Antennal club flattened, sutures moderately to strongly bisinuate (occasionally procurved); eye small, finely faceted, sinuate on anterior margin, its width equal to much less than length of scape, its length equal to much less than twice length of scape; elytral declivity broadly, rather deeply excavated, margins acutely elevated and armed by three or more pairs of denticles, third pair on or incorporated into crest of lateral margin, lower margin of declivity rounded.
