Phlugiolopsis clavata sp. nov., Chinese name 棒尾Þă

( Fig. 2 )

Description. Male. Body small. Fastigium verticis conical, apex rounded, with longitudinal sulcus on dorsum. Eyes oval, protruding forwards. Apical and subapical segments of maxillary palpus almost equal in length, apical area broadened.

Pronotum slightly elongate backwards, anterior margin relatively straight, posterior margin rounded; lateral lobe longer than deep, posterior margin tapering, humeral sinus absent. Tegmina short, apices slightly surpassing posterior margin of pronotum, reaching middle area of second abdominal tergite, apices rounded. Hind wings absent.

All femora without spines on ventral surfaces. Fore coxa with 1 spine; fore and middle tibiae each with 4 spines on inner side and 5 spines on outer side on ventral surfaces respectively; fore tibial tympana open and oval on both sides. Genicular lobes of hind femur with apices rounded; hind tibia with 27–32 internal spines and 33–36 external spines on dorsal surface, bearing 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

Tenth abdominal tergite with a broad and shallow concavity on posterior margin. Cercus short, slightly curved inwards; basal area with a conic process, apex faintly rounded; near basal area with a digital projection on interno-ventral surface, curved forwards; apical half of cercus clavate, slightly robust, apex rounded. Subgenital plate roughly trapezoid, basal margin concave, posterior margin slightly concave; styli conical, inserted on lateral margins of apical area of subgenital plate.

Female. Tenth abdominal tergite short. Cercus conical, apex acute. Ovipositor comparatively long, slightly curved dorsad; apex of dorsal valvula acute, ventral valvula with apex hook-shaped. Subgenital plate liguliform with basal margin roughly straight, near middle area obviously concave on lateral margins; the median carina distinct on apical half, posterior margin weakly concave.

Coloration. Body yellowish brown. Eyes dark brown. Dorsal area of head with 4 longitudinal dark brown stripes. Flagellum of antenna with sparse annulate brown stripes, lamellar uplift on internal margin of antennal scrobe dark brown. Pronotal disc with a broad longitudinal brown stripe, two thirds anterior area of longitudinal stripe dark brown on lateral margins, posterior half slightly widened. Genicular lobes black; tarsi dark brown.

Material examined. Holotype: ♂, Daxueshan, Yongde, Yunnan, 24 August, 2020, coll. Peng Cui. Paratypes: 2♂ 2♀, other data same as holotype . Other material: 4♂ 6♀, other data same as holotype ; 2♀, Daxueshan, Yongde, Yunnan, 23 August, 2020, coll. Peng Cui.

Measurements (mm). Body: ♂ 7.5–8.5, ♀ 8.4–8.5; pronotum: ♂ 3.5–4.0, ♀ 3.5–3.9; tegmen: ♂ 1.0–1.2, ♀ 0.8– 1.1; hind femur: ♂ 8.5–9.5, ♀ 8.4–9.5; ovipositor: 6.4–6.6.

Discussion. This species resembles Phlugiolopsis breviproceris Zheng, Shi & Chang, 2023 , it can be distinguished by male cercus with a conic process on dorsal surface of base, apex slightly rounded; apical half of cercus clavate, comparatively robust, apex rounded.

Etymology. The new species name is derived from apical half of male cercus being clavate, Latin “ clava- ” means clavate.

Distribution. China (Yunnan).
