Diagnosis. From related T. vitalisi , T. sauteri and T. hunanensis sp. n. this species is best distinguished by smooth orbital plates, by the shape of antennomeres 9–11 ( Fig. 44 View FIGURES 29–49 vs. Figs 42, 43, 45–49 View FIGURES 29–49 ), and by the shape of aedeagus ( Fig. 168 View FIGURES 152–174 vs. Figs 152–167, 169–171, 173, 174 View FIGURES 152–174 ). Moreover from T. sauteri and T. hunanensis sp. n. this species is distinguished by yellow spot of labrum distinctly separated from central apical teeth ( Figs 73, 74 View FIGURES 73–80 vs. Figs 75–80 View FIGURES 73–80 ), and from T. hunnanensis sp. n. —by entirely black hind tibia and tarsi ( Figs 22, 24 View FIGURES 15–28 vs. Fig. 25 View FIGURES 15–28 ) as well as by narrow apical dot not extending to the suture ( Figs 22, 24 View FIGURES 15–28 , 105, 106 View FIGURES 99–114 vs. Figs 25 View FIGURES 15–28 , 107, 108 View FIGURES 99–114 ).

Redescription. TL (according to the original description) = 13.5 mm in male, 14.5 mm in female; TL (studied specimen) = 11.1 mm in male.

Head black with distinct blue-violet reflection; orbital plates smooth; frons plain and semi-circular (see above), slightly downward anteriorly (see at side), frontal sulci rather deep, slightly convergent in anterior 2/3; occiput slightly impressed anteriorly. Mandibles brown underside, pale topside with brown teeth and apical molar. Labial palpi pale with brown apical and basal palpomeres; maxillary palpi brown except pale palpomere 2. Antennae barely extend posteriorly to the shoulders, scape light-brown on anterior side and brown-black on posterior side; antennomere 2 black-brown; antennomeres 3–5 brown with light violet lustre and light brown apices, antennomeres 9–11 short, broad and flattened, anterior lower margins of antennomeres 9 and 10 in males sharply serrated, antennomere 11 very wide and sharply abrupt anteriorly ( Fig. 44 View FIGURES 29–49 ); in female barely dilated and protruding. Labrum in male as long as wide, LW/LL—1.03, with straight lateral margins, black-brown with medium-sized yellow apical spot narrowly separated from central black apical teeth ( Figs 73, 74 View FIGURES 73–80 ).

Pronotum shiny black with bright blue-violet reflection; slightly transverse, PW/PL = 1.1 (PW = 2.2 mm, PL = 2.0 mm), apical lobe practically equal wide throughout; thorax black with distinct violet reflection.

Fore femora pale along anterolateral margins and black-brown with violet lustre along posterior margin; middle femora pale in basal third, yellow-brown on posterior side and black-brown with violet lustre in 2/3 apical part on anterior side; hind femora black with violet reflection in apical 2/3 and pale in basal third; fore and middle tibiae light brown on dorsal side and dark brown on ventral side with brown-black apices and light violet tinge; hind tibiae black with violet lustre; tarsi brown-black with violet tinge; HTbL/HTaL = 1.2.

Elytra black with bright violet-purple reflection; indistinctly divergent toward apex, EL/EW = 1.87 (EL = 7.1 mm, EW = 3.8 mm); punctuation of elytral disc deep and regular between basal humps and central dot, then shallow and sparse, in apical quarter indistinct and irregular; scutellum black-brown; apical margin shortly cut. Elytral pattern presented by four isolated pale spots: triangular basal portion of humeral lunule, distinct basal dot separated from the suture, wide prolonged and distinctly oblique central dot as well as narrow not extend the suture apical dot ( Figs 22, 24 View FIGURES 15–28 , 105, 106 View FIGURES 99–114 ).

Aedeagus with very short slightly curved blunt apex and short lateral carinae ( Fig. 168 View FIGURES 152–174 ); AL = 2.5 mm; EL/AL = 2.84.

Distribution. CHINA: Guizhou Province (Jiangkou and Yinjiang Counties) ( Fig. 184 View FIGURES 184 ).
