Description. BL = 10.3–11.8 mm, BW = 4.5–6.0 mm. Head, antennae, pronotum, scutellum, underside of body and legs yellow; apical portion of maxilla mandibles brown or black; elytra, tarsi, pro- and mesotibiae and apical portion of hind tibiae black; hind femora yellowish-brown; pubescence on head and pronotum yellow, on elytra black.

Head: eyes prominent, inner margin with distinct canthus; vertex finely and densely punctate, with a small deep median fovea; occiput slightly constricted; clypeus trapezoid, punctate and pubescent laterally; labrum subquadrate, sparsely punctate and pubescent; antennae reaching beyond elytral bases, antennomeres 1–4 cylindrical with sparse long setae, 5–11 strongly flattened and widened, densely pubescent, length of first antennomere 1.5x third antennomere.

Thorax: PW/PL = 1.3–1.4, PBW/PAW = 1.1–1.2; pronotum trapezoid, with anterior portion distinctly constricted laterally; pronotal anterior transverse groove deep laterally, obsolete centrally, posterior groove absent; pronotal disc slightly convex, slightly impressed along midline, sparsely punctate and pubescent except the midline, punctures finer than on vertex; lateral margin expanded from apex to base; each basal angle produced as a blunt tubercle. Scutellum trapezoid, slightly emarginate at apex, sparsely punctate and pubescent.

EL/EW = 1.4–1.7, elytral humeri broad, projecting antero-laterally; elytra laterally narrowed behind the humeri; apices rounded, divergent at the suture; disc convex, shiny, finely punctate and pubescent; epipleura finely punctate and pubescent. Metaventrite sparsely punctate and pubescent, each side raised to a prominent conical tubercle. Hind femora swollen, venter with two teeth on outer apex, basal one longer than apical one, lacking teeth on inner surface ( Figs 18, 20, 23 View FIGURES 17 – 24 ); hind tibiae curved in male, less so in female.

Abdomen: Apex of last abdominal sternite concave in female, rounded in male. Median lobe flattened, curved in lateral view ( Fig. 45 View FIGURES 45 – 50 ), sides and apex strongly sclerotised, dorsocentral portion membranous, sides parallel, apex triangular ( Figs 45–46 View FIGURES 45 – 50 ); median struts rod-shaped, widely separated from each other, 1.8 times as long as median lobe ( Fig. 45 View FIGURES 45 – 50 ); tegmen trapezoid, basal piece rod-like, tegminal ring gradually narrowed towards parameres, apical margin of parameres with dense setae ( Fig. 47 View FIGURES 45 – 50 ); endophallus membranous, with paired elongate stick shaped sclerites at base in repose. Spiculum relictum short, basal portion strongly sclerotised, apical portion rounded, weakly sclerotised. Ovipositor long, base broad, apex narrow, divided into two vaginal palpi, two baculi at each side connected at base, the outer short and weakly sclerotised, the inner long; coxite strongly sclerotised, cylindrical, apical margin with long setae, stylus small and distinct (Fig. 52).

Distribution. China (Guangxi, Sichuan, Yunnan); India (Assam); Myanmar (Kayin).

Remarks. The biology of this species is unknown.

Medvedev (2002) synonymized T. bidentata with T. flavicornis and we agree with this action based on photographs of type material ( Figs 17–23 View FIGURES 17 – 24 ). There is no significant difference between T. bidentata and T. flavicornis : the conical tubercles on the metaventrite are less developed ( Fig. 23 View FIGURES 17 – 24 ) in the former.
