Taxonomic Note
The Doyenellus was established by Triplehorn in 1978, with previously assigned to related genera. The name honors American coleopterist John T. Doyen. The tribe Cteniopodini has undergone significant taxonomic revision, and the precise boundaries of Doyenellus relative to genera such as Cteniopus and Statira remain subjects of ongoing study.
