Diagnosis. Distinguished by the combination of elytral maculation with extremely laterally located central dot, and yellowish color of the marginal ventrites.

Re-description. Size: Total length (without labrum) 6.5 mm- 7.6 mm, (mean= 7.1 mm, n=2). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 151 , female Fig. 152 ) barely wider than long, yellowish, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish. Antennae extending posteriorally behind elytral shoulders in female, somewhat longer in the males, 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 darker, distal two segments in males flattened. 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. Elytra: Shining brownish black, with basal and apical humps, evenly punctate but shallower at the apex ( Fig. 148 ). Apex with angular lateral and sutural corner, slightly recurved between them. Maculation ( Fig. 149 ) composed of a large brownish yellow humeral lunula extending from the marginal to the middle suture, leaving open only a small blackish dot at the lateral margin of the basal humps, connected with a brownish yellow horizontal central dot with back margin slanting, orientated outwards toward the front and a light yellow apex, reaching the apical humps. Ventral aspect: Venter black, ventrites yellowish marginally. Legs yellowish, tibiae and tarsomeres somewhat darkened distally. Aedeagus: ( Fig. 150 ) curved, with long bulb distally, total length 1.7 mm.
