Diagnosis

The new species is characterized by male cercus with expansion on basal half of dorsal surface, its posterior area lobate, apex rounded; subgenital plate with longitudinal concave in midline, protruding on subapical area, apical area curved ventrally, in middle of posterior margin with two triangular processes, terminals rounded.

Etymology

The specific epithet of the new species refers to the male cercus broad on the basal area, the Latin ‘ lata ’ meaning ‘wide’.

Description

BODY. Small.

HEAD. Fastigium verticis conical, apex rounded, furrowed dorsally. Eyes subglobular, prominent forward and outward ( Fig. 2A ). Apical segment of maxillary palpus nearly equal to subapical one in length, faintly swollen apically.

THORAX. Pronotum slightly elongate backwards, anterior margin feebly prominent, posterior margin rounded; lateral lobe longer than deep, without humeral sinus ( Fig. 2B ).

TEGMEN. Tegmina short, terminals slightly surpassing posterior margin of pronotum, reaching posterior margin of second abdominal tergite, apices rounded ( Fig. 2B ). Hind wings absent.

LEGS. All femora unarmed on ventral surfaces. Fore coxa with 1 spine; fore and middle tibiae each with 6 outer and 5 inner spines on ventral surfaces, respectively, fore tibial tympana open and ovel on both sides. Genicular lobes of hind femur with apices rounded; hind tibia with 2–3 internal spines and 6 external spines on ventral surface, and dorsal surface with 29–32 spines on inner margin and 33–35 spines on outer margin, bearing 1 pair of dorsal apical spurs and 2 pairs of ventral apical spurs.

MALE ABDOMEN. Tenth abdominal tergite arc-shaped concave on posterior margin. Cercus semicircular expanded inwards on basal half, its posterior area with small lobe, apex rounded; interno-ventral surface with digital projection near basal area, incurved near middle area, apex rounded; apical half of cercus spinous, rectangularly incurved, tip subacute ( Fig. 2C–D ). Subgenital plate with V-shaped notch on basal margin, in midline with longitudinal concave, lateral margins subparallel, subapical area protruding, apical area curved ventrally, posterior margin with two triangular projections, terminals rounded; comparatively long and conical styli inserted at ventral surface not far from apex ( Fig. 2D ).

FEMALE ABDOMEN. Posterior margin of tenth abdominal tergite feebly concave. Epiproct tongue-shaped with longitudinal sulcus on dorsal surface. Cercus conical, apex acute. Ovipositor comparatively long, faintly upcurved, dorsal valvula slightly longer than ventral one, dorsal valvula with apex acute, apex of ventral valvula hook-shaped ( Fig. 2F ). Subgenital plate roughly trapezoid; basal margin relatively straight, lateral margins faintly concave, posterior margin subobtuse ( Fig. 2E–F ).

COLORATION. Body yellowish brown. Eyes reddish brown. Dorsum of head with 4 longitudinal black stripes. Flagellum of antenna with sparse annulate black stripes, lamellar uplift on inner margin of antennal scrobe dark brown. Disc of pronotum with broad longitudinal brown stripe, its lateral margins black on anterior two thirds, posterior half pale and slightly widened. Genicular lobes black; tibial spines dark brown; trasi dark brown.

MEASUREMENTS (mm). Body length: ♂: 6.9–7.2, ♀: 6.4–9.6; length of pronotum: ♂: 3.8–4.0, ♀: 3.7–3.8; length of tegmen: ♂: 1.6–1.8, ♀: 1.2–1.7; length of hind femur: ♂: 9.5–10.0, ♀: 9.9–10.1; length of ovipositor: 6.2–7.3.

Distribution

China (Yunnan).
