Brachyomus is a Neotropical genus of broad-nosed weevils in the subfamily Entiminae, tribe Eustylini.[1]

Taxonomy

Brachyomus was described for the first time by Jean-Baptiste Henri Lacordaire in 1863 (p. 130).[2]

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).[3]

Distribution

The genus Brachyomus is distributed in Colombia, Ecuador, French Guiana, Peru, Trinidad, Venezuela and Saint Vincent[1][4][5]
