As an example, Keraudren (1958) formerly recognized 9 species of Melanophylla.  In our revision (Schatz et al. 1998), new collections allowed us to reevaluate the validity of several species that were originally known only from a single collection, as well as to reconsider the limits of variability of all species.  As a result, we merged, and therefore expanded, the concepts of several species within the genus.  In addition, we described a new species with unique features, which was first collected only in 1986.
