Summary: This study focuses on the tribe Nitelleae of family Characeae in the Northern Territory. A total of 16 Nitella species are identified in this region, including seven previously described species and nine newly described species. Among them, N. belangeri and N. tumulosa are newly recorded for the Australian flora. Other previously reported Nitella species were either misidentified or had inaccurate localities. Morphological characteristics and reproductive arrangements are used to differentiate all the Nitella species, and keys, illustrations, and descriptions are provided.

Summary: The taxonomic status of five European Tolypella taxa was investigated using gene sequence data and morphological characteristics. The results showed inconsistencies between morphological and genetic identification, suggesting the need for further examination of the taxonomy of Tolypella sect. Tolypella.

Summary: This study investigates three new Amphileptus species discovered in northern China using standard alpha-taxonomic methods. Phylogenetic analysis of nuclear small subunit ribosomal DNA (SSU rDNA) sequences suggests that the family Amphileptidae might be monophyletic while the genus Amphileptus is paraphyletic, with multiple well-delimited species groups.

Summary: The study found that light and temperature are key factors influencing the production and growth of Chara aspera, and there are differences in production levels at different scales, indicating the importance of shelf-shading and below-ground processes in natural plant assemblages.

Summary: A new species of Sporoxeia, named S. vietnamensis, is described in this article. It is similar to S. blastifolia in morphology, but can be distinguished by characteristics such as leaf blades, hypanthia, calyx lobes, and petals. Detailed information including photos, illustrations, habitat, ecology, and conservation assessment are provided, along with an identification key to the Sporoxeia species.

Summary: A new genus and thirteen species of jumping spiders from northern Vietnam are described. The new genus, Zabka gen. nov., accommodates two transferred species from Euophrys Blackwall,1841, including the generotype, Z. cooki (Zabka, 1985), comb. nov., and Z. xuyei (Lin & Li, 2020), comb. nov. Additionally, twelve new species are described, along with diagnostic photos of the habitus and copulatory organs.

Summary: Diablophthalmus, a new genus, is described based on two new species, D. wygodzinskyorum sp. n. and D. marmoratus sp. n., found in P??ramo habitats in Colombia. These insects are the first recorded members of the Megophthalmini tribe from South America. The article discusses their morphological convergent features shared with other soil-dwelling Membracoidea.

Summary: A new species of hornshark, Heterodontus marshallae n. sp., has been identified in northwestern Australia. It was previously thought to be the same species as H. zebra from the Western Pacific, but genetic and morphological differences, as well as differences in egg case morphology and coloration, have confirmed it as a distinct species. The H. marshallae n. sp. is endemic to northwestern Australia and inhabits deeper waters than H. zebra.

Summary: Through morphological, ecological, and distributional analysis, it was discovered that Chara denudata from South Africa and C. dissoluta from Central Europe, originally believed to be the same species, are in fact distinct species. The presence of different traits and their distinct biology, habitat preference, and distribution confirms that the 'unfinished' morphogenesis in charophytes can hide different speciation pathways.

Summary: Parglogenia cobourgensis, a new species of camaenid land snail, was discovered in Cobourg Peninsula, Northern Territory, Australia. Despite having an identical shell to Parglogenia pelodes, these two species differ significantly in reproductive anatomy and mitochondrial phylogenetics. Another potential species was hypothesized based on limited specimens from Croker Island, West Arnhem Land, but further study is needed before formal naming.

Summary: In this study, Sarcocheilichthys sciistius was confirmed as a valid species based on morphological and molecular systematic studies. Additionally, S. czerskii and S. soldatovi were found to be synonyms of S. sciistius. The distinguishing features of S. sciistius from S. nigripinnis include more lateral-line scales, shorter lower lip, and differences in the coloration of pectoral and pelvic fins. The phylogenetic trees based on the Cyt b gene also supported the separation of S. sciistius as a distinct species.

Summary: Strobilanthes spathulatibracteata, a new species discovered in northern Vietnam, is morphologically similar to S. tonkinensis but differs in several characteristics. These include its perennial undershrub habit, hirsute young stem, fragrant stem and blades, spathulate bracts and bracteoles, 2-lipped calyx, puberulent outside and hir-sute inside corolla measuring 35-45 mm long, and apically pubescent fruits. The article provides photographs, illustrations, habitat information, ecological details, pollen morphology, and a preliminary conservation assessment.

Summary: Comprehensive charophyte surveys on the island of Sardinia, Italy have led to the discovery of a new species of Lamprothamnium. This new species, Lamprothamnium sardoum sp. nov., differs from other species in various characteristics such as the clustering of antheridia and oogonia, the presence of sterile whorls, and the persistence of the protonema on mature plants. The study also includes data on the hydrochemistry and accompanying flora of the Sardinian site, as well as proposals for management and conservation.
