Antennae lanceolate, extending posteriorally behind elytral shoulders, 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. Clypeus glabrous. Frons smooth with two shallow bumps 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, middle line with several transverse short branches.
