Background: A continental-scale, georeferenced checklist of slime moulds (Eumycetozoa) for Central and Eastern Europe, supplemented with standardised environmental covariates and with a particular emphasis on forest ecosystems, has not previously been available. The absence of a harmonised corpus has constrained statistically supported tests of habitat- and substrate-related patterns and limited objective gap-mapping, particularly within forest ecosystems, where microclimatic buffering, dead-wood continuity and stand history are expected to be decisive; it has also hindered rigorous evaluation of slime moulds' role as bioindicators of forest habitat types, substrate associations and gradients in anthropogenic pressure (naturalness).

New information: Literature discovery spanned multidisciplinary and domain-specific platforms; inclusion required a determinable taxon, a locality at least to country level and a year. Records were de-duplicated conservatively; names were harmonised to a single authority (Eumycetozoa.com) with GBIF Species backbone as a fallback and higher taxonomy was filled consistently. The resource comprises presence-only occurrences, a taxonomically standardised checklist and a reference set; the curated bibliography comprises 528 bibliographic entries. Coverage spans Austria, Belarus, Czechia, Estonia, Germany, Hungary, Latvia, Liechtenstein, Lithuania, Moldova, Poland, Russia (European part), Slovakia, Slovenia, Switzerland and Ukraine. Event dates range from 1857 to 2025-08-01 and support ranges and mixed precision. Environmental content includes elevation, consolidated forest class, substrate category, habitat pressure, microhabitat, pH, air temperature, annual precipitation and stand age; controlled vocabularies comprise eight consolidated forest classes, ten substrate categories and seven habitat-pressure classes. The dataset is released under CC-BY-4.0 (Creative Commons Attribution 4.0 International), employs reproducible DwC mapping and stable identifier versioning and is suited to ecological and biogeographic analyses, including forest-focused modelling and gap analyses.

Background: The present work provides an inventory of the plant species recorded in two distinct coastal grassland vegetations: the Azores Archipelago (São Miguel Island) and the south-western coast of mainland Portugal (Sesimbra and Sines Regions - Setúbal District). Sites were selected in both regions to have a similar general substrate (rocky), latitude and elevation. Thirty-one sites were selected in the coastal grasslands: thirteen were located on São Miguel Island and eighteen on the mainland, distributed across Sesimbra (12) and Sines (6). All sites were visited once during the spring of 2022. In each site, 30 photos were taken at 5-metre intervals, for a total of 930 photos.The Sesimbra and Sines Regions were chosen because they represent well-preserved examples of coastal grassland vegetation on the south-western coast of mainland Portugal, sharing similar environmental characteristics with the coastal grasslands of São Miguel Island, such as rocky substrate, Atlantic exposure and comparable latitude. This design allows a meaningful comparison between insular and continental vegetation under similar abiotic conditions, providing a standardised framework for documenting coastal plant diversity across contrasting geographic contexts.

New information: Most records consolidate previously documented occurrences from national repositories, but here they are re-validated through standardised, plot-based, georeferenced surveys that harmonise taxonomy and metadata. Crucially, this release constitutes the first coordinated, standardised inventory of coastal grassland vascular plants spanning the Azores and the south-western mainland of Portugal, enabling direct cross-regional comparisons. In addition to several within-plot distributional updates, we document multiple introduced and invasive taxa, most notably Carpobrotus edulis and Oxalis pes-caprae, that are known to reshape coastal communities. As expected for Atlantic coastal grasslands, the flora is dominated by Asteraceae, Poaceae, Fabaceae and Brassicaceae, providing a baseline for long-term monitoring and management across both archipelagic and continental shores.

Continuing the international efforts of the ARMS Marine Biodiversity Observation Network (ARMS-MBON), we present data from the second sampling campaign, coming from 56 Autonomous Reef Monitoring Structures (ARMS) deployed in 2020 and 2021 along European coasts under the European Marine Omics Biodiversity Observation Network (EMO BON). The dataset includes information on sampling locations and conditions, sample archiving and quality reports of collected samples. Data and metadata are openly accessible and can be downloaded from the associated GitHub repository. Sequence data can be accessed via the European Nucleotide Archive (ENA) through the corresponding accession numbers. Images of ARMS plates are stored on PlutoF and can be downloaded through links provided in this paper. Sequence data were processed and explored with the PEMA pipeline, resulting in 17,194, 7,235 and 5,261 unique ASVs/OTUs for COI, 18S and ITS, respectively. In this dataset, ARMS revealed the presence of over 61 eukaryotic phyla, aligning with our previous sampling campaign. Amongst these phyla, 35 had sequences identified to the species level. With this dataset and its associated paper, we provide a standardised resource for marine biodiversity monitoring and scientific analyses of benthic biodiversity. The presented data product supports future studies on the status and changes in species composition, distribution and genetic diversity.

