Description

Members of the genus ''Brachyomus'' are easily confused with members of the genus ''Compsus''. Members of ''Brachyomus'' lack elytral shoulders and usually bear tubercles (four or more; there are only two in ''Compsus'' when they have them) on the broadest part of the elytra. They are usually covered by brown to whitish scales, forming some patterning; they can also bear metallic green or blue scales; some species have waxy secretions at the base of the elytral tubercles. There are thick scales rather uniform;y distributed all over the surface of the body, sometimes more densely so on the elytral tubercles. There is a key to identify most species in Faust (1892).

The genus ''Brachyomus'' is distributed in Colombia, Ecuador, French Guiana, Peru, Trinidad, Venezuela and Saint Vincent (Antilles), Saint Vincent
