Summary: A new species of podocerid amphipod, Podocerus setouchiensis sp. nov., was discovered on Etajima Island in the Seto Inland Sea, Japan. This species is distinguished from its relatives by the structure of its dorsal carination, antenna, gnathopods, uropods, and telson. The researchers provided nucleotide sequence data of the mitochondrial cytochrome c subunit I (COI) from a paratype of this species for future molecular systematic studies.

Summary: In this study, seven new Clonostachys species were found and identified through sampling in China, Vietnam, and Thailand, and two of them were described and illustrated based on morphological characteristics and molecular data. The phylogenetic positions of the seven species were evaluated using sequence data from four genomic loci (ITS, nrLSU, TUB2, and TEF1), and the genetic divergence of Clonostachys species for three markers (ITS, TUB2, and TEF1) were also compared. The results showed that TEF1 sequence data provided the best resolution for distinguishing Clonostachys species, followed by TUB2 and ITS regions.

Summary: During the investigation near Oimur, Kabansky District, sixteen species from the genus Gomphonema were discovered, with eleven previously described and five new to science. Ecological information about these Gomphonema species is provided, including their distribution within and outside Lake Baikal. The diversity of morphologies among Gomphonema species in Lake Baikal suggests in-lake speciation and the introduction of different species groups, supporting the idea of high endemism based on niche partitioning by depth.

Summary: The pollen morphology of the genus Sabulina from Turkey was studied to describe its characteristics and assess its diagnostic value for taxonomic implications. The pollen grains of Sabulina are radially symmetrical, apolar, rarely isopolar, and pantopolyporate with 8-28 pores. Numerical analysis revealed that pollen sizes, pore diameters, pore numbers, distance between pores, spinule density, and punctum numbers are particularly the most useful variables for separating the Sabulina taxa.

Summary: This study describes a symbiotic relationship between conulariids and holdfast producers, based on attachment scars on the conulariid test. The attachment scars offer insights into the paleoecology of this Silurian benthic assemblage, and statistical analyses suggest a possible commensal relationship between the two organisms.

Summary: This paper revises the genus Aberlemnia from the Early Devonian of Scotland based on its type-material A. caledonica and describes a new species, Aberlemnia krizii sp. nov, from the Silurian of Czechia. The study provides detailed diagnoses and highlights the differences between the two species. Aberlemnia is positioned on an evolutionary clade line leading to the Lycophytina.

Summary: In this study, an integrative approach (morphology based, ootaxonomy and molecular data) was used to investigate the species delimitation of the genus Afronurus in Thailand. Four species were identified and the subimago of A. gilliesiana was described for the first time. The egg chorionic structure of all four species was also described for the first time. The results strongly support the species delimitation based on morphological and molecular data.

Summary: Three new wood-inhabiting fungi species, Hyphoderma crystallinum, H. membranaceum, and H. microporoides, have been proposed based on a combination of morphological features and molecular evidence. Phylogenetic analyses showed their relationships within the Hyphoderma genus, demonstrating their distinct characteristics and evolutionary connections. Additionally, a map of global distribution for Hyphoderma species and an identification key for Chinese Hyphoderma are provided in this study.

Summary: Molecular studies suggest that jawed vertebrates originated no later than the Late Ordovician period. Newly discovered fossils from the early Silurian provide important insights into the early diversification of jawed vertebrates.

Summary: Geastrum belongs to the Basidiomycota, Agaricomycetes, Geastrales, and Geastraceae. The exoperidium of the genus Geastrum typically splits into a star-like structure when mature. It is a saprophytic fungus with significant research importance. Based on morphological observation and phylogenetic analysis of ITS and LSU, this study describes seven new species of Geastrum belonging to four sections: Geastrum laneum in Sect. Myceliostroma, Geastrum litchi and Geastrum mongolicum in Sect. Exareolata, Geastrum pseudosaccatum, Geastrum melanorhynchum, and Geastrum oxysepalum in Sect. Corollina, and Geastrum microphole in Sect. Campestria. Illustrated descriptions and ecological habits of these novel species are provided.

Summary: Tweedieia crabs, known for their ornate arrangement of granules and setae and eye-catching color pattern, are among the most beautiful decapod cryptofauna in Indo-West Pacific coral reefs. After revising the genus, it is now recognized that there are only two species: Tweedieia odhneri and T. laysani.

Summary: There are more wild cockroaches than household species, and they have a similar lifestyle of feeding on dead organic material and hiding in confined spaces. A unique fossil cockroach was discovered and initially thought to be a predator, but this hypothesis is uncertain. The study provides a redescription of the fossil cockroach and proposes a new closely related species. The discussion suggests that these species may feed on flowers instead of hunting for prey.
