Brentus anchorago is a long-snouted weevil, from the family Brentidae.

The adult is black in color, with longitudinal yellow marking on the elytra.

The species exhibits significant sexual dimorphism; the males are much thinner than the females.

This widespread neotropical species is known from Mexico, the West Indies and South America.

[4] It seems to be associated with the gumbo-limbo tree (Bursera simaruba), throughout its distribution.
