Diagnosis. From related T. vitalisi, T. biserratus and T. hunanensis sp. n. this species is clearly distinguished by the shape of antennomeres 9–11 (Figs 48, 49 vs. Figs 42–47), by colouration of hind femora (Figs 26, 28 vs. Figs 15, 17–19, 21, 22, 24, 25), by elytral pattern with only well-developed central dot (Figs 26, 28, 109–114 vs. Figs 15, 17–19, 21, 22, 24, 25, 99–108), as well as by the longer aedeagus with long thin apex (Figs 173, 174 vs. Figs 152–171).
Redescription. TL = 10.7–12.9 mm (mean = 11.55 mm, n = 10) in males, 11.5–12.9 mm (mean = 12.16 mm, n = 7) in females.
Head black with light blue-violet reflection; orbital plates indistinctly striated in posterior third; frons slightly elevated in anterior third (see above), slightly downward anteriorly (see at side), frontal sulci deep and slightly convergent in anterior half but shallow and widely divergent in basal half; occiput flat. Mandibles pale-yellow or yellow-reddish with brown teeth and apical molar. Labial palpi pale except brown apical palpomere; two basal palpomeres of maxillary palpi pale, palpomeres 3 and 4 light brown or brown. Antennae barely extend shoulders; scape pale on anterior side and brown-black on posterior side; antennomere 2 brown or dark-brown with lighter apex; antennomeres 3–6 dark-brown with light-brown apical third or brown-black with brown apices; antennomeres 9 and 10 in males with protruding downward anterior lower margins, in females barely dilated anteriorly; antennomere 11 in males slightly dilated with abrupt rough anterior margin (Fig. 49), in females elongated with wide rounded apex (Fig. 48). Labrum as long as wide, LW/LL = 0.93–1.08 (mean = 1.01, n = 17), black-brown with large apical yellow spot unseparated from central apical teeth; apical and lateral teeth red-brown (Figs 77–80).
Pronotum black with bright blue-violet reflection; indistinctly transverse, PW/PL = 1.0–1.1 (mean = 1.04, n = 17), apical lobe practically equal wide throughout; thorax black with violet reflection.
Fore femora pale with dark brown strip on posterior side of knees; middle and hind femora pale with dark brown knees; fore and middle tibiae dark brown with brown basal third or light brown with yellow-brown basal half, hind tibiae black or brown-black with violet tinge; tarsi black with violet tinge, in some specimens tarsomeres 1 and 2 brown-black with black apices; HTbL/HTaL = 1.10–1.20 (mean = 1.15, n = 13).
Elytra black with bright blue-violet reflection, sub-parallel or indistinctly divergent toward apex, EL/EW = 1.86–2.08 (mean = 1.95, n = 17); punctuation deep and regular between humeral hump and central dot, shallow and sparse in apical third; scutellum black with violet tinge; apical margin in males shortly cut, in females angularly rounded. Elytral pattern presented by short slightly oblique pale central dot as well as by very small and indistinct brownish basal portion of humeral lunule (see in front) in some specimens (Figs 26, 28, 109–114).
Aedeagus with long straight thin apex as well as with short lateral carinae (Figs 173, 174); AL = 2.9–3.2 mm (mean = 3.03, n = 7), EL/AL = 2.27–2.55 mm (mean = 2.41, n = 7).
Distribution. CHINA: Taiwan (Fig. 184).
