The following is a list of Eulophia species recognised by Plants of the World Online as of December 2023[update]:[1] A molecular phylogenetic study published in 2014 suggested the genus Eulophia was paraphyletic unless a clade containing Orthochilus was recognized and 34 species and one subspecies were transferred to the resurrected genus Orthochilus, which included many Eulophia and all Pteroglossaspis taxa.
[2] As of December 2023[update], the transfer was not recognized by Plants of the World Online and other sources.
The species transferred in the 2014 study are listed below,[2] with their names in Eulophia.
