Description
They are elongate, subcylindrical; clothed above and beneath with suberect hairs.[3]
Head exserted, perpendicular; anterior margin of clypeus with two acute flattened teeth, which partly cover the upper surface of the labrum; antennae subfiliform, clothed with coarse hairs, basal joint incrassate, second half the length of the first, subincrassate, third shorter than the fourth, following joints rather shorter; eyes with their inner margins slightly sinuate; terminal joint of palpi slender, ovate. Thorax subcylindrical in front, flattened, more or less excavated on the hinder half of the disc, lateral border obsolete, rarely visible at the base, its place supplied in the middle by two or more teeth. Legs moderate, stout; femora unarmed; basal joint of tarsi as long as the following two united claws more or less bifid. Prosternum greatly narrowed between the coxae.[3]
A well-marked genus on account of the toothed clypeus and similarly armed sides of the thorax.[3]
