Diagnosis. Distinguished by the combination of yellowish margin of the ventral ventrites, brownish margin of the labrum, and elytral maculation with long basal dot.

Re-description. Size: Total length (without labrum) 6.5 mm- 7.5 mm (mean= 7.2 mm, n=3). Head: Shining greenish black. Mandibles yellowish, brownish distally in female, teeth brownish marginally. Labrum (male Fig. 286 , female Fig. 287 ) wider as long in male, as wide as long in female, margin brownish at base, remainder yellowish, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind elytral shoulders in female, somewhat longer in male, 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 black. 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 brownish black, sutural area near humeral lunule and central dot brownish, with basal and apical humps, distinctly punctate in front, shallower in the apical half ( Fig. 282 ). Apex with lateral and sutural corner, recurved between. Maculation composed of a long brownish yellow humeral lunule, long brownish yellow basal dot, and a yellow central dot which is acutely angled outwards toward the front ( Figs. 283, 284 ). Apex is yellow with this coloration reaching the apical humps. Ventral aspect: Venter black, ventrites brownish, yellowish at margin. Legs of male yellowish, hind femora, tibiae and tarsomeres somewhat darker distally. Legs of female brownish dark, only profemora and base of meso- and metafemora lighter.
