Background: Chironomidae, with over 7,300 described species, are amongst the most diverse and abundant insect families in freshwater ecosystems worldwide. Chironomids are known for their widespread distribution from various water types. The level of documentation of chironomid fauna varies considerably amongst European countries, with more comprehensive knowledge for Western Europe compared to other regions. Despite the recent extensive sampling effort and the increasing number of available data, the chironomid fauna of Central European countries still remains poorly known.

New information: This study contributes to the knowledge of chironomid fauna in three river catchments in Croatia, Hungary and Czechia. A combination of morphological and molecular techniques was employed, with a focus on larvae, although pupae and exuviae were also examined. We found 207 taxa, amongst which 170 were identified to species level. In Croatia, 14 species were recorded for the first time and two species were newly recorded in Czechia. DNA barcoding of 31 specimens resulted in 23 BINs, including eight new ones to BOLD. We provided detailed notes on taxa with taxonomic problems and/or morphological peculiarities. Our results highlight that extensive studies conducted in relatively small areas and a limited range of habitats (only streams in hilly regions) can remarkably contribute to the local and global knowledge on Chironomidae fauna, especially when the taxonomically difficult and often problematic larvae are investigated.

Background: Approximately twenty-one years of historical mosquito abundance and species surveillance data, collected by the University of Notre Dame and the St. Joseph County (IN) Health Department, from 1976 to 1997 are made available following a data rescue effort. St. Joseph County is a county in Indiana, located on the Michigan-Indiana border, 35 miles from Lake Michigan.

New information: The collected data will allow for trends in species to be followed over a wide time range and facilitate further research regarding mosquito-borne diseases, species distribution, phenology and ecological changes over time.

Background: Ulleungdo and Dokdo, located in the East Sea, are volcanic islands with high ecological value due to their unique biodiversity. Although research on the insect fauna on these two Islands has been conducted from the early 19^th century to recent times, limitations exist due to several issues, including misidentifications and historical errors. This study addresses these issues by conducting a comprehensive insect survey from 2020 to 2023, re-identifying misidentified specimens and compiling references to create an updated and accurate checklist of insect species for Ulleungdo and Dokdo.

New information: The checklists include 20 orders, 227 families and 1694 species, including 28 previously unrecorded species for Ulleungdo Island: Neoitamuscothurnatusunivittatus (Loew, 1871), Elachipterainsignis (Thomson, 1869), Elachipterasibirica (Loew, 1858), Muscinalevida (Harris, 1780), Orchisiacostata (Meigen, 1826), Ensinasonchi (Linnaeus, 1767), Armigeressubalbatus (Coquillett, 1898), Aedeskoreicus (Edwards, 1917), Aedesgalloisi Yamada, 1921, Aedesalbopictus (Skuse, 1894), Aedestogoi (Theobald, 1907), Stenolophusdifficilis (Hope, 1845), Dasytesvulgaris Nakane, 1963, Attaluselongatulus Lewis, 1895, Elacatiskraatzi Reitter, 1879, Polygraphusjezoensis Niisima, 1909, Scolytoplatypustycon Blandford, 1893, Ambrosiophilusatratus (Eichhoff, 1876), Psilarthroidesczerskyi (Zaslavskij, 1956), Tomoxianipponica Kôno, 1928, Adelphocorisdemissus Horvath, 1905, Corythuchamarmorata (Uhler, 1878), Spilarctiaseriatopunctatasuzukii Inoue & Maenami, 1963, Hypopyravespertilio (Fabricius, 1787), Simpliciarectalis (Eversmann, 1842), Acronictahercules (Felder & Rogenhofer, 1874), Analetiapostica (Hampson, 1905) and Eudemisbrevisetosa Oku, 2005; 10 orders, 80 families and 201 species, including three unrecorded species for Dokdo Island: Arhopaloscelisbifasciata (Kraatz, 1879), Nabisstenoferus Hsiao, 1964 and Haplogonatopusoratorius (Westwood, 1833).

Background: Earthworms are one of the most important components of temperate ecosystems and groups of soil animals globally, but data on their distribution around the world are still incomplete and uneven. Northern Eurasia is a region for which available data on earthworm distribution is extremely poor. At the same time, generations of Soviet and Russian researchers have performed extensive research and accumulated a large amount of data on the distribution of earthworms in this vast region. Most of this information was published in Russian, not digitised and, therefore, hardly accessible to researchers. Our dataset fills this gap and provides occurrence data extracted from 159 literature sources in Russian published between 1868 and 2022. The dataset contains 5,304 occurrences of 109 species and 14 subspecies. The collected data cover the territory of 27 countries.

New information: The dataset extends the data available through GBIF.org on earthworm distribution in Russia, Belarus, and Ukraine. For Transcaucasia and Central Asia countries, our resource has become the main GBIF source on earthworm diversity distribution. On a global scale, our dataset contributes to filling gaps in biodiversity, which facilitates more accurate estimates of the response of biodiversity to global climate change as well as the spreading of invasive species.

