semicircular, the interno-ventral lobe subtriangular with apical margin obtuse ( Fig. 3F View FIGURE 3 ); apical two-thirds terminating into a long spine curving inwards and upwards ( Fig. 3D View FIGURE 3 ). Subgenital plate transverse, lateral margins narrowing; posterior margin straight with prolonged median process which gradually upcurved ( Fig. 3E, G View FIGURE 3 ). Styli slender, apices obtuse, inserted on both sides of apical third on ventral surface of subgenital plate ( Fig. 3G View FIGURE 3 ).

Female. Ovipositor short, faintly upcurved behind middle area, dorsal valvulae with tip acute, ventral valvulae with a small hook at tip ( Fig. 3H View FIGURE 3 ). Subgenital plate subrectangular, lateral margins faintly converging, posterior margin truncate, ventral surface triangularly concave in middle ( Fig. 3K View FIGURE 3 ).

Coloration. Body brown. Eyes black. Dorsal surface of head with four longitudinal blackish brown stripes, the external stripes extending to the inside of antennal socket, inner longitudinal stripes wide and fused at apex of fastigium verticis. Disc of pronotum with a longitudinal blackish brown stripe on both sides, between them brownish. Apices of femora and tarsi black, tibial spines blackish brown.

Measurements (mm). BL: ♂ 7.9 – 8.2, ♀ 7.0 – 8.5; PL: ♂ 3.7 – 4.3, ♀ 3.6 – 3.8; TL: ♂ 1.2 – 1.4, ♀ 1.1 – 1.5; HFL: ♂ 8.1–8.4, ♀ 8.2–8.6; OvL: 4.8–5.4.

Material examined. Holotype: male, Dahaoping, Gaoligongshan, Baoshan , Yunnan, September 1, 2024, coll. by Yanting Qin and Ting Luo . Paratypes: 1 male and 3 females, the other information as holotype. Other specimens: 1 male and 1 female, the other information as holotype.

Distribution. Yunnan (Baoshan).

Discussion. The species resembles Phlugiolopsis montana Wang, Li & Liu, 2012 but differs in the following aspects: the prolonged process of male subgenital plate on posterior margin obviously narrower ( Fig. 3F View FIGURE 3 ) and gradually upcurved ( Fig. 3E View FIGURE 3 ).

Etymology. The new species' name derives from the male subgenital plate bearing a long posterior process.
