Figures 15–16
Description. Male. Body small. Fastigium verticis conical, with a narrow longitudinal furrow, apex obtusely rounded. Eyes spherical, projecting outwards. Apical segments of maxillary palpi slightly longer than subapical ones, apices faintly inflated (Fig. 15B).
Anterior margin of pronotum slightly arched, posterior margin rounded; lateral lobes longer than high, narrowing to backwards, humeral sinus indistinct (Fig. 15B).
Tegmina extending beyond posterior margin of pronotum, reaching the posterior margin of 2nd abdominal tergite or the basal area of 3rd abdominal tergite, posterior margin obtusely rounded (Fig. 15B). Hind wings absent.
Fore coxae with 1 small spine. All femora unarmed on ventral surfaces, apices of genicular lobes of hind femora obtusely rounded. Fore tibiae ventrally with 4 internal and 4–5 external pairs of spines and 1 pair of apical spines; tibial tympana open on both sides, ovoid. Middle tibiae with 4 pairs of spines and 1 pair of apical spurs on ventral surface. Hind tibiae with 18–24 internal spines and 19–24 external spines on dorsal surfaces, ventral surfaces of tibiae with 1–2 internal spines and 2–3 external spines, apices with 1 pair of dorsal spurs and 2 pairs of ventral spurs.
Posterior margin of tenth abdominal tergite slightly concave in the middle (Fig. 15E). Cerci short and basal half stout, slightly narrowing in lateral view, internal margins of basal half lobate extension with 1 small conical process on dorsal surface (Fig. 15E) and 1 wide lamellar process on ventral surface, the ventral process crossed each other, apices obtusely rounded and curved ventrally (Fig. 15D); apical half depressed, slightly curved inward and dorsad, apices subacute (Fig. 15F). Subgenital plate nearly trapezoidal with basal half broader, basal margin concave, lateral margins convex and rolled dorsally; posterior margins faintly projecting in the middle (Fig. 15I). Styli slender, apices subacute, inserted on both sides of posterior margins of subgenital plate (Fig. 15C).
Female. Similar in appearance to males, slightly larger than male. Ninth abdominal tergite with the apex of lateral margins expanding posteriorly (Fig. 16D). Cerci short and stout, conical, apices acute. Ovipositor moderately curved dorsally, stout at base, narrowing toward tip, dorsal valvulae acute at apices, ventral valvulae with a small hook at end (Fig. 16C). Subgenital plate transverse, posterior margin with a small concavity in the middle, the lateral lobe round (Fig. 16F).
Coloration. Body dark brown. Eyes brown. Antennal socket and internal margins of basal two segments of antennae black, flagellum with yellowish brown rings at apical area of each segment. Dorsal surface of head with four longitudinal black stripes, the external stripes fine and extending to the inside of antennal socket, inner stripes wide and fused at the apices of fastigium verticis. Disc of Pronotum with a longitudinal black-brown stripe on both sides, which reaching the middle of metazona. Apices of femora and tarsi light brown. Abdominal tergite dark, sternites dark brown.
Measurements (mm). BL: ♂ 6.4–7.5, ♀ 6.8–7.3; PL: ♂ 2.6–3.0, ♀ 3.7–3.9; TL: ♂ 2.5–2.7, ♀ 2.2–2.5; HFL: ♂ 6.7–7.7, ♀ 8.0–8.3; OvL: 4.5–4.6
Material examined. Holotype: male, Yakou, Cangyuan, Yunnan, August 14, 2021, coll. by Xiangyi Lu and Xiaojuan Huang. Paratypes: 3 males and 4 females, the other information as holotype.
Distribution. Yunnan (Cangyuan).
Discussion. The main differences between Phlugiolopsis bidentis and Phlugiolopsis chayuensis are in the shapes of male cerci and female subgenital plate.
Etymology. The species name is derived from Latin word “ sicul ” referring to the dorsal process of male cerci.
