Summary: This study conducted molecular, genetic, and morphological analyses of Lomentariaceae, resulting in the discovery of a new species, Ceratodictyon sanctae-crucis sp. nov., and the proposal of a new genus, Yendoa gen. nov., within Lomentariaceae. The study also revealed that Lomentariaceae now consists only of monophyletic genera, providing a more coherent taxonomic framework for the family.

Summary: DNA sequence analysis reveals that the current classification of Gelidium is not monophyletic, with three distinctive lineages. A new genus, Gelidiorariphycus, is described to accommodate one of these lineages. The species in this genus have similar morphologies and primarily grow on shallow subtidal rocky shores.

Summary: Three new species of the red algal genus Asteromenia were described in this study, with one being a previously misidentified undescribed species and the other two from different islands. These new species showed morphological overlap and required accurate species recognition through DNA sequencing. The study highlights the importance of sequence analysis.

Summary: This study aims to understand the phylogeny and diversity of Gracilariaceae in Chinese waters by constructing a DNA sequence database. Through the analysis of rbcL and COI-5P genes, 19 Gracilaria and 3 Gracilariopsis species were identified, including a new diminutive species Gracilaria tsengii sp. nov. and a new record species G. perplexa.

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: This study utilized morpho-anatomy and DNA sequence analysis to identify a species of nongeniculate coralline algae, and discovered two new species. The research also revealed that the identified species currently inhabits mesophotic rhodolith beds in the northwestern Gulf of Mexico and other Caribbean regions.

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 evaluated the efficiency of four genetic markers in barcoding diatoms isolated from China, showing that multiple genetic markers can clearly differentiate most species and reveal potential cryptic species. COI, rbcL, and LSU sequences demonstrated high taxonomic resolution at the species level, while potential identification errors were found in public diatom sequences. Phylogenetic and character-based analysis provided consistent species identification and clearer species discrimination compared to the distance-based method.

Summary: A new species of the globally distributed red macroalgal genus Caloglossa, Caloglossa fonticola sp. nov., was described and illustrated from an underground spring in Bama County, Guangxi, China. This new species is morphologically distinguishable from other species in the genus and expands the known diversity of Caloglossa.

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: This study used morphological and molecular phylogenetics methods to study turf-forming species of the genus Pterocladiella in southern China. A new species and a previously unrecorded species were identified, and additional descriptions of reproductive structures were provided for two other species. This study enhances our understanding of the biodiversity of Pterocladiella in China and reveals the potential diversity of small turf-forming species in tropical coral reefs.

Summary: We analyzed sequence data of rbcL and COI in Schizymenia specimens from the Sea of Okhotsk and Sea of Japan. A new species, S. tamarae sp. nov., was discovered in the northwestern Sea of Japan. Morphological and genetic analyses confirmed that the previously described S. jonssonii is a synonym of S. dubyi var. palmata, which was originally described from the Kuril Islands. The taxon was synonymized with Neoabbottiella valentinae. We propose renaming it as Schizymenia valentinae comb. nov. The known Schizymenia species along the Russian coast are S. valentinae and S. tamarae.
