Hello,
Reviewing horizon scanning articles for present emerging or future potential IAS, the species Alexandrium catenella was listed (in: Carboneras, C., Genovesi, P., Vila, M. et al. (2018) A prioritised list of invasive alien species to assist the effective implementation of EU legislation. Journal of Applied Ecology 55). 
Is it a synonym of Alexandrium acatenella? If not, should it be added to the Catalogue?

Alexandrium catenella is distinct from A. acatenella.
A. catanella status is obscure, as it happens for all phytoplankton species in Europe. The species is included in Aquanis base, but with a remark "cosmopolitan".
Based on Gomez 2008 the species should be considered as native in Europe.
I would be reluctant to include the species in the EASIN Catalogue.
