Type depository. Holotype male in BMNH.

Type status. Holotype male! Type labels: “W. THAILAND: 300m., Thung Yai Wildlife Sanctuary . 15°28’N – 98°48’E.” [printed]; “ Tak Province, Umphang District, Song Bae Stream , 18-27.iv.1988.” [printed]; “Evergreen rain forest., M.J.D.Brendell, B.M.1988-183.” [printed]; “ Flight interception trap ” [printed]; “ THERATES rogeri PROBST and WIESNER , det. J. Wiesner 1994” [printed]; “HOLOTYPUS” [printed, red, with black borders]; “HOLOTYPE” [circular, printed, white, with red borders] .

Diagnosis. Distinguished from all other congeners in this group that have enlarged elytral maculation by the combination of pale ventrites and five apical teeth on labrum.

Re-description. Size: Total length (without labrum) 6.0 mm- 6.7 mm, (mean= 6.4 mm, n=2). Female unknown. Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 389 ) barely wider than long, yellowish, with five apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae extended posteriorally reach the basal half of the elytra, 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, distal two segments flattened. Clypeus glabrous. Frons smooth with two shallow bumps in the posterior part of the orbital plates, followed by a few longitudinal striae. Thorax: Pronotum shining greenish black, longer than 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 brownish black, with basal and apical humps, evenly punctate but somewhat shallower at the shoulders and at the apex ( Fig. 386 ). Apex with roundish lateral corner and sutural tooth, slightly recurved between them. Maculation composed of large brownish yellow humeral lunule which is connected to a brownish yellow basal dot, leaving a small blackish dot at the lateral margin of the basal humps, connected with a brownish yellow slanting central dot ( Fig. 387 ). The central dot is connected at the middle suture with the brownish yellow coloration of the apex, which reaches the apical humps. Ventral aspect: Venter yellowish, somewhat darker at the middle of the distal segments. Legs yellowish. Aedeagus: ( Fig. 388 ) straight, broadly rounded distally, total length 1.6 mm.

Distribution. Thailand (Tak).

Localities. THAILAND, Tak, Umphang District, Song Bae Stream , Thung Yai Wildlife Sanctuary , 18- 27.iv. 1988, 300m, evergreen rain forest ( BMNH) .
