Article Reference Paracrenhydrosoma oceaniae sp. nov. (Copepoda: Harpacticoida), from Kongsfjorden, Northwest Svalbard (Arctic)
Both sexes of a new species of Cletodidae belonging to the Acrenhydrosoma-lineage are described from material collected at Kongsfjorden (Svalbard) and attributed to the genus Paracrenhydrosoma Gee, 1999. Paracrenhydrosoma oceaniae sp. nov. is easily distinguished from its congeners by the reduced setal formula of the natatorial legs, lacking the inner subdistal seta on segment 3 of legs 3 and 4. Several other characteristics viz. antennular and antennal armature, and the free leg 5 exopodite in both sexes, are indications of its basal position in the genus.

Article Reference Parallel phenotypic evolution in a wolf spider radiation on Galápagos.
Within island archipelagos, repeated ecological settings may lead to radiations wherein similar niches are recurrently occupied. Although it has been shown that species with common habitat requirements share particular traits, it remains relatively unexplored to what extent this may lead to the repeated evolution of almost identical phenotypes (phenocopies) and how this correlates with traits subjected to sexual selection. Exploring divergence patterns of ecological and sexual relevant traits within spiders seem promising to enhance our understanding of the relative role of natural and sexual selection. Here, we conduct a detailed morphological analysis on a large set of genital and non-genital traits (morphometrics, colour pattern) within a radiation of the wolf spider genus Hogna Simon, 1885 on Galápagos and interpret these data, taking into account their known phylogenetic relationship. Our results show that recurrent environmental gradients have led to the parallel evolution of almost identical phenotypes, which not only proves that natural selection has driven morphological divergence, but also suggests that a similar genetic or developmental basis most likely underlies this divergence. Among-species variation in genital traits in contrast rather reflects the phylogenetic relationships on Santa Cruz and San Cristóbal. The combination of these data indicate that speciation in this system is driven by the combined effect of ecological mechanisms and allopatric divergence in sexual traits.

Article Reference Parasite introduction with an invasive goby in Belgium: double trouble?
Non-indigenous species may have negative impacts on the native fauna in their competition for food and habitat, but they can also introduce non-indigenous parasite species, with sometimes devastating consequences. Cointroduction of parasites should therefore be carefully monitored, but this aspect is mostly overlooked. The round goby Neogobius melanostomus (Pallas, 1814) and the tubenose goby Proterorhinus semilunaris (Heckel, 1937), both known for their invasiveness, have recently been discovered in Belgium. Here, we morphologically and genetically document the cointroduction of the Ponto-Caspian Gyrodactylus proterorhini Ergens, 1967, originally described on tubenose goby in southern Slovakia. Because of their direct life cycle and extraordinary reproductive capacities, gyrodactylid monogenean parasites can readily invade new areas together with the host. Moreover, G. proterorhini has a wide host range and might therefore represent a threat to other gobiid fishes. The Gyrodactylus parasite found on the Belgian round goby population is probably acquired through secondary infection from local fish, as suggested by molecular phylogenetic analysis.
