( Fig.1 View FIGURE 1 , Map 1)

Material examined. Holotype: ♂, Maguan, 104.00°E, 22.86°N, 19 June, 2024, Wenshan, Yunnan, coll. Hao Xu. GoogleMaps Paratypes: 1♂ 1♀, same data as holotype GoogleMaps . Other specimens: 2♂, same data as holotype GoogleMaps .

Description. Holotype Male. Body medium-sized for the subfamily, relatively strong.

Head. Fastigium verticis conical, apex rounded, with a thin longitudinal furrow on the dorsum. Eyes globular, protruding forwards ( Fig.1A–B View FIGURE 1 ). Apical segment of maxillary palpi slightly longer than subapical one, apex slightly swollen.

Thorax. Anterior margin of pronotum slightly straight while posterior margin rounded; metazona slightly raised; lateral lobe longer than high, posterior area narrowing, without humeral sinus ( Fig.1A–B View FIGURE 1 ).

Tegmina and Wings. Tegmen short, terminal slightly surpassing posterior margin of pronotum, reaching middle area of second abdominal tergite; hind wings absent ( Fig.1B, E View FIGURE 1 ).

Legs. All femora without spines on ventral surfaces. Fore coxa with a spine; fore tibial tympana open on both sides, fore tibia with 4 pairs of long spines on ventral surface, with 1 pair of short ventral apical spurs. Middle tibia with 4 pairs of long spines on ventral surface, with 1 pair of short ventral apical spurs. Apices of genicular lobes of hind femur with 1 spine on both sides separately ( Fig.1C, F View FIGURE 1 ), hind tibia with 18–21 short spines on both sides of dorsal surface separately, bearing 1 pair of dorsal apical spurs and 1 pair of ventral apical spurs.

Abdomen. Basal half of tenth abdominal tergite comparatively broad, middle area slightly narrow, apical half with a pair of broad and depressed lobes, apices rounded ( Fig.1G–H View FIGURE 1 ). Cerci incurved and crossing, basal areas strong, with a short and rounded process on outer surfaces respectively ( Fig.1H–I View FIGURE 1 ). Subgenital plate trapezoidal, basal margin slightly straight, basal area broad, narrowing, posterior margin slightly concave. Styli conical, inserted on ventral surface of subapical area of subgenital plate ( Fig.1I View FIGURE 1 ).

Paratype Female. Appearance is similar to that of male. Anterior and posterior margins near straight; metazona not raised ( Fig.1D–E View FIGURE 1 ). Cercus short conical. Ovipositor broad and short, moderately upcurved, both margins smooth, apex acute ( Fig.1K View FIGURE 1 ). Subgenital plate semi-circular, basal margin near straight, apex rounded ( Fig.1J View FIGURE 1 ). Tegmen short, terminal slightly surpassing posterior margin of pronotum, reaching middle area of second abdominal tergite; hind wings absent.

Coloration. Body may be green when alive. Eyes brown. Disc of pronotum with a pair of longitudinal black stripes, which widened at metazona and curved outwards ( Fig.1A–B, D–E View FIGURE 1 ). Spines and spurs of tibia black, apex of hind femur and base of hind tibia dark brown ( Fig.1C, F View FIGURE 1 ). Each abdominal tergite with a transverse brown stripe, eighth and ninth tergites broader and darker.

Measurements (mm). Body: ♂ 13.4–13.6, ♀ 13.6; pronotum: ♂ 5.5–6.0, ♀ 4.6; tegmen: ♂ 1.8–2.0, ♀ 1.9; hind femur: ♂ 12.0–12.2, ♀ 13.0; ovipositor: ♀ 7.2.

Distribution. China ( Yunnan).

Discussion. This new species resembles Cyrtopsis robusta Liu & Zhang, 2007 , but it differs from the latter in: basal half of male tenth abdominal tergite comparatively broad, middle area slightly narrow, apical half with a pair of broad and depressed lobes, apices rounded ( Fig.1G–H View FIGURE 1 ); cerci incurved and crossing, basal areas strong, with a short and rounded process on outer surfaces respectively ( Fig.1H–I View FIGURE 1 ).

Etymology. The name of the new species derives from the Latin latil- (broad) and -loba (lobe), referring to the morphology of posterior processes on male tenth abdominal tergite.
