Abstract

This paper aims mainly to provide clarity on the morphological characters of the type species of Ampharete, Ampharete acutifrons (Grube, 1860). Its common occurrence and wide distribution are most likely a result of misidentification of different species. Possible reasons for that are the brief original description of this species that is available solely in Latin and a series of questionable synonymizations, resulting in a confusing history of A. acutifrons. In addition to a detailed redescription of the holotype of A. acutifrons, we describe an Ampharete species from the Baltic Sea that has also been incorrectly identified as A. acutifrons for many decades. The individuals of this species agree in all diagnostic characters with those of the Northwest Atlantic species Ampharete cirrata Webster & Benedict, 1887. Since no differences were found, but it is clearly distinct from A. acutifrons, A. cirrata is recognised as a valid species and consequently deleted from the synonym list of...
