Abstract Studying the early stages of introduction non-indigenous species (NIS) is crucial as it allows immediate management actions aimed at preventing NIS spread a time when these are more likely to be effective. Recent introductions present unique opportunities study key aspects invasion process. However, comprehensive information on how and first introduced remains rare. We assessed characteristics member widespread Pyura stolonifera group (Chordata, Tunicata) in Europe. These ascidians important bioengineer that can attain amongst highest benthic biomass per surface area ever reported. collected individuals coast northwestern Iberian Peninsula, an with high shipping traffic one world’s most mussel farming regions. The specimens were analysed using taxonomic genetic tools. Both field surveys analysis showed African members group, herdmani , has recently been Europe and, although does not yet form large aggregates found native range, already well-established. Genetic data revealed only northwest lineage P. Considering low dispersal capabilities life-history this into explained via human mediated transport NIS. In order prevent any detrimental effects both biota and/or economically-important anthropogenic activities, regular monitoring recent urgently required.
