Diagnosis. Distinguished by the combination of short humeral lunule and acutely angled central dot.

Re-description. Size: Total length (without labrum) 6.3 mm- 8.7 mm, (mean= 7.3 mm, n=65). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 87 , female Fig. 88 ) as wide as long, yellowish all over or somewhat blackish laterally, with six apical teeth (one male with seven teeth) and one lateral tooth. Labial and maxillary palpi yellowish. Antennae lanceolate, extending posteriorally behind 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 blackish. 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 black, with basal and apical humps, shallow punctate in front, nearly absent in apical half ( Fig. 82 ). Apex with or without angular lateral corner and sutural corner, in the first case somewhat recurved between. Maculation composed of a short yellow humeral lunule, a yellow basal dot, and a yellow central dot that is acutely angled inwards toward the suture ( Figs. 76, 77 ). Apex is transparent brownish or has a small yellow dot at the suture. Ventral aspect: Venter black, ventrites brownish marginally. Legs yellowish, tibiae and tarsomeres somewhat darkened distally.
