In 1986 the Eustylini contained most of its current genera, mostly due to revised taxonomic placements made by Guillermo Kuschel.

[3][1] The latest additions were made by Franz in 2012 by transferring former members of other tribes including Geonemini, Phyllobiini, and Tanymecini.

[4] The type species of some genera (Compsus, Diaprepes, Eustylus, Exorides, and Exophthalmus) were redescribed by Franz.

10–25 mm); scale coverage highly variable in presence, density and coloration; iridescent scales, erect setae or waxy secretions are frequently present; surface smooth and even or strongly sculptured and irregular; head (including rostrum) subrectangular, nearly as long or longer than wide; eyes small to mid-sized, slightly dorsally positioned; frons usually as wide as or narrower than interantennal distance, often bearing median fovea; rostrum nearly parallel-sided or broadened apically; dorsal surface of rostrum with variable elevations or depressions, including longitudinal carinae or oblique fossae; antennal scrobe generally fully visible in dorsal view; nasal plate usually well developed, either depressed, flat or elevated regarding surface of rostrum; anterior margin of prothorax in lateral view straight, seldom slightly sinuate, never forming conspicuous postocular lobe; postocular setae may be present, if so, forming a fringe instead of a tuft; elytral shoulders usually well-developed, absent in Brachyomus, reduced in some Compsus and Exorides; tubercles and apical projections may be present on elytra; femora usually not toothed (except in some Eustylus).Eustylini ranges from south-western USA to Argentina, with its highest diversity in the Caribbean, Central America and northern South America.

The tribe Eustylini currently includes 25 genera and 339 sdescribed species:[3][4] This Entiminae-related article is a stub.
