This tribe was initially categorized by John Lindley in 1840.
Its largest subtribes are Arethusinae and Coelogyninae.
Bletiinae was once considered a subtribe of Arethuseae, but it was moved to Epidendreae in 2005.
[2] Sobraliinae has been considered a subtribe of Arethuseae, but is now recognized at the rank of tribe within the subfamily Epidendroideae.
