Summary: Recent segregation of 12 genera in the tribe Streblocladieae has updated the taxonomy of certain species belonging to Polysiphonia sensu lato, with new combinations being proposed. Six new additions to the tribe have been made based on morphological and molecular analyses, including the description of a new species and proposal of new combinations. The study also identified additional diagnostic features for two genera within the tribe, providing insights into distribution, diagnostic features for delimiting genera morphologically, and molecular evolutionary relationships.

Summary: This study reveals a new species, G. khanjanapajiae, in Thailand through morphological and genetic analyses. The species can be distinguished by its dentate blade margin, deep spermatangial conceptacles, and abundant nutritive filaments. Phylogenetically, it is closely related to G. spinulosa from Taiwan. The research highlights the ongoing discovery of Gracilaria diversity and distribution in the tropical Indo-Pacific.

Summary: The study identified a deep-water species of Rhodymenia prostrata as a new species in the genus Halopeltis, which was named Halopeltis tanakae. This new species, characterized by specific anatomical features, was found in the northwestern Pacific and represents the second species of the genus in the region.

Summary: The Peyssonneliaceae is the only family in the order Peyssonneliales, encompassing widespread red encrusting algae. Through molecular phylogenies and morphological analyses, a revised taxonomic scheme for the Peyssonneliales has been proposed, uncovering underestimated diversity in Brazilian red algae.

Summary: The bladed Bangiales collected from Shikinejima Island and Hachijojima Island in southern central Japan were identified as Neoporphyra haitanensis based on morphological and molecular analyses, showing significant similarities to the cultivated species in southern China. This study represents the first record of N. haitanensis in natural populations in Japan.

Summary: Molecular sequence analyses revealed that specimens previously identified as Cirrulicarpus sp. in southeastern Brazil are actually more closely related to the genus Meredithia. A new species, Meredithia dichotoma, is proposed to accommodate this rare and endemic taxon. It is characterized by its unique morphology and sequence divergence from its congeners. This finding represents the first record of a Meredithia species in Brazil and in the western South Atlantic, contributing to the diversity of the red algal family Kallymeniaceae.

Summary: A multigene molecular phylogeny was conducted to study the genus Phymatolithon. The study revealed the polyphyletic grouping of two monophyletic clades within the Hapalidiales. As a result, a new genus, Phymatolithopsis, was established, consisting of three species. Phymatolithopsis is closely related to Mesophyllum and is distinct from Phymatolithon and boreal species assigned to Lithothamnion. Morpho-anatomical characteristics were used to differentiate Phymatolithopsis from Phymatolithon, including the origin of conceptacle primordia and the distribution of gonimoblast filaments in carposporangial conceptacles.

Summary: A new species, Fragilaria shirshovii sp. nov., was identified and described based on molecular and morphological investigations. The species was isolated from desalinated water masses in the Gulf of Ob, where river and marine waters mix. The study analyzed the morphology of the species using light microscopy and scanning electron microscopy. The importance rating for this article is 8 out of 10.
