Taxonomie : D'après Vale et al. (Syst. Bot., 37(4): 883-892. 2012): "With more than 10 species, Tetramicra Lindley is an orchid genus endemic to the Caribbean islands, among which Hispaniola and Cuba have the majority of the species (Whitner 1996; Nir 2000; Ackerman in press). Recent phylogenetic molecular analyses nested the genus within the Broughtonia alliance, which consists of the genera Broughtonia, Psychilis, Quisqueya, and Tetramicra (van den Berg et al. 2000; Higgins et al. 2003; van den Berg et al. 2009), and is one of the few groups of plants entirely evolved in the Greater Antilles (Francisco-Ortega et al. 2009)."
