dc.description.abstract | Taxonomic delimitations are challenging because of the convergent and variable nature of phenotypic
traits. This is evident in species-rich lineages, where the ancestral and derived states and their gains
and losses are difficult to assess. Phylogenetic comparative methods help to evaluate the convergent
evolution of a given morphological character, thus enabling the discovery of traits useful for
classifications. In this study, we investigate the evolution of selected traits to test for their suitability
for generic delimitations in the clade Lepanthes, one of the Neotropical species-richest groups. We
evaluated every generic name proposed in the Lepanthes clade producing densely sampled phylogenies
with Maximum Parsimony, Maximum Likelihood, and Bayesian approaches. Using Ancestral State
Reconstructions, we then assessed 18 phenotypic characters that have been traditionally employed to
diagnose genera. We propose the recognition of 14 genera based on solid morphological delimitations.
Among the characters assessed, we identified 16 plesiomorphies, 12 homoplastic characters, and
seven synapomorphies, the latter of which are reproductive features mostly related to the pollination
by pseudocopulation and possibly correlated with rapid diversifications in Lepanthes. Furthermore,
the ancestral states of some reproductive characters suggest that these traits are associated with
pollination mechanisms alike promoting homoplasy. Our methodological approach enables the
discovery of useful traits for generic delimitations in the Lepanthes clade and offers various other
testable hypotheses on trait evolution for future research on Pleurothallidinae orchids because the
phenotypic variation of some characters evaluated here also occurs in other diverse genera. | |
