Type material. HOLOTYPE, ♂— MYANMAR N (Burma), 65 km NW Putao, 1250 m, Zi Yar Dam vill., 18– 21.05.1998, leg. S. Murzin & V. Sinyaev (JW).

Diagnosis. This new species is reliably distinguished from T. vitalisi, T. biserratus, T. hunanensis sp. n., T. sauteri and T. motoensis by apex of aedeagus without lateral carinae (Fig. 131 vs. Figs 152–174). From T. fruhstorferi and T. pseudovitalisi sp. n. this new species is recognized by thin apex of aedeagus (Fig. 131 vs. Figs 115–130 and Figs 132–135, respectively) as well as by the rough punctuation of the elytra (Figs 12, 96 vs. Figs 1, 3–11, 81–95).

Description. TL = 10.6 mm. Head black with distinct violet reflection; orbital plates finely but distinctly striated in posterior third; frons semi-circular, with distinct impression and transverse rugoses (see above), slightly downward anteriorly (see at side), frontal sulci very deep, distinctly convergent in anterior half and shallow and sharply divergent posteriorly; occiput flat with shallow impression anteriorly. Mandibles dark brown underside, yellow-pale topside, with brown teeth and apical molar. Labial palpi pale with dark-brown apical palpomeres; maxillary palpomeres 1 and 2 light brown, palpomeres 3 and 4 dark brown. Antennae not extend shoulders, black, antennomeres 1–5 with light violet tinge and brown apices, antennomeres 9–11 club-shaped, antennomeres 9 and 10 serrated, with downward anterior lower margins, antennomere 11 clearly dilated with abrupt apical margin (Fig. 35). Labrum as wide as long (LL = LW— 1.4 mm), black-brown with large elongate apical yellow spot unseparated from central apical teeth (Fig. 64).

Pronotum shining black with blue-violet reflection; as wide as long (PL = PW— 1.9 mm), apical lobe slightly wider in medial part; thorax black with distinct blue reflection.

Fore femora pale along anterior margin and black with violet tinge along posterior margin; middle femora pale in basal half and black with violet tinge in apical half; hind femora pale in basal third and black with violet tinge in apical 2/3; tibiae black with distinct violet lustre; tarsi black with light violet tinge except brown apices of all apical tarsomeres; HTbL/HTaL = 1.22.

Elytra black-blue with bright purple-violet reflection; indistinctly divergent in apical third, EL/EW = 1.94 (EL = 6.6 mm, EW = 3.4 mm); punctuation deep and regular in basal 3/4 except humeral area, in apical quarter shallow and tenuous; scutellum black with violet tinge, apical margin rounded but shortly top-cut. Elytral pattern presented by small pale basal portion of humeral lunule (see in front) and relatively short practically transverse central dot indistinctly dilated in lateral portion (Figs 12, 96).

Aedeagus (only apical half) with thin elongate slightly sinuate rounded apex, without lateral carinae (Fig. 131).

Female unknown.

Etymology. This new species is named after the type locality—Zi Yar Dam village.
