Otostylis brachystalix (Rchb.f.) Schltr. 1918][type désigné par K. Senghas & G. Gerlach in F.G. Brieger et al. (Eds.) Die Orchideen I/B, 27. 3 ed, 1698. 1993] (Brésil, Amazonas, leg. G. Wallis).
D'après T.E.C. Meneguzzo

22. 09/12/2015: "Alrich & Higgins (2011) stated that Pupulin et al. (2009b: 515) selected
Zygopetalum brachystalix as the type of the genus. However, it cannot be considered an effective typification because it was not made in an explicit way (McNeill et al. 2012: art. 7.10), and the type designation was only made in a definitive manner by Senghas & Gerlach (1993)."