Background: The Haiha Mountain Stream Keelback, Opisthotropis haihaensis Ziegler, Pham, Nguyen, Nguyen, Wang, Wang, Stuart & Le, 2019, was originally described based on a single female specimen from northern Vietnam. To date, only two female specimens have been reported, rendering O. haihaensis one of the least studied members of its genus.

New information: During recent herpetological surveys in Guangxi Zhuang Autonomous Region, southern China, one male and one female specimen of Opisthotropis were collected from Qinzhou City. Phylogenetic analyses and detailed morphological comparisons identified these individuals as O. haihaensis. Based on these new specimens, we provide the first description of the male of this species, including hemipenial morphology, along with revised diagnostic features and new data on its natural history and distribution.

Background: Historical data on invertebrates are rare and their preservation and FAIR publication are of high importance. Systematically collected historical data can greatly improve the baselines against which trends in biodiversity of these groups are measured. Therefore, we started a data publication project to digitise and publish one of the longest-running insect monitoring schemes in the world.

New information: The raw data presented in the dataset have not been published before. It consists of 45,486 records of 90,070 specimens from 134 species of ground beetles caught between 1959 and 1966 in the Province of Drenthe, the Netherlands. All specimens were identified to species level by taxonomic specialists. The data were collected using a standardised field study set-up with pitfall traps. Extensive cross-checking during digitisation guaranteed an error rate of < 0.1%.The dataset presented here forms part of a much larger dataset of 300,000 records and close to 1 million individuals of 172 ground beetle species collected in the same area from 1959 to the present day, which will be further digitised in the coming years. The first part of the dataset has been registered in the Global Biodiversity Information Facility (GBIF) and can be found under: https://doi.org/10.15468/3mcqja.

Background: The subfamily Panchaetothripinae Bagnall (Thysanoptera, Thripidae) comprises about 150 species belonging to 42 genera worldwide. Amongst these, twelve species belonging to six genera were previously recorded from the Arabian Peninsula, including eight species in four genera from Saudi Arabia. The Faunistic studies on the subfamily have been confined to the tropical and subtropical parts of Africa, America, Southeast Asia and Australia. However, the tropical regions of the Arabian Peninsula remained under-studied, with no considerable work having been done on this subfamily.

New information: We present the first illustrated key to the Panchaetothripinae genera of the Arabian Peninsula and a checklist of Arabian species to facilitate their recognition. Moreover, two genera and species, Hercinothrips femoralis (Reuter) and Rhipiphorothrips cruentatus Hood, are recorded as new to Saudi Arabia. New distributional data for each species is also given. The presence of greenhouse thrips Heliothrips haemorrhoidalis Bouche in the country is doubtful. The species has not been recovered despite extensive surveys across the country spanning over six years. However, it is kept in the Arabian species list until further confirmations.

Background: The second manuscript in the series "Dalberto Teixeira Pombo (DTP) Arthropod Collection" focuses on Algar do Carvão, a remarkable volcanic pit on Terceira Island, Azores, that is a Natural Monument, a show cave and part of the Terceira Island Natural Park. This volcanic cave is unique amongst the archipelago's subterranean systems due to its distinctive geological features, including rare silica-based speleothems and its exceptional natural setting. Surrounded by remnants of native laurel forest, the cave hosts a specialised assemblage of arthropods, including several taxa endemic to the Azores and single island endemic species. Of particular interest are four obligate cave-dwelling species or subspecies (troglobionts): the centipede Lithobius obscurus azoreae Eason & Ashmole, 1992 (Chilopoda, Lithobiomorpha, Lithobiidae); the springtail Pseudosinella ashmoleorum da Gama, 1988 (Collembola, Entomobryomorpha, Entomobryidae); the spider Turinyphia cavernicola Wunderlich, 2008 (Arachnida, Araneae, Linyphiidae); and the ground beetle Trechus terceiranus Machado, 1988 (Insecta, Coleoptera, Carabidae), the last two being endemics to Terceira Island. These species are part of a fragile and narrowly distributed subterranean fauna shaped by the volcanic origin of the island and its isolation (0.4 Ma). Their presence highlights the conservation value of Algar do Carvão, which serves not only as a cave biodiversity hotspot, but also as a natural laboratory for studying evolution, adaptation to subterranean habitats and island biogeography. Despite being a show cave with frequent human visits, Algar do Carvão retains a relatively intact hypogean ecosystem, though it remains vulnerable to anthropogenic pressures, such as habitat disturbance and pollution.

