[3] The Nemeobiinae was erected to encompass the entirety of the 7 percent of Riodinids that reside within the Old World.

This has remained true, however, recent studies have placed the New World subfamily of Euselasiinae within the Nemeobiinae, with Corrachia and Styx believed to be apomorphic Nemeobiines.

[3] The greater Riodinid family is believed to have evolved in the Neotropics and migrated to the Old World through the Bering land bridge during the Oligocene.

[3] A single member of the subfamily exists on the continent of Australia, Praetaxila segecia.

[3] Seraphim et al. (2018) proposes through genetic analysis that the subfamily is split into two tribes, and the family would encompass members of the New World subfamily Euselasiinae as tribe Euselasiini within the Nemeobiinae, while Corrachia and Styx would be moved to the Nemeobiina.
