Diagnosis

In comparison with known species of the genus, the new species can be distinguished by male cercus expanded inwards on dorsal surface of basal half, long and narrow, its apex obtusely triangular; near middle area of female subgenital plate faintly concave on lateral margins, posterior margin roundly triangular.

Etymology

The specific epithet of the new species derives from its type locality Daweishan (Yunnan).

Description

BODY. Small.

HEAD. Fastigium verticis conical, apex rounded, furrowed dorsally. Eyes oval, protruding forwards ( Fig. 5A ). Apical segment of maxillary palpus and subapical one almost equal in length, apical area inflated.

THORAX. Pronotum slightly elongate, anterior margin roughly straight, posterior margin rounded; lateral lobe longer than high, with tapering posterior area, humeral sinus absent ( Fig. 5B ).

TEGMEN. Tegmina short, terminals not surpassing posterior margin of pronotum, apices rounded ( Fig. 5B ). Hind wings absent.

LEGS. All femora unarmed on ventral surfaces. Fore coxa with 1 spine; fore and middle tibiae each with 5 internal spines and 6 external spines on ventral surfaces separately; fore tibial tympana open and oval on both sides. Hind knees with apices obtuse; hind tibia with 2–3 internal spines and 5 external spines on ventral surface, and dorsal surface with 27–28 spines on inner margin and 30–33 spines on outer margin, bearing 2 pairs of ventral apical spurs and 1 pair of dorsal apical spurs.

MALE ABDOMEN. Tenth abdominal tergite with posterior margin concave. Cercus obviously incurved on basal two thirds; basal half of cercus with long and narrow lamellar expansion on interno-dorsal surface, its apex obtusely triangular; basal half of cercus with inward expansion on ventral surface, its posterior area with trapezoid process, apex truncate; apical third of cercus cylindrical, apex subacute, curved inward and dorsad ( Fig. 5C–E ). Subgenital plate longer than wide, basal margin concave, posterior margin slightly concave; styli comparatively long, inserted on ventral surface near lateral margins on apical third of subgenital plate ( Fig. 5D ).

FEMALE ABDOMEN. Lateral surfaces of eighth abdominal tergite on posterior margin with conic projection separately, apex rounded. Lateral surfaces of ninth abdominal tergite expanded backwards ( Fig. 5F ). Tenth abdominal tergite nearly straight on posterior margin. Cercus conical, apex acute. Ovipositor short, gently upcurved; dorsal and ventral valvulae almost equal in length, dorsal valvula with apex acute, apex of ventral valvula hook-shaped ( Fig. 5H ). Subgenital plate broad and short, middle wide, posterior area narrowing; basal margin feebly concave, lateral margins near middle area with notch, posterior margin obtusely triangular ( Fig. 5G ).

COLORATION. Body yellowish brown. Eyes blackish brown. Dorsal area of head with 4 longitudinal dark brown stripes. Flagellum of antenna with sparse annulate black stripes, lamellar uplift on internal margin of antennal scrobe dark brown. Pronotal disc with a broad longitudinal brown stripe, posterior half slightly widened, outer margins dark brown. Genicular lobes black; spines on tibia black; tarsi dark brown.

MEASUREMENTS (mm). Body length: ♂: 7.4–9.7, ♀: 7.9–8.2; length of pronotum: ♂: 4.3–4.6, ♀: 4.2– 4.3; length of tegmen: ♂: 1.7–1.9, ♀: 1.6–1.9; length of hind femur: ♂: 9.5–9.8, ♀: 9.6–9.7; length of ovipositor: 6.4–6.6.

Distribution

China (Yunnan).