New information: Particular focus is given to the abundance and population trends of the endemic cave-adapted beetle Trechus terceiranus, monitored through a long-term standardised programme initiated in 1999 using non-lethal trapping methods. This effort, designed to monitor population variation across seasons and years and to evaluate the potential impacts of increasing human visitation to the cave, represents one of the few continuous monitoring programmes for cave arthropods on oceanic islands. Over the course of this study, we also report the first citation of 21 arthropod taxa for Algar do Carvão, two of which are endemic to the Azores (Canariphantes acoreensis (Wunderlich, 1992) and Phloeostiba azorica (Fauvel, 1900)), contributing significantly to the known biodiversity of this volcanic pit, in particular and of Azorean subterranean fauna, in general.

Background: A bryophyte diversity survey was carried out from July 29 to 1 August 2013, in Santa Cruz das Flores, Flores Island (Azores) (39.471185 N Latitude; -31.184692 W Longitude), along an elevational gradient (70, 200, 400, 600 and 800 m a.s.l.). The study employed the Global Island Monitoring Scheme (GIMS) protocol for bryophytes. At each elevation level, three replicates of six substrates colonised by bryophytes (rock, soil, humus, dead wood, tree trunks, leaves) were collected. In total, 385 sampling events generated 1345 species occurrence records, representing 89 bryophyte species (37 mosses; 52 liverworts).

New information: The acrocarpous moss Fissidens azoricus (P.de la Varde) Bizot, listed as "Critically Endangered" by the IUCN, had not been reported from Flores Island since 1937; this is the first publication with new locations for the species.The altitudinal gradient revealed an increase in species richness and abundance with elevation, following a mid-elevation peak pattern, with the highest richness between 400 m a.s.l. (52 species; 364 records) and 600 m a.s.l. (54 species; 402 records), followed by a decline at 800 m a.s.l. (33 species; 148 records). At 70 m a.s.l., 20 species were identified (128 records) and, at 200 m a.s.l., 35 species were recorded (232 records). In terms of substrate preference, the highest species richness and abundance were found colonising epiphytic substrates (58 species; 424 records), followed by terricolous substrates (44 species; 233 records).

Background: The genus Atkinsonia in the family Stathmopodidae comprises 13 species described worldwide and only one is recorded from the Korean Peninsula. Despite this low species richness, the genus shows broad ecological diversity at the larval stage, ranging from phytophagy to carnivory, which supports the need for a comprehensive taxonomic study.

New information: We report Atkinsonia beijingana as a newly-recorded species from the Korean Peninsula. We describe the adult morphology and genitalia. A worldwide checklist of Atkinsonia species and their distributions is also provided to improve understanding of the genus.

Background: The genus Metapocyrtus Heller, 1912, is the most speciose and taxonomically complex genus in the tribe Pachyrhynchini. Currently, the genus is comprised of more than 250 species that are classified into seven subgenera. One of the least studied subgenera under the genus Metapocyrtus is the subgenus Dolichocephalocyrtus Schultze, 1925, whose members are generally known for their long and slender rostrum (0.60 to 0.76 times as long as wide). Another distinct feature of this subgenus is the evident sexual dimorphism: males possess elytra with a rounded apex and a steep apical declivity, while females exhibit a sharply pointed, triangular projection at the elytral apex. Like most weevils under the genus Metapocyrtus, species under the subgenus Dolichocephalocyrtus have a narrow geographic range due to their flight inability; this is probably the reason why all known species under this subgenus are endemic to the Philippines.

New information: A new species of flightless weevil, belonging to the genus Metapocyrtus Heller, 1912, subgenus Dolichocephalocyrtus Schultze, 1925, from the Aliwagwag Protected Landscape (APL), Cateel, Davao Oriental, Mindanao, Philippines, is described and illustrated. Named after the Aliwagwag Falls, the novel species, Metapocyrtus (Dolichocephalocyrtus) aliwagwag Pajota & Cabras, sp. nov., is the first species of the genus to be formally described from Cateel, Davao Oriental. The description of this novel species adds to the rich diversity of the genus Metapocyrtus in the country and highlights the ecological significance of the Eastern Mindanao Biodiversity Corridor (EMBC).
