Diagnosis. Distinguished by the combination of lanceolate antennae, short humeral lunule, darkened labrum, and the dark elytral apex.

Re-description. Size: Total length (without labrum) 8.0 mm- 9.2 mm, (mean= 8.6 mm, n=6). Head: Shining greenish black. Mandibles yellowish, brownish distally in females, teeth brownish marginally. Labrum (male Fig. 251 , female Fig. 252 ) as wide as long, dark, yellowish in the center, with six apical teeth and one lateral tooth. Labial and maxillary palpi yellowish.

Clypeus glabrous. Frons smooth, with a transverse furrow in the posterior part of the orbital plates. Thorax: Pronotum shining greenish black, barely longer than 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, distinctly punctate in front, shallower in the apical half ( Fig. 247 ), apex sometimes transparent brown.
