“…Laurenciella When the new genus Laurenciella was described, L. marilzae was reported both in Brazil and in the Canary Islands. In 2014, the species was also reported in Mexico and in many islands of Macaronesia (Machín-Sánchez et al 2014). Here, we further extend the distribution of the genus to the Mediterranean Sea; however, we question whether this new record is conspecific with L. marilzae as it falls in the grey zone between intra-and interspecific divergence (0.5% of divergence in rbcL).…”

D N A L i b r a r y o f L i f e , r e s e a r c h a r t i c l eAbstract. The systematics of the Laurencia complex was investigated using a taxon-rich data set including the chloroplast ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL) gene only and a character-rich data set combining mitochondrial cytochrome oxidase 1 (COI-5P), the rbcL marker, and the nuclear large subunit of the ribosomal operon (LSU). Bayesian and ML analyses of these data sets showed that three species hitherto placed in the genus Laurencia J.

“…DNA barcodes in conjunction with morphological, biochemical, and ecological information are revealing an outstanding diversity of species previously unrecognized through the analysis of morphological variation alone. During the first 8 months of 2014, the Web of Science recorded 310 publications in which DNA barcoding was used in discovering and describing new species, including algae [78], ferns [79], fungi [80], nematodes [81,82], arthropods [83,84], mollusks [85], fish [25], birds [86], and mammals [87]. Early on, it was expected that a single genetic marker would serve as a universal DNA barcode to identify species across the eukaryotic Tree of Life.…”

“…DNA barcoding has proved to be an effective taxonomic tool to identify, and analyze species diversity within the Laurencia complex (Machín‐Sánchez et al. ), substantiating identifications based on morphological characters. Following our previous studies on the diversity of the Laurencia complex in the Macaronesia region (Machín‐Sánchez et al.…”

Species diversity within the genus Osmundea in the Macaronesian region was explored by conducting a comprehensive sampling in the Azores, the Canary, and the Madeira archipelagos. Toward identification, all specimens were first observed alive to verify the absence of corps en cerise, a diagnostic character for the genus and morphometric data were measured (thallus length and width, first-order branches length and width, branchlets length and width, cortical cell length and width in surface view, cortical cell length and width in transverse section). Specimens were sequenced for COI-5P (39 specimens) and three species delimitation methods (Generalized Mixed Yule Coalescent, Automatic Barcode Gap Discovery method, and Poisson Tree Processes) were used to assess the threshold between infra- and interspecific relationships. Subsequently, one or several sequences of plastid-encoded large subunit of RuBisCO (21 specimens) per delimited species were generated to assess the phylogenetic relationships among Macaronesian Osmundea. Moreover, for each delineated species, vegetative and reproductive anatomy was thoroughly documented and, when possible, specimens were either assigned to existing taxa or described as novel species. This integrative approach has provided data for (i) the presence of O. oederi, O. pinnatifida, and O. truncata in Macaronesia; (ii) the proposal of two novel species, O. prudhommevanreinei sp. nov. and O. silvae sp. nov.; and (iii) evidence of an additional species referred as "Osmundea sp.1," which is a sister taxon of O. hybrida.
