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. Aedeagus: ( Fig. 86 ) curved, with produced thick tip, total length 1.8 mm.
