Cyrtopsis latilloba sp. nov., Chinese name Î叶刺Rdz

(Fig.1, Map 1)

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

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). 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).

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).

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), 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). Cerci incurved and crossing, basal areas strong, with a short and rounded process on outer surfaces respectively (Fig.1H–I). 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).

Paratype Female. Appearance is similar to that of male. Anterior and posterior margins near straight; metazona not raised (Fig.1D–E). Cercus short conical. Ovipositor broad and short, moderately upcurved, both margins smooth, apex acute (Fig.1K). Subgenital plate semi-circular, basal margin near straight, apex rounded (Fig.1J). 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). Spines and spurs of tibia black, apex of hind femur and base of hind tibia dark brown (Fig.1C, F). 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); cerci incurved and crossing, basal areas strong, with a short and rounded process on outer surfaces respectively (Fig.1H–I).

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.
