“…Polymerase chain reaction (PCR) was carried out on the samples to amplify the DNA of two markers (for the primers see Appendix S1). We chose partial nrSSU and entire rbcL, which were the most common markers in previous studies to infer the phylogenetic relationships within the Bangiales (Oliveira et al 1995;Müller et al 1998;Nelson et al 2005;Broom et al 2010;Sutherland et al 2011;Deng et al 2015;Guillemin et al 2016;Abe et al 2021;Sano et al 2021). A total of 25.1 μL PCR reaction volume contained 20 units of Taq DNA Polymerase (in 20 μL GoTaq™ buffer containing 5 mM MgCl 2 , 1.25 mM dNTPs), 1.7 μL of each primer and 1.7 μL of template DNA.…”

A new filamentous marine red alga, Kuwaitiella rubra gen. et sp. nov. (Bangiales, Rhodophyta), is described from Kuwait in the north-western Arabian Gulf (also referred to as the Persian Gulf). It was found on a submerged fishing line. The intensively red upright thallus of up to 1 cm in length consists of cells containing a single stellate plastid. The thallus is initially uniseriate but becomes biseriate in its distal part upon transformation into globular reproductive cells, possibly archaeospores. The biseriate fertile part is the only morphological difference from other filamentous species of the Bangiales, in which this region is parenchymatous. In culture, bipolar asymmetric germination of the spores of Kuwaitiella led to a new generation of identical erect thalli, fixed to the substratum by colourless rhizoids. According to phylogenetic analyses of partial small subunit nuclear ribosomal DNA (18S) and of the plastid-encoded ribulose-1,-5-bisphosphate carboxylase/oxygenase large subunit (rbcL), the new species forms an additional lineage of the Bangiales, genetic similarity with other taxa being limited (maximum 91% in SSU and 90% in rbcL). It was no clear member of any known lineage of the Bangiales but was weakly associated with the filamentous species Minerva and Dione from New Zealand. In a SSU phylogeny, it formed a basal branch in the Bangiales and clustered with M. aenigmata and D. arcuata as sister clade to all other species of the order. In a rbcL phylogeny, it was part of a large polytomy of lineages, its closest relative being D. arcuata. Kuwaitiella forms the 8 th lineage of filamentous Bangiales detected so far.

“…In Japan, 29 species of bladed Bangiales are distributed as reported in Yoshida et al (2015). However, new species, cryptic species, and species newly recorded from Japan have been discovered in bladed Bangiales based on detailed morphological observations and molecular analysis, and further genetic diversity in Japan has also been revealed (Niwa et al 2014, Abe et al 2021, Sano et al 2021. Although previously reported from Japan by Sutherland et al (2011), Neoporphyra haitanensis was recently recorded from Shikinejima and Hachijojima, Izu Islands, Japan (Sano et al 2021), islands thought to be inhabited by N. dentata, a morphologically similar species (Okamura 1930, Segawa 1936, Takahashi et al 2015.…”

SUMMARYThe Izu Islands of southcentral Japan are thought to fall within the distribution range of Neoporphyra dentata. However, the gametophytic blades of Bangiales collected from Shikinejima and Hachijojima, Izu Islands, were identified as Neoporphyra haitanensis in our previous study. Thus, it became uncertain whether N. dentata is distributed in the Izu Islands, including Shikinejima. To clarify whether N. dentata grows on Shikinejima, we conducted a further distribution survey of N. dentata on the island. The morphological features of the blade samples collected from an additional sampling site on Shikinejima were more similar to those of N. dentata than to those of N. haitanensis: the blade thickness and the division formula of spermatangia resembled those of the former species rather than the latter species. However, the division formula of zygotosporangia was different from those of either species. The phylogenetic analyses of the rbcL gene indicated that the samples were resolved in a clade including N. dentata collected from Shirahama, Chiba Prefecture, and Enoshima, Kanagawa Prefecture, Honshu, Japan. The p‐distances of the chloroplast rbcL gene and nuclear 18S rRNA also supported identification of the samples as N. dentata. The results demonstrated that N. dentata is also distributed on Shikinejima with co‐occurring N. haitanensis, and that the island materials of the two species are genetically different from other materials of the two species, respectively.
