Abstract
We investigated fresh collections and an isotype of Phyllophora peruviana from central Peru using morphology and sequencing the plastid rbcL gene. In the rbcL phylogenetic tree, P. peruviana consisted of three genetic groups, forming a clade. As this P. peruviana clade was distantly related to Phyllophora including the generitype Phyllophora crispa and also distinct from other genera in the Phyllophoraceae, we describe Phyllophorella peruviana gen. et comb. nov. and two new species, Phyllophorella humboldtiana sp. nov. and Phyllophorella limaensis sp. nov. The genus Phyllophorella is distinguished from Phyllophora by a compressed stipe rather than a terete stipe, and tetrasporangia in nemathecia rather than sori scattered over the thallus surface. Phyllophorellahumboldtiana sp. nov. is characterized by broad blades with slightly lobate margins. Phyllophorella limaensis sp. nov. is recognized by its small, ligulate blades. Phyllophorella peruviana is distinguished by dichotomo-flabellate blades that arise from a short compressed stipe. All three species of Phyllophorella are currently known only from Peru but may be more widely distributed.
About the authors
Martha S. Calderon earned her PhD in Biodiversity and Environmental Ecology from Chungnam National University, Korea in 2016 for her work on the systematics and phylogeography of the family Phyllophoraceae (Gigartinales, Rhodophyta). Her research interest focuses on phylogeography, evolution, and diversity of marine algae, using bioinformatics and phylogenetics to answer specific questions about their evolutionary history.
Sung Min Boo is a professor teaching Botanical Systematics at Department of Biological Sciences, Chungnam National University. He was awarded a PhD by Seoul National University for the taxonomy of the family Ceramiaceae. His research includes the diversity and distribution of brown and red algae.
Acknowledgments
We thank Martha S. Rios for collecting specimens in Peru and Kathy Ann Miller for providing a fragment of the isotype of Phyllophora peruviana. This work was supported by Marine Biotechnology grants from the Korean government’s Ministry of Oceans and Fisheries to SMB. We appreciate Matt Dring, the Editor-in-Chief, and two referees for improving the manuscript during the review process.
