Towards integrative taxonomy in Neotropical botany: Disentangling the Pagamea guianensis species complex (Rubiaceae)

Species complexes are common in the Neotropical flora, and the Pagamea guianensis complex is one of the most widespread groups of species in the Amazonian white-sand flora. Previous analyses suggested the occurrence of ten species in this group, but species limits remained unclear due to poor sampli...

Previous analyses suggested the occurrence of ten species in this group, but species limits remained unclear due to poor sampling, morphological overlap and low molecular variation. Here we present the most comprehensive population and molecular sampling across the geographical distribution of the P. guianensis complex to date in order to test the monophyly of this group and to clarify species limits. Using a high-throughput DNA sequencing approach, we sequenced 431 loci (> 34 M bases) for 179 individuals. We applied phylogenetic and species tree analyses to resolve phylogenetic relationships among the sampled individuals. Species delimitation was inferred based on genomic data, and we tested whether hypothesized species could be differentiated using morphological, ecological and near-infrared spectroscopy data. We confirm the monophyly of the P. guianensis complex and accept 15 distinct and well-supported lineages, here proposed as 14 species and one subspecies. Our findings highlight the importance of multiple lines of evidence from independent datasets in the process of species delimitation and species discovery in species complexes in the Neotropics. © The Botanical Journal of the Linnean Society 2018. 2020-05-18T14:33:53Z 2020-05-18T14:33:53Z 2018 Artigo https://repositorio.inpa.gov.br/handle/1/15689 10.1093/botlinnean/boy051 en Volume 188, Número 2, Pags. 213-231 Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Botanical Journal of the Linnean Society
