Phlugiolopsis spina sp. nov., Chinese name Ḧ板Þă

( Fig. 4 )

Description. Male. Body small. Fastigium verticis conical, apex rounded, with longitudinal sulcus on dorsal area. Apical segment of maxillary palpus subequal to subapical one in length, apical area inflated. Eyes globular, protruding forwards.

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

All femora without spines on ventral surfaces. Fore coxa with 1 spine; fore tibia with 5 inner spines and 6 outer spines on ventral surface; tibial tympana open and ovoid on both sides. Middle tibia with 5 inner spines and 5–6 outer spines on ventral surface. Genicular lobes of hind femur with apices rounded; hind tibia with 3 spines on inner side and 7 spines on outer side on ventral surface as well as 22–25 inner spines and 26–29 outer spines on dorsal surface, bearing 2 pairs of ventral apical spurs and 1 pair of dorsal apical spurs.

Tenth abdominal tergite short, posterior margin concave. Cercus slightly curved inwards, basal area stout, apical area narrowing; base with a lobate projection on interno-dorsal surface, apex rounded; subbasal area with a digital process on ventral surface, which curved forwards near middle area, apical area slightly thin, apex rounded; apical half of cercus cylindrical, apex rounded. Subgenital plate triangular with base broad and apex narrow; basal margin roughly straight, posterior margin rounded; styli conical and positioned on apical third of ventral surface.

Female. Tenth abdominal tergite short. Epiproct triangular, apex rounded. Cercus conical, apex acute. Ovipositor short, weakly curved dorsally; apex of dorsal valvula acute, ventral valvula with a terminal hook. Subgenital plate with basal margin relatively straight, lateral margins obviously concave, which bulged in the middle; basal third with a stubby spine on lateral margins respectively; posterior margin concave, apices of lateral lobes rounded.

Coloration. Body yellowish brown. Eyes reddish brown. Dorsal area of head with 4 longitudinal dark brown stripes. Scape and pedicel of antenna dark brown, lamellar uplift on inner margin of antennal scrobe dark brown. Disc of pronotum with a broad longitudinal brown stripe, which slightly widened on posterior area, lateral margins dark brown. Genicular lobes black; spines on tibia black; tarsi dark brown.

Material examined. Holotype: ♂, Xiaobazi, Maguan, Yunnan, 20 August, 2019, coll. Peng Cui. Paratypes: 1♂ 2♀, other data same as holotype . Other material: 1♀, Xiaobazi, Maguan, Yunnan, 20 August , 2019, coll. Peng Cui ; 2♂, Xiaobazi, Maguan, Yunnan, 21 August , 2019, coll. Peng Cui ; 1♂, Xiaobazi, Maguan, Yunnan, 6 August , 2022, coll. Mengjia Zheng ; 2♂, Nanwenhe, Malipo, Yunnan, 25 August , 2019, coll. Peng Cui.

Measurements (mm). Body: ♂ 6.5–7.7, ♀ 9.5–9.6; pronotum: ♂ 3.5–4.1, ♀ 3.8–4.0; tegmen: ♂ 1.4–1.6, ♀ 1.3– 1.7; hind femur: ♂ 7.9–9.1, ♀ 8.5–8.6; ovipositor: 5.3–5.8.

Etymology. The new species is named after female subgenital plate with a pair of spinous processes on basal third, Latin “ spina ” means spinose.

Discussion. This species resembles Phlugiolopsis circolobosis Bian, Shi & Chang, 2013 , but differs from the latter in male cercus with a short lobate process at base, apex rounded; subgenital plate triangular, apex rounded; female subgenital plate with a pair of spinous processes on lateral margins of one third base.

Distribution. China (Yunnan).
