Diagnostic description. Male. Habitus as in Fig. 10A View FIGURE 10 ; TBL 3.90 mm, FBL 2.36 mm; head black, pronotal disc, elytra and abdomen reddish-brown, antennomeres I–II, XI, mouthparts, pronotal posterolateral areas, and most parts of legs yellowish-brown. Head sub-triangular, HL 0.42 mm, HW 0.71 mm, with finely punctures in posterior portion; eyes prominent, EyL 0.14 mm; antenna elongate, AnL 1.98 mm, relative lengths of antennomeres I–XI: 1.25: 1: 1.5: 1.25: 1.25: 1.25: 1.25: 1.25: 1: 1: 1.5. Pronotum distinctly transverse, PL 0.71 mm, PW 1.27 mm, PI 0.56. Elytra slightly transverse, EL 1.08 mm, EW 1.22 mm, EI 0.88. Abdominal surface with microsculpture consisting of transverse waves; tergite VIII ( Fig. 11A View FIGURE 11 ) with four relatively long lobes, inner lobes much longer than outer ones; sternite VII ( Fig. 11B View FIGURE 11 ) shallowly and broadly emarginate at middle along posterior margin, granules evenly arranged in sub-semicircular area; sternite VIII ( Fig. 11C View FIGURE 11 ) with four lobes, deeply incised between inner lobes, median length of sternite 0.64 times as long as depth. Length of aedeagus ( Fig. 11 View FIGURE 11 D–E) 0.70 mm, parameres long and thin, slightly curved ventrally in lateral view, median lobe truncate at apex.
Female. General habitus ( Fig. 10B View FIGURE 10 ) similar to male. Measurements: TBL 3.77–4.24 mm, FBL 2.40–2.68 mm, HL 0.42–0.47 mm, HW 0.66–0.75 mm, EyL 0.14–0.19 mm, AnL 1.88–2.12 mm, PL 0.71–0.75 mm, PW 1.22–1.32 mm, PI 0.57–0.58, EL 0.99–1.18 mm, EW 1.22–1.32 mm, EI 0.81–0.89. Tergite VIII ( Fig. 11F View FIGURE 11 ) with four lobes, inner lobes slightly longer than outer ones, incision between inner lobes deep V-shaped, sternite VIII ( Fig. 11G View FIGURE 11 ) with six lobes, fimbriate lobes longer than others.
Comparative notes. As stated above, the new species is similar to T. curvipennis and T. drescheri in sharing elongate and thin parameres of the aedeagus. It differs from T. curvipennis in the slightly shallower incisions between the inner and outer lobes, and a much broader incision between the inner lobes of male sternite VIII; from T. drescheri in the much shallower median emargination of male sternite VII.
Distribution. China: Yunnan; Thailand: Chiang Mai ( Fig. 12 View FIGURE 12 ).
Etymology. The new species is dedicated to our colleague Liang Tang, who collected the male holotype.
