Article Reference Species distribution, hybridization and connectivity in the genus Chionodraco: Unveiling unknown icefish diversity in antarctica
Aim: The species of the genus Chionodraco (Notothenioidei) are the most abundant icefish on the continental shelf of the Weddell Sea. While previous studies indicated that only Chionodraco hamatus and Chionodraco myersi inhabit the Weddell Sea, the third Chionodraco species, Chionodraco rastrospinosus, was recently sampled in the area. As C. rastrospinosus is supposed to be found only at the Antarctic Peninsula and Scotia Arc, this study aimed at confirming the species classification of C. rastrospinosus by molecular methods and identifying its putative source population. Given the documented evidence of introgression among the three species, we tested whether the newly found C. rastrospinosus shared any genetic variability with the other Chionodraco species. To explain the pattern of distribution of the Chionodraco species, we aimed at estimating the hydrodynamic connectivity between the Antarctic Peninsula and the Weddell Sea. Location: Antarctic Peninsula, southern Scotia Arc and the south-eastern Weddell Sea. Methods: We genotyped 19 microsatellites and sequenced the mitochondrial D-loop for 560 Chionodraco individuals. We simulated the dispersal of more than 3 million drifters (Lagrangian model). Results: The molecular analyses support the presence of C. rastrospinosus in the Weddell Sea and its homogeneity with C. rastrospinosus from the Antarctic Peninsula. Bayesian clustering identifies three putative hybrids among C. rastrospinosus and the other congenerics. Lagrangian simulations do not support connectivity driven by the oceanographic features of the Antarctic Peninsula and Weddell Sea via passive larval dispersal only. Main conclusions: This study documents, for the first time, the presence of C. rastrospinosus in the Weddell Sea unveiling more biodiversity than previously known in this region. The sympatry of the three Chionodraco species explains the occurrence of occasional, ongoing events of hybridization in the genus. Alternative possible

Article Reference Review of the historical collection of Charipinae (Hymenoptera: Figitidae) preserved in the RBINS
Specimens from the subfamily Charipinae (Figitidae) deposited in the Royal Belgian Institute of Natural Sciences (RBINS) were examined, in total 44 individuals were identified, belonging to eleven species. Five species are reported for the first time in Belgium: Alloxysta citripes (Thomson, 1862), A. fuscipes (Thomson, 1862), A. halterata (Thomson, 1862), A. ramulifera (Thomson, 1862) and Phaenoglyphis fuscicornis (Thomson, 1877); making 14 known species of Charipinae in Belgium. Additionally, for the first time, host information is reported for P. fuscicornis and A. consobrina (Zetterstedt, 1838).

Article Reference Overview of myrmecological studies and a checklist of the ants (Hymenoptera, Formicidae) of the Democratic Republic of Congo
The production of species checklists is fundamental to setting baseline knowledge of biodiversity across the world and they are invaluable for global conservation efforts. The main objective of this study is to provide an up-to-date extensive checklist of the ants of the Democratic Republic of Congo (DRC), the largest country in sub-Saharan Africa, based on available literature to serve as a foundation for future research and ant faunistic developments. We gathered the literature available to us, most of it compiled from the Global Ant Biodiversity Informatics (GABI) Project and treated the data to province level when possible. We also offer insight into who, when and where contributions have emerged to the current knowledge of the ants of the DRC and each of its 26 provinces. The current list is restricted to valid species and subspecies, discarding morphospecies and some misidentified taxa. The list comprises eight subfamilies, 64 genera and 736 species, the highest species diversity for a country located within the Afrotropical realm.

Article Reference First record of three alien termite species in Belgium
Subterranean termites (Family Rhinotermitidae) and drywood termites (Family Kalotermitidae) can be pest species as they have the potential to inflict damage to wooden constructions and can therefore cause a significant economic impact. Some species of these families are highly destructive and are invasive in many parts of the world. New introductions and/or the spread of termites are often caused by import of infested wood, plants or soils. The present study reports the first records of three exotic termite species in Belgium, viz. Cryptotermes brevis and Reticulitermes banyulensis in Brussels (Brussels Capital Region), and Reticulitermes flavipes in Brugelette (Hainaut province; Walloon region). The morphological identification of the specimens (N = 8) was validated by DNA-barcoding. Cryptotermes brevis and Reticulitermes banyulensis infestations are probably of little concern as local climatological conditions make it unlikely for either species to survive in the temperate climate in Belgium. In contrast, it is likely that Reticulitermes flavipes may become established and will spread to other sites in Belgium.
