Nomenclatural note. Wiesner (1988) described Th. kubani based on six specimens. Subsequentally, twenty-two additional specimens have been examined which exhibit highly variable elytral punctuation, as well as variability in the coloration of the labrum; based on this, the subspecies Th. tonkinensis kubani is placed into synonymy.

Diagnosis. Distinguished by the combination of short antennae, short humeral lunule, the angular central dot.

Re-description. Size: Total length (without labrum) 8.0 mm- 11.2 mm, (mean= 9.9 mm, n=31). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 278 View Figures 269-280 , females Figs. 279, 280 View Figures 269-280 ) as wide as long, completely yellow or blackish laterally, yellowish in the center, or completely black, with six apical teeth (seven in one female) and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally to elytral shoulders in males, somewhat shorter in the females, scape with a single apical bristle, antennomeres 2 to 5 glabrous, antennomeres 6 to 11 finely and evenly pubescent; scape yellowish above, black on underside, all the other antennal segments brownish or blackish. Distal two elements obviously enlarged in males. Clypeus glabrous. Frons smooth, with a transverse furrow in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, as long as wide, constricted in front and at back, transverse furrows strong, middle line and lateral lines nearly obsolete, middle line with several transverse short branches. Elytra: Shining black, in some specimens transparent brown apically, with basal and apical humps, distinctly punctate in front, shallower or absent in the apical half ( Fig. 270, 271 View Figures 269-280 ). Apex with angular lateral and sutural corner or lateral and sutural tooth, straight or slightly recurved between. Maculation yellow, composed of a short humeral lunule, basal dot, and angular central dot orientated perpendicular to the suture ( Figs. 272-276 View Figures 269-280 ). Apical margin sometimes yellow. Humeral lunule and basal dot are sometimes connected at the base. Ventral aspect: Venter black. Legs brownish yellow to dark, base of femora lighter. Aedeagus: ( Fig. 277 View Figures 269-280 ) curved, tip produced with a small hook, total length 2.3 mm.
