Article Reference Going Dutch: Invasion pathways and current European distribution of non-native land flatworm species belonging to Geoplaninae and Bipaliinae with focus on the Netherlands
Non-native land flatworms can have a negative impact on local ecosystems, due to their voracious appetites for earthworms or snails. Accurate knowledge on the distribution of non-native populations of land flatworms is necessary to design effective policy to control their spread across Europe. The aim of this study is to address the spatiotemporal distribution of selected species of non-native land flatworms (Geoplaninae and Bipaliinae) in the Netherlands, and provide their current distribution and introduction pathways in a pan-European perspective. Specimens of Obama spp., Bipalium kewense and Diversibipalium multilineatum were reported across selected Dutch gardens, greenhouses, plant nurseries or garden centers. European distribution of these planarians species was reconstructed using previously published datasets and from records available on GBIF. Morphological species identification was supported by DNA barcoding using a portion of the 28S rDNA marker. Introduction pathways were addressed via haplotype networks based on COI mtDNA. In total, 27 specimens of non-native land flatworms were collected in the Netherlands. Their different spatiotemporal distribution pattern indicates differences in tolerance to environmental conditions in Northern Europe between B. kewense restricted to greenhouses and D. multilineatum found in gardens. Generally, an increasing trend in the number of records of Obama nungara is observed in the Netherlands and in Europe, with the highest number of records per country reported in France (1.428) followed by the Netherlands (149) and Italy (64). The high numbers of France are, however, artificial and originate from communication towards the public, which has not been as pronounced in other European countries. Genetic analyses suggest multiple introductions of O. nungara in Europe. The combination of morphological and molecular species identification revealed the presence of Obama anthropophila being the first record of this species outside its native range in Brazil. Our results further support the established status of these species in Europe and highlight the importance of citizen scientists in non-native species research.

Article Reference Unveiling hidden species diversity within Southern Ocean Iphimediidae (Crustacea, Amphipoda) through DNA and 3D-geometric morphometrics, with the description of 10 new species
The Antarctic shelf benthos is threatened by climate-related environmental changes and anthropogenic stressors. A baseline knowledge of biodiversity and species distribution ranges is essential for effective monitoring and conservation. Here, we integrate DNA-based species delimitation methods with morphological analyses to explore species diversity within Antarctic Iphimediidae. Our results reveal that ten nominal species are complexes of multiple species, most of which can be distinguished by small but consistent morphological differences. We formally describe ten of these new species: Stegopanoploea brevidentata sp. nov., Maxilliphimedia acutilobata sp. nov., Maxilliphimedia oliveri sp. nov., Echiniphimedia spinosior sp. nov., Echiniphimedia maxima sp. nov., Iphimediella longidentata sp. nov., Iphimediella brachyodonta sp. nov., Iphimediella longilobata sp. nov., Labriphimedia adeliae sp. nov., and Labriphimedia anneninae sp. nov. Most previously recorded circum-Antarctic iphimediid species are found to consist of regionally distributed species. Furthermore, we apply 3D-geometric morphometrics on the Gnathiphimedia sexdentata complex to investigate whether ‘cryptic’ species can be differentiated by variation in continuous morphological traits. This method provides additional diagnostic characters for the morphological identification of two G. sexdentata clades. This integrative taxonomy study increases the number of nominal Antarctic iphimediid species from 39 to 49, with 14 additional putative species requiring further study for formal description.

Article Reference Rediscovery of Camponotus herculeanus (Linnaeus, 1758) in Belgium (Hymenoptera: Formicidae)
Camponotus herculeanus (Linnaeus, 1758) was rediscovered in Belgium near Ouren. Throughout the spring and summer of 2023, workers were collected on multiple occasions in a Picea abies stand near the Belgian-German boarder.

Article Reference 107 Ants in the clouds: A preliminary checklist of the ant (Hymenoptera, Formicidae) fauna of a Honduran cloud forest ecosystem, featuring a key to country genera
Ant diversity in tropical montane rainforests is globally understudied. This is true for Cusuco National Park (CNP), a cloud forest ecosystem in northwestern Honduras that supports geographically isolated and threatened habitats. The current study presents the first comprehensive ant species checklist for CNP, which is also the first ant check- list for Honduras in over a century. Species records from several projects are also com- bined and presented. Sampling occurred along an elevational range (mainly between 1170 and 2030 m a.s.l.), with methodologies and intensities varying among projects and dates. Overall, 162 ant species belonging to nine subfamilies and 60 genera are reported from the CNP. Five species are recorded for the first time in Honduras (Pheidole natalie Longino, 2019; Strumigenys cf. calamita; Solenopsis invicta Buren, 1972; Solenopsis tex- ana/carolinensis; Pseudomyrmex pallens Mayr, 1870). For the first time, male individuals are reported in Pheidole balatro Longino, 2019. For each species, we provide informa- tion on observed habitat preference, elevational range, and sampling technique. Species accumulation curves are provided for each sample technique, representing sampling intensity and community sample coverage. We also provide a key to the ant genera of Honduras to aid future taxonomic efforts in the country. Our research demonstrates that CNP harbours a surprisingly rich diversity of ant species, despite its small area, similar to many other taxa in the park. The information provided here represents baseline infor- mation for future work on ants in CNP and other Honduran cloud forests and will help guide research in these otherwise poorly explored yet highly threatened ecosystems.
