Diagnosis. Distinguished from the nominate subspecies by the red brown elytral maculation.

Re-description. Size: Total length (without labrum) 7.5 mm- 8.6 mm, (mean= 8.1 mm, n=3). Head: Shining greenish black. Mandibles brownish, teeth blackish marginally. Labrum (male Fig. 206 , female Fig. 207 ) as wide as long, yellowish, with six apical teeth (one female with five teeth) and one lateral tooth. Labial and maxillary base brownish, palpi sometimes darker. Antennae extending posteriorly 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 brownish above, black on underside, all the other antennal segments brownish or darker. Clypeus glabrous. Frons smooth with two occasionally connected pits in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, nearly 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 with violet luster, with basal and apical humps, distinctly punctate in front, shallower in the apical half ( Fig. 203 ). Apex with lateral corner and sutural tooth, slightly recurved. Maculation composed of a large brownish humeral lunula extending from the marginal nearly to the middle suture, leaving open a blackish dot at the lateral margin of the basal humps, connected with a brownish yellow horizontal central dot with back margin that is orientated laterally toward the front and a light yellow apex, reaching the apical humps ( Fig. 204 ). Ventral aspect: Venter black, ventrites brownish marginally. Legs brownish, tibiae and tarsomeres somewhat darkened distally. Aedeagus: ( Fig. 205 ) curved, broadly rounded distally, total length 1.8 mm.
