Hitherto this new species is recorded from the type locality only. According to the collector, the Amazonian orchid specialist Joa˜o Batista Fernandes da Silva, to whom the new species is dedicated, F. batistana was found as a saxicolous plant at a very humid site, near Curua´-una waterfall, in the middle of the Amazon forest. The collection site is about 400 km from the city of Santare´m, which is situated in the confluence of Tapajo´s and Amazonas rivers, not far from the border of the State of Amazonas. Since this site is far away from any other known localities of Fosterella, this finding changes the distribution range of the whole genus, which is characterized by an interesting disjunction (FIGURE 2): The main range of Fosterella is located in Central South America with a diversity center in the Bolivian Andes and several species recorded in both the Argentinian and Peruvian Andes, as well as in the tropical to subtropical lowlands of Bolivia and adjacent areas of Brazil and Paraguay. Only one species is recorded from Central America and Mexico: F. micrantha (Smith & Downs 1974, Smith & Read 1992, Ibisch et al. 1999, 2002; Espejo et al. 2004). —SeePeters 2009
