Diagnosis

The species is similar to Phlugiolopsis complanispinis Bian, Shi & Chang, 2013 ( Fig. 8 ), but differs in male cercus expanded inwards on both dorsal and ventral surfaces of basal third, apices roundly triangular; female subgenital plate with small spine near basal area on lateral margins separately, its apex acute.

Etymology

The specific epithet of the new species is derived from the type locality Luojishan (Sichuan).

Description

BODY. Small.

HEAD. Fastigium verticis conical, apex rounded, furrowed on dorsal surface. Eyes oval, feebly protruding outward and forward ( Fig. 1A ). Apical segment of maxillary palpus nearly equal to subapical one in length, apex slightly swollen.

THORAX. Pronotum slightly elongate backwards, anterior margin feebly prominent, posterior margin rounded; lateral lobe longer than high, without humeral sinus ( Fig. 1B ).

TEGMEN. Tegmina short, terminals faintly surpassing posterior margin of pronotum, reaching middle area of second abdominal tergite, apices rounded ( Fig. 1B ). Hind wings absent.

LEGS. All femora unarmed on ventral surfaces. Fore coxa with 1 spine; fore and middle tibiae each with 5 external and 4 internal spines on ventral surfaces separately; fore tibial tympana open on both sides, oval. Genicular lobes of hind femur with apices rounded; hind tibia with 24–27 spines on both sides of dorsal surface separately, bearing 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

MALE ABDOMEN. Middle area of posterior margin of tenth abdominal tergite arc-shaped concave ( Fig. 1C ). Cercus expanded inwards on both dorsal and ventral surfaces of basal third, apices obtusely triangular; apical third of cercus cylindrical, apex rounded, obviously incurved ( Fig. 1C–D ). Subgenital plate with base broad, apical area narrowing; basal margin almost straight, lateral carinae distinct on basal half, middle area bulging ventrad, apical area arc-shaped protruding; styli short and conical, tips rounded, inserted on subapex of subgenital plate on ventral surface ( Fig. 1D ).

FEMALE ABDOMEN. Tenth abdominal tergite short, split in midline on posterior margin. Cercus conical, apex acute. Ovipositor short, gently curved upwards; both dorsal and ventral margins smooth, dorsal valvula slightly longer than ventral one, dorsal valvula with apex acute, ventral valvula with apex hook-shaped ( Fig. 1E ). Subgenital plate longer than broad, near basal area with small spine on lateral margins separately, its apex acute; basal margin faintly concave, posterior margin arc-shaped concave ( Fig. 1F ).

COLORATION. Body yellowish brown. Eyes black. Dorsal area of head with 4 longitudinal dark brown stripes. Scape and pedicel of antenna dark brown, flagellum with sparse annulate brown stripes, lamellar uplift on inner margin of antennal scrobe dark brown. Disc of pronotum with broad longitudinal brown stripe, posterior half slightly widened, lateral margins of two thirds anterior area of longitudinal stripe black. Genicular lobes black; tarsi dark brown.

MEASUREMENTS (mm). Body length: ♂: 6.2–7.1, ♀: 6.4–8.2; length of pronotum: ♂: 3.2–3.6, ♀: 3.2– 3.6; length of tegmen: ♂: 1.1–1.3, ♀: 1.2–1.4; length of hind femur: ♂: 6.6–7.5, ♀: 7.5–8.0; length of ovipositor: 6.1–6.9.

Distribution

China (Sichuan).
