Type depository. Holotype female in JWGC.

Type status. Holotype female! Type labels: “NE THAILAND, 1991, Ban Si Lang , 18. 5., Mae Hong Son, Leg. S. Bily ” [printed, with yellow borders]; “ THERATES , nigromarginalis, PROBST and WIESNER , det. J. Wiesner, 1994”; “HOLOTYPUS” [printed, red, with black borders] .

Diagnosis. Distinguished by the combination of dark outer margin of the labrum and connected elytral maculations.

Description. Size: Total length (without labrum) 6.0 mm-7.0 mm, (mean= 6.7 mm, n=6). Head: Shining greenish black apical part of frons behind clypeus with a reddish dot in some specimens. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 333 , female Fig. 334 ) as wide as long, dark brown, central part yellowish, with six apical teeth one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in male, 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 dark. Clypeus glabrous. Frons smooth with two shallow bumps 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 brownish black, in some specimens lighter at the apex, with basal and apical humps, distinctly punctate in front, shallower in the apical half ( Fig. 328 ). Apex with roundish lateral corner and area between sutural teeth nearly parallel. Maculation composed of a yellow humeral lunule, yellow basal dot, and slender yellow fascia-like central dot ( Figs. 329-331 ). The markings are usually connected and continuous, the color is brownish in those areas. Ventral aspect: Venter black. Legs yellowish, hind femora, tibiae and tarsomeres darker distally. Aedeagus: ( Fig. 332 ) curved, rounded distally, total length 1.4 mm.

Distribution. Myanmar (Karen), Thailand (Mae Hong Son).

Localities. MYANMAR, Carin Chebà , 900-1100 m, xii.1888 ( MSNG) ; THAILAND, Mae Hong Son, 20 km of Pai ( JWCG) , Mae Hong Son, Ban Huai Po, 30.iv.-4.v.1991, 1600-2000 m ( NHMW, ZSMC) , Mae Hong Son, Ban Si Lang , 23.-31.v.1991, 1200 m ( ZSMC) .

Remarks. A male from Myanmar, preserved in MSNG, bears the label “ Therates concinnus Gestro, 1888 , teste R. Gestro, 1893” and was used by Wiesner (1988:15, f. 61, 297, 394) erroneously as the concept of Therates concinnus . This specimen is placed herein into the series of Th. nigromarginalis .
