Article Reference Redescription of Teretoctopus alcocki Robson, 1932 (Cephalopoda: Enteroctopodidae), and comments on the nomenclature of “inkless octopus” genera
Two species have been attributed to the genus Teretoctopus Robson, 1929: T. indicus Robson, 1929, the type species of the genus, and T. alcocki Robson, 1932. Of the four original T. alcocki syntypes, we relocate and redescribe the remains of two of them, and designate one of them the lectotype. Of three original T.indicus syntypes, it is probable that one is lost permanently, but the whereabouts of two of them remains unknown. What we can discern from remaining T. alcocki type material, augmented with descriptions of these specimens by Anne Massy and Guy Robson, is compared with what is known of the type species of this genus, T. indicus. A rediagnosis of the genus Teretoctopus is proffered, and relationships between this genus and others historically referred to as “inkless octopuses” are evaluated. While Teretoctopus has nomenclatural priority over Vulcanoctopus González et Guerra, 1998 and Muusoctopus Gleadall, 2004, for which it is possibly the senior synonym, and shares many characters and states with Ameloctopus Norman, 1992, further taxonomic resolution of relationships among these genera must await description and molecular analyses of accurately identified Teretoctopus specimens from the Gulf of Oman and northern Arabian Sea.

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.

Article Reference Familie-indeling en diversiteit van wespen (Hymenoptera) in de Lage Landen
De classificatie van de families van de orde Hymenoptera is de afgelopen vijf jaar aanzienlijk veranderd, onder meer door meer moleculair onderzoek. De evolutionaire geschiedenis van de orde wordt ook steeds duidelijker. Op basis van onderzoek uit recente literatuur en in lijn met nieuwe inzichten presenteren wij een nieuw familieoverzicht voor Nederland en België. In Nederland en België zijn vertegenwoordigers gevonden van 88 families. Om een idee te krijgen van de diversiteit van de verschillende families wordt een overzicht gegeven van het aantal genera en het (geschatte) aantal soorten voor elke familie. Deze cijfers zijn gebaseerd op literatuuronderzoek, websites of deskundig oordeel van specialisten. Een groot aantal foto’s toont de enorme soortendiversiteit van de wespen. Er valt echter ook in beide landen nog veel te ontdekken, vooral in de Parasitica-groep.

Article Reference Role of windbreaks on ants (Hymenoptera, Formicidae) conservation in a cotton-growing agroecosystem of the humid savannah in Togo
Intensive agriculture and monoculture lead to significant reduction, or loss, of the initial biodiversity. This reduction or loss of biodiversity, can be mitigated by the presence of windbreaks around the fields that serve not only as natural barrier against adverse weather conditions but also as refuge for critical organisms. The aim of this study was to determine the role of natural windbreaks in the conservation of ants at the Experimental Station of the Centre de Recherche Agronomique de la Savane Humide in Kolokop´e (Togo). Ants’ diversity was assessed in two cotton fields and their surrounding natural windbreaks using pitfall traps and monolith method in 100 m x 2 m transects. In total, 58 ant species belonging to 22 genera in six subfamilies (Dolichoderinae, Dorylinae, For- micinae, Myrmicinae, Ponerinae and Proceratinae) were identified. The species richness of ants was higher in the windbreaks (43 and 36 species) than the cotton fields (15 and 19). The occurrence of ants was also higher in the windbreaks (35.65 % and 36.24 %) than the cotton fields (11.69 % and 16.42 %). Thirty-four out of the 58 species were sampled exclusively in the windbreaks, compared to only two species exclusively sampled in the cotton fields (Crematogaster sp.3 and Lepisiota sp.3), while only three species were common for all the habitats (Camponotus flavomarginatus Mayr, 1862, Tetramorium sp.1 and Tetramorium simillimum (Smith, 1851)). The study shows that ants were more diversified and active in the windbreaks than the cotton fields. Windbreaks, characterized by less anthropic disturbance, could function as refuge for ants within this agroecosystem.

Inproceedings Reference Présence d'un gecko dans l'Eocène basal de Dormaal (Belgique): un élément thermophile du PETM ?
Si le registre fossile des lézards est assez bon pour l’Eocène moyen et supérieur en Europe, il n’en va pas de même pour l’Eocène inférieur. Seule la localité de Dormaal, datant de l’Eocène basal (niveau-repère MP7,Belgique) semble faire exception. Parmi les nombreux fossiles de lézards de cette localité, nous présentons ici pour la première fois quelques rares éléments appartenant à un gecko. Ce dernier vivait donc dans nos régions durant le Maximum Thermique Paléocène-Eocène (PETM), climat le plus chaud des 66 derniers millions d’années. Ce nouveau taxon, daté de 56 Ma, est le plus ancien gecko cénozoïque connu en Europe. Avec Laonogekko lefevrei de Prémontré (MP 10, Bassin de Paris), plus jeune d’environ 5 millions d’années, ces taxons forment la radiation du Paléogène inférieur de ce clade. Aujourd’hui, les geckos sont répartis dans le monde entier, principalement dans les zones tempérées chaudes à tropicales, bien que certaines espèces puissent atteindre des régions plus froides dans les hémisphères Nord et Sud. Le nouveau gecko de Dormaal représente un élément thermophile, confirmant les préférences thermiques actuelles des geckos. Par ailleurs, la distribution de ce groupe dans des latitudes aussi septentrionales (au-dessus de 50° Nord) n’est pas surprenante durant cette période particulièrement chaude. Bien que le nouveau taxon décrit ici ne soit représenté que par un frontal et des dentaires (deux des éléments les plus fréquemment préservés chez les geckos fossiles), il fournit un nouveau record de diversité des squamates à la base de l’Eocène. Avec Yantarogekko de l’ambre éocène de la Baltique (district de Kaliningrad, nord-ouest de la Russie), ces geckos documentent la distribution septentrionale des geckos en Europe pendant l’Éocène.
