Achlyodidini
Genus Guides
1Achlyodidini is a tribe of in the Pyrginae, characterized by unusually-shaped wings with squarely truncated forewing tips and often vivid coloration. The tribe comprises approximately 16 and is restricted to the Americas, primarily in tropical regions. Formerly included within a broad concept of Pyrgini, Achlyodidini is now recognized as a distinct tribe based on phylogenetic studies, though it remains the closest relative to Pyrgini sensu stricto. The tribe includes notable genera such as Eantis (sicklewings) and Achlyodes.

Identification
The squared-off forewing tips are diagnostic for the tribe and immediately distinguish Achlyodidini from other Pyrginae tribes. The combination of this wing truncation with bright coloration separates them from the more drab Pyrgini sensu stricto. Eantis (sicklewings) can be recognized by their namesake sickle-shaped hindwing markings. The tribe's are more robust and colorful than the related Carcharodini and Erynnini.

Phylogenetic history
Formerly classified within a broadly defined Pyrgini containing numerous . Reorganization of Pyrginae to achieve monophyletic tribes resulted in recognition of Achlyodidini as distinct, though it is the closest relative to Pyrgini sensu stricto. The four-way split of Pyrgini sensu lato (into Pyrgini, Achlyodidini, Carcharodini, and Erynnini) better represents evolutionary diversity than the previous lumped classification.
Notable genera
Eantis (sicklewings) is the most commonly referenced due to its distinctive and widespread recognition. Eburuncus was described as recently as 2012 by Grishin, indicating ongoing taxonomic work in the tribe.