Understanding how abiotic factors influence Bornean tropical tree communities and diversity is a key aspect in elucidating the mechanisms of species co-existence and habitat preferences in these biodiverse forests. We focused on investigating forest structure, tree diversity and community composition of lowland Bornean heath forests in Brunei Darussalam, within two 0.96 ha permanent forest plots at Bukit Sawat Forest Reserve and Badas Forest Reserve. All trees with stem diameter ≥ 5 cm were tagged, identified and measured for their stem diameter and basal area. Soil physiochemical properties (pH, gravimetric water content and concentrations of total carbon, nitrogen, phosphorus, potassium, calcium and magnesium in topsoil) and environmental factors (relative humidity, canopy openness, litter depth and topographic variables of elevation, slope and aspect) were quantified as potential drivers of tree community differences. A total of 2,368 trees were recorded, representing 229 tree species in 211 genera and 58 families. Significant between-site differences in forest structure and tree community compositions were detected, despite limited differences in environmental and soil properties. Tree community composition at Bukit Sawat appeared to be influenced by topographic variables, while those at Badas were influenced by canopy openness. Our results showed that small-scale soil and environmental variation appeared to shape the local tree communities at Bukit Sawat and Badas. We recorded numerous Bornean endemic and tree species of high conservation values. We thus highlight the necessity of conducting long-term research on the forest dynamics of Bornean heath forests to effectively manage these high conservation value habitats which are currently experiencing changes driven by disturbances.

Background: The spider genus Choiroblemma Bourne, 1980 of the family Tetrablemmidae currently contains two species, C.bengalense Bourne, 1980 and C.rhinoxunum Bourne, 1980. Both species are known from West Bengal, India.

New information: A new species of Choiroblemma is described from Xizang, China, Choiroblemmametok sp. nov. (♂♀). Morphological descriptions, photomicroscopy images of the new species and a distribution map of Choiroblemma species are given.

Background: The Amazon Rainforest, a paramount source of global biological diversity, faces challenges due to its understudied species richness, an insufficient investment in research and escalating rates of deforestation. Thus, acquiring additional data, especially for species distributions is crucial to fill knowledge gaps and guide forthcoming research and conservation initiatives in areas that have been inadequately sampled. This study contributes to addressing these challenges by offering new insights into the diversity and distribution of Pitcairnia species in the Brazilian Amazon.

New information: We recorded 24 species of Pitcairnia for the Brazilian Amazon, of which nine species are endemic to Brazil and seven are endemic to the Brazilian Amazon Basin. Most species can be rupicolous and have distributions in the Amazon Basin that are influenced by rivers and other watercourses. One species (P.aureobrunnea Rauh) was recorded for the first time in the Brazilian Amazon and two new Pitcairnia species were discovered and are being described in separate articles, contributing to the expanding body of scientific knowledge.

Background: The univoltine leaf beetle Phyllotretaochripes (Curtis, 1837b) is native to the Palaearctic Region from Japan to western Europe.This species was previously evaluated as a potential biological control agent against invasive populations of the woodland weed Alliariapetiolata (Bieb.) Cavara & Grande (Brassicaceae) in North America, but rejected because it could harm native and at-risk populations of Brassicaceae.

New information: First North American records are presented for Phyllotretaochripes (Curtis, 1837). Specimens were examined from the USA: Illinois, Maryland, Michigan, Ohio and Pennsylvania. Internet photographs of apparent additional individuals from USA: Indiana, Michigan, Minnesota, Ohio, Pennsylvania, Tennessee, Wisconsin and Canada: Ontario were also examined. DNA barcoding analysis showed high genetic variability and possible cryptic species within European populations of P.ochripes. Diagnostic information is presented to distinguish P.ochripes. from other North American Chrysomelidae and a species distribution model to assess its potential spread in North America is presented.Phyllotretaochripes breeds on invasive garlic mustard, Alliariapetiolata (Bieb.) Cavara & Grande (Brassicaceae) and also non-native Rorippaamphibia (L.) Besser and other species of Brassicaceae.A species distribution model and the range of its host plant A.petiolata, indicates the most suitable conditions for this species are in humid areas of eastern North America. However, most of the known records of this species were discovered in areas projected to have low suitability. This is likely a consequence of sampling bias towards western Europe and away from the eastern Asian portion of its native range. The United States of America and Canada are now known to be home to 72 or more species of adventive Chrysomelidae.

Background: Cumaceans mostly inhabit marine environments, where they play a crucial role in marine food webs and actively participate in the transfer between benthic and pelagic systems. Scientific interest in these crustaceans has been increasing, but is limited to certain geographic areas, which do not include extreme environments such as hydrothermal vents.

New information: Therefore, this study aimed to report the distribution of cumaceans in shallow-water hydrothermal vents at Banderas Bay and to identify the specimens present. Three sites were selected (20°44'54.7"N, 105°28'40.6"W; 20°44'54.8"N, 105°28'40.4"W; 20°44'54.9"N, 105°28'38.4"W) and each site was divided into three zones, based on sediment temperature. Through SCUBA diving, 27 sediment cores were collected. The samples were processed and identified in the laboratory. The families Bodotriidae T. Scott, 1901; Pseudocumatidae Sars, 1878; and Diastylidae Bate, 1856; were recorded and six morphospecies were identified. This work leaves a preliminary frame of reference for future studies related to the biodiversity of cumacean in Hydrothermal vents environments.
