Article Reference First observations in Belgium of the introduced ‘minute hooded beetle’ Arthrolips fasciata (Erichson, 1842) (Coleoptera: Corylophidae)
In September 2020 a specimen of the Corylophidae Arthrolips fasciata (Erichson, 1842) was discovered in mushrooms on decaying beech in a garden in Sint-Denijs-Westrem. In October 2020 a second specimen of this species was discovered in Beisbroek Sint-Andries Bruges also on decaying beech. These are the first records of the species in Belgium. Hence, we expect more Belgian records of this species in the near future. A species list of the Corylophidae known to occur in Belgium is given.

Article Reference First occurrence of a Hymenosomatid crab Elamena mathoei (Desmarest, 1823) (Crustacea: Decapoda: Brachyura) in the Mediterranean Sea.
Mediterranean fauna is undergoing drastic modifications as a result of anthropogenic activities and global warming. The most important of these is the colonization of the Mediterranean Sea by alien species, many of them entering through the Suez Canal. While many of them are still confined to the Levant Basin, several have extended their distribution westwards to Tunisian waters. The presence of the Indo-west Pacific hymenosomatid crab Elamena mathoei on a rocky shore at Sidi Daoud, Cape Bon Peninsula, Tunisia, is the first Mediterranean record of this species. It is a testimony to the changes in the patterns of invasion in the Mediterranean Sea.

Article Reference First Old World record of the poorly known, swan-sized anseriform bird Paranyroca from the late Oligocene/early Miocene of France
A tarsometatarsus of a large anseriform bird from the late Oligocene/early Miocene of the Saint-Gérand-le-Puy area in France is assigned to the distinctive taxon Paranyroca, which was before only known from the early Miocene of North America. Paranyroca may be a stem group representative of Anatidae and its tarsometatarsus exhibits a peculiar character mosaic, with an Anhimidaelike hypotarsus and an Anatidae-like distal end. With regard to these features, the bone resembles the tarsometatarsus of another anseriform bird from Saint-Gérand-le-Puy, which was described as Cygnopterus alphonsi but has not yet been compared with Paranyroca in the original description. C. alphonsi was originally identified as a swan, but this classification has subsequently been contested and here it is proposed that the species is more closely related to Paranyroca.

Article Reference First outdoor record of Crematogaster scutellaris (Olivier, 1792) in Belgium (Hymenoptera: Formicidae)
We report the first observation of an outdoor nest of the ant species Crematogaster scutellaris (Olivier, 1792) in Belgium. In spring 2022, a nest of this species was discovered at Rood Klooster in Auderghem, Brussels Capital Region. Large and very active trails of workers were detected in a hedge and along the walls of a small building. The nest is probably already present several years and situated in the wooden construction of the building. Interactions with other ant species indicate that this new arrival will not immediately become an invasive problem for the local native ant fauna. We expect that more records of this species might be discovered in the near future in the neighborhood but also elsewhere in Belgium.
