The monospecific genus Incaea was previously unplaced in the Pleurothallidinae . In the analyses presented here its type species is placed amongst members of Dryadella , rather than Pleurothallis or Phloeophila ( Chiron et al. 2016) . Morphologically D. yupanki is in fact similar to other species of this genus.

Species of Pleurothallis sect. Muscariae ( Luer 1986) , which later formed the genus Muscarella ( Luer 2006) , have been mostly accepted as part of Specklinia ( Pridgeon & Chase 2001, Pridgeon 2005). However, the genus forms a well-defined clade, which cannot be included within Specklinia . Species of Muscarella can be recognized by having a stem shorter than the leaves, inflorescences that are frequently lax-flexuous but can vary from elongate to fasciculate, always develop successively, and have one or rarely a few flowers open at the same time. Flowers are resupinate. Sepals are usually caudate, the petals fimbriate and acute to caudate. The column is elongate, without prominent wings or ornamentation. The pollinia are of the “whale-tail” type, with a dry, granulose, bilobate caudicle.

Muscarella as defined by Luer (2006) is accepted. It then included 48 species; six species are added here to bring the total number up to 54.
