Phlugiolopsis nanlingensis sp. nov., Chinese name Oi岭Þă

( Fig. 3 )

Description. Male. Body small. Fastigium verticis conical, apex rounded, with median sulcus on dorsum. Eyes nearly globular, slightly protruding forward. Apical segment of maxillary palpus roughly equal to subapical one in length, apical area inflated, apex truncate.

Pronotum longer, anterior margin approximately straight, posterior margin rounded; lateral lobe longer than high, humeral sinus absent. Tegmina short, terminals slightly surpassing posterior margin of pronotum, reaching posterior margin of second abdominal tergite, apices rounded. Hind wings absent.

All femora unarmed on ventral surfaces. Fore coxa with 1 spine; fore tibia with 5 internal spines and 6 external spines on ventral surface; both sides of tympana open and oval. Middle tibia with 6 external spines and 4 internal spines on ventral surface. Hind femur with apices of genicular lobes rounded; hind tibia with 24–27 spines on both inner and outer sides on dorsal surface, with 2 pairs of ventral apical spurs and 1 pair of dorsal apical spurs.

Tenth abdominal tergite with posterior margin concave. Cercus with a semicircular expansion on dorsal surface of basal third; near middle area with an irregular process on interno-ventral surface, which broader on basal half and narrow on apical half; apical third of cercus cylindrical, obviously incurved, apex acute. Subgenital plate subtrapezoidal, basal margin with a V-shaped membranous area, posterior margin feebly concave; styli comparatively long, inserted on ventral surface of apical third of subgenital plate near lateral margins.

Female. Tenth abdominal tergite short, posterior margin concave. Cercus conical, apex acute. Ovipositor short, slightly curved upwards; apex of dorsal valvula acute, apex of ventral valvula hook-shaped. Subgenital plate rectangular on basal half, apical half narrowing; basal margin comparatively straight, which concave on lateral margins; posterior margin faintly concave.

Coloration. Body yellowish brown. Eyes reddish brown. Dorsal area 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, the longitudinal stripe widened on posterior area, lateral margins dark brown on anterior two thirds. Genicular lobes black; tarsi dark brown.

Material examined. Holotype: ♂, Nanling, Ruyuan, Guangdong, 27 August, 2020, coll. Lidan Zhang. Paratypes: 1♂, Mangshan, Yizhang, Hunan, 30 August, 2020, coll. Lidan Zhang ; 1♀, Mangshan, Yizhang, Hunan, 24 July, 2023, coll. Chun Chen. Other material: 1♂, Mangshan, Yizhang, Hunan, 24 July, 2023, coll. Chun Chen.

Measurements (mm). Body: ♂ 6.3–8.3, ♀ 6.7; pronotum: ♂ 3.3–4.0, ♀ 3.5; tegmen: ♂ 1.1–1.3, ♀ 1.0; hind femur: ♂ 7.2–7.9, ♀ 8.1; ovipositor: 5.6.

Discussion. This new species is really similar to Phlugiolopsis damingshanis Bian, Shi & Chang, 2012 , but differs from the latter in male cercus semicircular expanded inwards on basal area; ventral surface with an irregular process, which broader on basal half and narrow on apical half. Yet for Phlugiolopsis damingshanis Bian, Shi & Chang, 2012 male cercus expanded inwards on dorsal surface of base, apex roundly triangular; ventral surface with a compressed process, apex rounded.

Etymology. The new species name is derived from its type locality Nanling.

Distribution. China (Hunan, Guangdong).
