Abstract

A new species of Anathallis, A. roseopapillosa, is described from the central Brazilian Amazon. It is morphologically related to A. gracilenta, but differs by having shorter racemes arising abaxially from the leaves, with flowers opening one at a time, petals with a papillose apex, and an oblong-elliptic to ovate-elliptic lip, which is often obscurely tri-lobed. We also provide evidence of the phylogenetic position of the new species in the subtribe Pleurothallidinae by means of a cladistic analysis of nuclear DNA sequence data (ITS).
