≡ Pleurothallis ezechiasi Hoehne (1946: 21) .

Type: — BRAZIL. Minas Gerais: Coronel Pacheco, lados do Rio Doce , 28 June 1945, E.P. Heringuer 1939 (holotype: SP 48447 !).

= Pabstiella naimekei Chiron & Ximenes Bolsanello (2012: 113) , syn. nov.

Type: — BRAZIL. Espírito Santo: Santa Maria de Jetibá, Pedra do Garrafão , 1400 m, 2012, A. Naimeke s.n & G. Chiron 12083 ( MBML 47112 !).

Taxonomic Discussion:— Pabstiella ezechiasi was first collected in 1946 near the Doce River in eastern Minas Gerais, within an area of the Atlantic Rainforest that has undergone significant disturbance. Since then, no further collections of this species have been recorded again from Minas Gerais. A specimen collected by R. Kautsky in Domingos Martins, Espírito Santo, and deposited at HB (63537!), indicates that the species also occurs in the Serra do Castelo. The holotype of Pabstiella naimekei was collected in Santa Maria de Jetibá, a municipality adjacent to Domingos Martins, within the Serra do Castelo.

A comparison of these two entities clearly indicates they represent the same species: a small plant with short ramicauls, elliptical to obovate, coriaceous leaves, and inflorescences longer than leaves, bearing up to nine orange to yellow flowers. The sepals are puberulent internally, the lip is orange to vinaceous, and the column is winged.
