Only Eulia is found in the Old World, since it has a Holarctic distribution.

The tribe was first proposed as Euliae by Kuznetsov and Stekolnikov (1977) as a subtribe of Cochylini.

Powell elevated the group to tribal status in 1986.

Research by Regier et al. in 2012 has provided fairly convincing evidence that Cochylini are a monophyletic lineage within a broader Euliini.

If this is accepted, Cochylini should be treated as subtribe Cochylina of Euliini.
