De Amerikaanse brakwaterstrandschelp Rangia cuneata nu ook in Groningen

Rangia cuneata (Sowerby I, 1832) is only very recently discovered in western Europe. In the Netherlands the species is only known living near Amsterdam, in the Noordzee canal and in the Gent-Terneuzen canal. In 2012, in the Termunterzijldiep, province of Groningen, I found empty valves of this species. In 2013 its occurence was better investigated. It is found in the Termunterzijldiep occurring from Termunterzijl to Nieuwolda, about 9.0 km inland. Based on these records and their size it is concluded that the species occurs here at least since 2008. This is the third known population in the Netherlands.
