Figures 5 – 6
Description. Male. Body small. Fastigium verticis conical, apex obtusely rounded, dorsal surface with 1 thin furrow along the midline (Fig. 5B). Eyes nearly semiglobular, projecting outwards. Apical segments of maxillary palpi as long as subapical ones, apices faintly inflated (Fig. 5C).
Pronotum elongate, anterior margin of pronotum faintly arched, posterior margin obtusely rounded, protruding backward; lateral lobes longer than deep, narrowing to backward, humeral sinus absent (Fig. 5B). Tegmina slightly surpassing the posterior margin of pronotum, reaching the middle area of second abdominal tergite, apices obtusely rounded and partly overlapped; hind wings absent.
Procoxae with 1 spine.All femora unarmed on ventral surfaces, apices of genicular lobes of postfemora obtusely rounded. Protibiae with 4 internal and 5 external spines on ventral surface, apices with 1 pair of ventral spurs; protibial tympana oval, opened on both sides. Mesotibiae with 2 internal spines, 4 external spines and 1 pair of apical spurs on ventral surface. Posttibiae with 25–27 internal spines and 25–29 external spines on dorsal surface, ventral surface with 3 internal spines and 4–6 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.
Posterior margin of tenth abdominal tergite projecting with a small median concavity. Cerci densely setose; basal half of cerci stout (Fig. 5D), interno-dorsal margin with semicircular expansion, the internal margin extending to ventral surface in middle area, interno-ventral margin with 1 finger-shaped process near base; apical half slender and spine-shaped which incurved, apices subacute (Fig. 5D). Subgenital plate longer than wide, narrowing posteriorly lateral margins terminating and about apical third area constricted, posterior margin with long and spine-shaped projecting, apices gradually upcurved and acute (Fig. 5J, L). Styli small, inserted on the ventral surface of apical third of subgenital plate.
Female. Seventh abdominal tergite with a small tubercule on each side; lateral margins of eighth abdominal tergite with an obvious tubercle at apices (Fig. 6F); lateral margins of ninth abdominal tergite with apices widely extending posteriorly, the margin of apical area widely rounded (Fig. 6I); tenth abdominal tergite narrow with posterior margin arced concave (Fig. 6F). Epiproct small and tongue-shaped, posterior margin rounded (Fig. 6F). Cerci very short and conical, gradually narrowing, apices acute. Subgenital plate roughly rectangular in ventral view, baso-lateral areas round and upcurved, the ventral surface concave, apical half with subparallel lateral margins with a median carina on ventral surface (Fig. 6I), posterior margin faintly angular concave, the lateral angels rounded (Fig. 6I). Ovipositor slightly upcurved behind middle area, dorsal and ventral margins smooth, dorsal valvulae with apices acute, ventral valvulae with a short hook (Fig. 6H).
Coloration. Body yellowish brown. Eyes dark brown. Dorsal surface of head with 4 longitudinal brown stripes: the internal stripes broad and fused to the apex of fastigium verticis, the external stripes extend to internal margins of antennal sockets (Figs. 5B, 6A). Pronotal disc with 1 pair of longitudinal black stripes, between the stripes brown. Abdominal tergites dark brown.
Material examined. Holotype: male, Darongshan, Beiliu, Guangxi, August 7, 2022, coll. by Qianwen Zhang and Shan Li. Paratypes: 5 males and 6 females, the other information as holotype. Other specimens: 3 males and 1 female, Darongshan, Beiliu, Guangxi, August 6, 2022, coll. by Qianwen Zhang and Shan Li; 23 males and 34 females, the other information as holotype.
Measurements (mm). Body: ♂ 8.1 – 9.7, ♀ 8.6 – 9.1; pronotum: ♂ 3.8 – 3.9, ♀ 3.7 – 4.9; tegmen: ♂ 3.3 – 3.5, ♀ 3.7 – 4.0; postfemur: ♂ 8.3 – 8.7, ♀ 8.6 – 9.4; ovipositor: 4.5–5.4.
Distribution. Guangxi (Beiliu).
Discussion. The new species differs from Phlugiolopsis (Longiloba) montana Wang, Li & Liu, 2012 by ventral process of male cerci small and finger-shaped at base; the posterior process of male subgenital plate long and narrow with apex acute; female subgenital plate subrectangular in ventral view, lateral margins of apical half subparallel lateral margins with median carina on ventral surface (Fig. 6I).
Etymology. The name of the new species is derived from the male subgenital plate with baso-lateral angles expanded.
