Aphelocheirus aestivalis, a waterbug found in mid and high sections of well-oxygenated and preserved rivers in the European continent, has been found for the first time in Catalonia (Spain), specifically in the rivers Ter and Llobregat, according to an article published in the journal Limnetica. This discovery confirms the presence of this insect from the Aphelocheiridae family in the Iberian Peninsula and enables the incorporation of a new family of Heteroptera in Catalan fauna.
