Naturally occurring species of this subtribe are among the more popular orchids of horticulturalists, especially the genera Dracula, Dryadella, Masdevallia and Restrepia.

The following genera are considered monophyletic : Barbosella (including Barbrodia), Dracula, Dresslerella, Dryadella, Lepanthes, Masdevallia, Platystele, Porroglossum, Restrepia, Scaphosepalum, Trisetella, and Zootrophion.

Many genera in the Pleurothallidinae were found polyphyletic, for example species attributed to the genus Pleurothallis are scattered across five clades.
