Historical review of Dutch Pectinariidae with Pectinaria belgica as a new taxon for the Netherlands (Annelida: Polychaeta: Pectinariidae)

Two trumpet worms (Pectinariidae), which do not resemble the two known species: Lagis koreni Malmgren, 1866 and Amphictene auricoma (Müller, 1776), have recently been collected in the Dutch North Sea (Oyster Grounds). Their characteristics match those of Pectinaria belgica (Pallas, 1766), a species with a northern distribution. This paper summarizes the current state of knowledge of Dutch Pectinariidae and describes in detail the historical records of trumpet worms recorded in the Netherlands, along with the confusion around the species epithet belgica. Pectinaria belgica is reported here for the first time from the Dutch North Sea.
