“…In this section, we discuss the nomenclatural changes needed to redefine the Lepanthes clade as proposed by Bogarín et al . 23 as well as the relationships among these genera based on the phylogenetic insights and morphological evolution of key characters as presented in this study. The Lepanthes clade comprises four main subclades (clades 7, 9, 12 and 14 as shown in Fig.…”

“…Trichosalpinx as previously circumscribed 15,30 is confirmed as polyphyletic, and therefore re-circumscribed. The species belonging to Pendusalpinx and Tubella are confirmed to be unrelated to Trichosalpinx and therefore excluded, whereas Gravendeelia , Opilionanthe , Pseudolepanthes and Stellamaris are placed for the first time in a phylogenetic framework and recognized as distinct 23 . The polyphyly of Trichosalpinx was suggested in previous studies but the newly proposed genera were not evaluated or the sampling was too incomplete to allow a redefinition of these groups 11 .…”

“…Moreover, four generic concepts needed to maintain monophyly, were recently erected by Bogarín et al . 23 : Gravendeelia Bogarín & Karremans (1), Pendusalpinx Karremans & Mel.Fernández (seven), Stellamaris Mel.Fernández & Bogarín (one), and Opilionanthe Karremans & Bogarín (one) as well as the reinstatement of Pseudolepanthes (Luer) Archila (10) and Tubella (Luer) Archila (79). The species largest genus is Lepanthes , which comprises more than 77% of the species of the clade.

“…To achieve this, we evaluate the relationships among members of the Lepanthes clade by assessing morphological characters within a phylogenetic framework. We performed ASRs on 18 floral morphological characters using a well-resolved phylogenetic inference from nuclear nrITS and plastid matK markers of 122 species covering all recognized genera within the clade 23 . We want to answer the following questions: (1) which monophyletic genera can be recognized based on a phylogenetic framework?…”

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.
