Phlugiolopsis procera sp. nov., Chinese name Ẋ板Þă

( Fig. 1 )

Description. Male. Body small. Fastigium verticis conical, apex rounded, furrowed dorsally. Eyes subglobular, prominent forward and outward. Apical segment of maxillary palpus slightly longer than subapical one, apical area lightly swelled.

Pronotum elongate backwards, anterior margin slightly prominent, posterior margin rounded; lateral lobe longer than deep, without humeral sinus. Tegmina short, apices slightly surpassing posterior margin of pronotum, reaching middle area of second abdominal tergite, apices rounded. Hind wings absent.

All femora unarmed on ventral surfaces. Fore coxa with 1 spine; fore tibia with tympana open and oval on both sides, with 5 outer and 4 inner spines on ventral surface. Middle tibia with 3 spines on inner margin and 5 spines on outer margin on ventral surface. Genicular lobes of hind femur with apices rounded; hind tibia with 21–23 spines on both sides of dorsal surface separately, bearing 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Tenth abdominal tergite with posterior margin feebly concave. Cercus expanded inwards on dorsal surface of basal half; interno-ventral surface with a stubby conical process near basal area, apex rounded; apical third of cercus cylindrical, almost rectangularly incurved, its interno-dorsal surface with a small tooth, tip acute; apex of cercus slightly acute. Subgenital plate with base broad, apical area narrowing; basal margin feebly concave, apical area triangularly protruding backwards, terminal slightly rounded; styli conical, apices rounded, inserted on apical third of subgenital plate on lateral margins.

Female. Lateral surfaces of eighth abdominal tergite on apical area with a digital projection separately. Tenth abdominal tergite short, posterior margin lightly concave. Cercus conical, apex acute. Ovipositor short, slightly upcurved; dorsal valvula with apex acute, apex of ventral valvula with a feeble hook. Subgenital plate broader than long, approximately rectangular; basal margin relatively straight, apical area angularly protruding backwards, apex rounded.

Coloration. Body yellowish brown. Eyes dark brown. Dorsum of head with 4 longitudinal dark brown stripes. Flagellum of antenna with sparse annulate brown stripes, lamellar uplift on inner margin of antennal scrobe dark brown. Disc of pronotum with a broad longitudinal brown stripe, anterior two thirds black on lateral margins, its posterior half pale and slightly widened. Genicular lobes black; tarsi black.

Material examined. Holotype: ♂, Fenshuiling, Jinping, Yunnan, 21 September, 2023, coll. Hao Xu. Paratypes: 1♂ 2♀, Fenshuiling, Jinping, Yunnan, 19 September, 2023, coll. Hao Xu and Yueting Duan. Other material: 1♂, Fenshuiling, Jinping, Yunnan, 22 September, 2023, coll. Yueting Duan ; 2♀, Fenshuiling, Jinping, Yunnan, 19 September, 2023, coll. Hao Xu.

Measurements (mm). Body: ♂ 8.6–9.2, ♀ 9.8–10.2; pronotum: ♂ 3.4–3.5, ♀ 3.7–3.9; tegmen: ♂ 1.2–1.3, ♀ 1.7– 1.8; hind femur: ♂ 7.6–8.2, ♀ 9.1–9.6; ovipositor: 6.5–6.7.

Discussion. The new species is similar to Phlugiolopsis yunnanensis Shi & Ou, 2005 , but it can be distinguished by near basal area of male cercus with a stubby conical process on interno-ventral surface, apex rounded; subgenital plate triangularly protruding on apical area, terminal rounded; female subgenital plate broader than long, approximately rectangular.

Etymology. The name of the new species refers to male subgenital plate protruding backwards on apical area, Latin “ procer- ” means protruding.

Distribution. China (Yunnan).
