The Ctenuchina were previously classified as the Ctenuchinae subfamily of the Arctiidae family. That subfamily contained three tribes: Ctenuchini, Euchromiini (wasp moths), and Syntomiini. The Arctiidae family was lowered in rank to the Arctiinae subfamily, and consequently, the three tribes became subtribes (with the -ina suffix). Ctenuchina and Euchromiina were reclassified in the Arctiini tribe, while the Syntomiina were raised in rank to the Syntomiini tribe.
