Taxonomic Discussion:— Pabstiella garayi is a rare species, apparently endemic to the Serra do Castelo in Espírito Santo. In the original publication, Pabst described the lip as having a long, verrucose claw and an obtuse apex. Luer & Toscano (2011) later described Pabstiella discors from a collection in the same area of Espírito Santo, also noting a lip with similar morphology. However, they did not compare the new species to any other species in the genus.

A comparison of the original drawings of P. discors and P. garayi reveals that they are conspecific, as both illustrations show the lip as long-unguiculate with an obtuse apex, matching Pabst’s description. Nevertheless, a revision of the type specimens of both species and flower dissections from a cultivated plant collected in the same locality, indicates that the position of the lip was misinterpreted in both Pabst’s and Luer’s publications. In fact, the lip is 3-lobed, truncate at the base, with an elongate apical lobe and a central verrucose callus.
