Diagnosis

This peculiar genus has species with a reduced to absent declivity and a pronotum that is grooved for the reception of the strongly procurved elytra.


Description

This genus ranges in length from 3.3 to 4.3 mm and approximately 1.5 to 1.6 times as long as wide. Their color is matte black. The pronotum is unarmed, grooved behind for reception of elytra. The scutellum is small. The crenulations of the anterior margin of the elytra are not well developed. The declivity is slightly convex and unarmed; the abdomen ascends to meet the apex of the elytra. The vestiture consists of recumbent and light-colored hair-like setae. The frons is ornamented by hair, which appear as curly tufts on females. The anterior margin of the compound eye is entire in species north of Mexico. The scape is shorter than the 7-segmented funicle. The symmetrical spatulate club has three procurved sutures. The procoxae are widely separated and the prothoracic precoxal ridge is not enlarged, but present.
