The group is characterized by specific genitalic and wing venation features that distinguish it from related tribes.

Identification

Thymelicini skippers can be distinguished from related Hesperiinae tribes by a combination of genitalic characters, particularly in the male valvae structure, and specific wing venation patterns. The forewing typically lacks the pronounced hook or costal fold found in some other skipper tribes. Antennal clubs are relatively slender with hooked tips, as is common in Hesperiidae, but the overall body proportions tend to be more gracile than in the related Taractrocerini.
