Popis:	Phylogenetic relationships for a large number of Brazilian species of Pleurothallis sensi lato ( Acianthera , Anathallis , Pabstiella and Specklinia ) were inferred in an analysis of ITS nrDNA using both parsimony and Bayesian methods. Our results show that: 1) most Brazilian Pleurothallis species recently transferred into Stelis in fact belong to the genus Pabstiella ; 2) groups of species previously generally considered to be part of the genus Specklinia belong to Pabstiella ; 3) some infrageneric groups—mostly compatible with Luer's sectional organization of his Pleurothallis subgenus Acianthera— are clearly supported within Acianthera ; and 4) two species could represent a new genus.
