Summary: Neoporphyra kitoi is a newly described species of red algae found in Honshu, Japan. It is distinguished from other similar species by both molecular and developmental characteristics, with the unique feature of new blades arising from rhizoidal cells. Molecular phylogenetic analysis places Neoporphyra kitoi in a clade containing sequences of the genus Neoporphyra.

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: 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.

Summary: A new seaweed, Pseudobangia corderoi, previously misidentified as Bangia fuscopurpurea, was described from the Philippines. Molecular analysis showed that P. corderoi is closely related to an unidentified Pseudobangia species from Taiwan, and they are the closest relatives to Pseudobangia kaycoleae. Phylogenetic studies also confirmed the monophyly of Pseudobangia and its sister relationship with the 'Bangia 2' lineage. Morpho-anatomical analysis only found one distinguishing character, larger thallus dimensions, for P. corderoi compared to other filamentous Bangiales.

Summary: A new species of Fredericqia from the Choshi Peninsula, Japan has been described based on morphological and molecular analyses, with unique characteristics such as a flattened incurved thallus and marginal proliferations. Molecular analysis indicates that this new species, named Fredericqia chiharae, belongs to the genus Fredericqia and is distinct from other species within the genus.

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 describes two new species, Endoplura jejuensis and E. koreana, from Korea based on molecular and morphological analyses. Phylogenetic analysis shows that they are closely related to E. aurea from Japan. E. jejuensis is characterized by small light to dark brown thalli, while E. koreana has larger olive or yellowish-brown thalli.

Summary: A new red alga species, Dasya japonovillosa, is introduced from Japan. This species, as well as D. enomotoi, were previously misidentified as D. villosa by researchers in Japan due to their elongated axes densely covered with soft monosiphonous filaments. Dasya villosa can be distinguished from D. japonovillosa and D. enomotoi by the presence of five pericentral cells in transverse sections and palisade-like tetrasporangial cover cells. The unique characteristics of the new species include elongated axis (up to 65 cm), subdichotomously divided axes and polysiphonous branches, indistinct pericentral cells in transverse sections except near the apices, enlarged inner cortical cells, radially arranged numerous soft monosiphonous filaments, three-celled carpogonial branches, four tetrasporangia in each fertile segment of the stichidia, and one (rarely two) tetrasporangial cover cell that is not elongated longitudinally and rarely divided transversely.

Summary: This study used DNA sequences and morphological observations to confirm that Cystoclonium obtusangulum actually consists of two distinct species, leading to the proposal of a new genus name Meridionella. These two species are morphologically similar but have different distributions, one found in South America and the Falkland Islands, and the other occurring in Antarctic waters.

Summary: Colpomenia borea sp. nov. was described based on morphological observations and molecular analyses using mitochondrial cox3 and chloroplast rbcL genes. It is distinguished from other Colpomenia species by its small globular to ovoidal thallus and thin thallus membrane. C. borea is epiphytic on the brown alga Stephanocystis in protected areas. The phylogenetic analysis showed that C. borea is a distinct species, closely related to C. peregrina.

Summary: This study identified genetically differentiated groups within Gelidiella acerosa using genetic sequence data, and classified the Atlantic group as an independent species of the cryptic complex. Gelidiella papillosa sp. nov. is supported only by its genetic independence and allopatric distribution.

Summary: To resolve the uncertainty around taxonomic classification of Sporolithon species, targeted PCR sequencing was conducted on historical and recently collected specimens. The results confirmed the existence of distinct species and identified previously misclassified specimens. DNA sequencing of type specimens of coralline species was shown to be the most reliable method for accurate naming.
