The Ctenuchina were previously classified as the subfamily Ctenuchinae of the family Arctiidae. That subfamily contained three tribes: Ctenuchini, Euchromiini (wasp moths), and Syntomini. The family Arctiidae was lowered in rank to the subfamily Arctiinae, and consequently, the three tribes became subtribes (with the -ina suffix). Ctenuchina and Euchromiina were reclassified in the tribe Arctiini, while the Syntomina were raised in rank to the tribe Syntomini.[1][2]
