pronotum basal sulcus absent, lateral antebasal foveae and median antebasal fovea reduced. Mesoventrite with median shield unmodified. Metaventrite afoveate, median flattened area declined posteriorly, margins thickened, metacoxae separated by extension of ventrite I. Legs unmodified. Elytra with single basal foveae and single sutural fovea present; discal stria present, short, sutural striae present.

tergites of usual form for tribe. Ventrite I covered in dense, shining setae; ventrite II with basal sulcus occupying length of ventrite, sulcus densely setose, deep longitudinal median sulcus reaching apex of ventrite, apex of ventrite with small median projection.
